Surgery For Urinary Incontinence Research Articles

Further developments of pubourethral ligament surgery for stress urinary incontinence.

Midurethral slings (MUS) have revolutionized the treatment of stress urinary incontinence (SUI). MUS operations work by creating a collagenous pubourethral ligament (PUL). Since 1996, more than 10 million operations have been performed worldwide. Early complications with the MUS included bowel perforations, massive retropubic hemorrhages, nerve injuries, even death. Though the invention of the transobturator tape (TOT) operation, and later, minislings, has eliminated many such complications, the most frequent complication, post-operative urinary retention, remains. MUS operations are unavailable in many countries because of expense. Low-cost surgical options discussed include the tension-free artisan minisling which uses a 10 cm × 1 cm tape inserted as a "U" below the urethra; 91% cure was achieved at 5.7 years in a study of 90 women, though it was accompanied by a 4.2% erosion rate. The more recent urethral ligament plication (ULP) is based on transperineal ultrasound studies which showed that the main cause of the SUI was elongation of weak PULs. This allowed the posterior pelvic muscles to open out the posterior urethral wall to cause SUI. Basic science collagen studies indicated that suturing PULs with No. 2 wide-bore polyester sutures would provide sufficient collagen to repair weakened PULs. Cure of SUI, when it occurred, was immediate. Reference to the original experimental animal studies indicated that collagen 1, the key structural support of PUL, had formed by 3 months. This is an optimistic sign for longer term cure, substantiated by very little deterioration after 3 months over a 12-month period in the first surgical trial (unpublished data). In conclusion, the ULP operation can be performed under local anesthesia/sedation. If it fulfils its promise for longer-term cure, SUI cure will be available for hundreds of millions of women in underdeveloped countries for a few dollars per case.

Cosmetic and functional impact of fascia lata harvest for use in surgery for stress urinary incontinence.

There has been increased interest in using autologous tissues since the Food and Drug Administration banned transvaginal mesh for pelvic organ prolapse in 2019. Our study aims to assess patients' perspective of functional and cosmetic impact on the fascia lata harvest site in patients undergoing fascia lata harvest for the treatment of stress urinary incontinence (SUI). This is a prospective survey study of a retrospective cohort of patients who underwent a fascia lata pubovaginal sling between 2017 and 2022. Participants completed a survey regarding the functional and cosmetic outcomes of the harvest site. Seventy-two patients met the inclusion criteria. Twenty-nine patients completed the survey for a completion rate of 40.3%. For functional symptoms, 24.1% (7/29) of patients reported leg discomfort, 10.3% (3/29) reported leg weakness, 10.3% (3/29) reported a bulge, 17.2% (5/29) reported scar pain, 14.8% (4/27) reported scar numbness, and 17.2% (5/29) reported paresthesia at the scar. For cosmetic outcomes, 72.4% (21/29) reported an excellent or good scar appearance. On the PGI-I, 75.9% (22/29) reported their condition as very much better (48.3%, 14/29) or much better (27.6%, 8/29). The majority of patients reported being satisfied with the functional and cosmetic outcomes of their harvest site as well as satisfied with the improvement in their SUI. Less than 25% of patients report harvest site symptoms, including leg weakness, scar bulging, scar pain, scar numbness, or paresthesia in the scar. This is important in the context of appropriate preoperative discussion and counseling regarding fascia lata harvest.

Pain Catastrophizing and Impact on Pelvic Floor Surgery Experience

ABSTRACT Duration, intensity, and management of pain and discomfort may all be affected by experience, personality, and medical and psychosocial comorbidities. A negative cognitive-affective response to actual or anticipated pain, which impacts the pain experience, is called pain catastrophizing. The scale utilized for identifying individuals who magnify, feel helpless to manage, anticipate, or ruminate on pain is known as the Pain Catastrophizing Scale (PCS) and is composed of a 13-question validated measure and 3 subscales. The scale's score ranges from 0 to 52, where scores of 30 and greater indicate pain catastrophizing (30 points is the 75th percentile for PCS score distribution in patients with chronic pain). Pain catastrophizing is associated with increased pain severity, pain persistence, and opioid consumption following surgery, as well as poorer response to endometriosis treatments. Approximately 300,000 prolapse surgical procedures are performed in the United States annually, and because little is known about pain catastrophizing on perioperative pain, pelvic floor symptom distress/impact, and voiding trial (VT) performance following urogynecologic surgery, the authors' primary aim was to assess baseline pain catastrophizing on preoperative pelvic floor symptom impact and distress. The secondary aims included assessing the impact of pain catastrophizing on voiding function and postoperative pain following pelvic floor surgery. The patients for this prospective cohort study included self-identifying female patients undergoing surgery for stress urinary incontinence (SUI) and/or pelvic organ prolapse from March 2020 to December 2021. Inclusion came following completion of appropriate surveys and subsequent surgery. Exclusion was merited through surgery for reasons besides SUI or prolapse. At the baseline patient visit, a PCS score of 30 or greater was defined as pain catastrophizing. The initial visit also included recording data such as body mass index, age, benzodiazepine use, chronic opioid use, anxiety and depression diagnoses, postoperative prolapse stage, bothersome urgency urinary incontinence, and preoperative postvoid residual volume. Charts were used for abstracting surgical data, such as operative time, estimated blood loss, type of pelvic reconstructive surgery performed, and midurethral sling placement. Surgeries were all performed by fellowship-trained reconstructive pelvic surgery providers. Postanesthesia care unit (PACU) nurses and clinic staff were masked to preoperative PCS scores obtained in the PACU and postoperative clinic visits. A standardized void trial was performed. Of 320 participants in this cohort, 46 had a pain catastrophizing score of ≥30. Mean age was 60.0 ± 12.8 years. Bivariate analysis indicated that the pain catastrophizing group had higher average body mass index and greater preoperative use of benzodiazepines. Variants such as SUI rates, urgency urinary incontinence, or prolapse stage had no significant differences between groups, yet preoperative pelvic floor symptom distress and impact scores were clinically and statistically significantly higher in the catastrophizing group. Higher PACU pain scores were associated with pain catastrophizing, but not first postoperative VT failure. A significant association between pain catastrophizing and symptom distress remained following multivariable analysis, as well as a relationship between high PCS scores and symptom impact. All quality-of-life subscales maintained the significant associations. This study, although unique in describing pain catastrophizing in this setting, includes various limitations such as its single-institutional nature, which may limit external generalizability. Furthermore, generalizability may also be limited for those electing nonsurgical management, as the study selected for women choosing surgery. Study strengths include its large number of patients cared for by fellowship-trained providers in a similar manner with uniform surgical practice and timing of measures for assessing pelvic pain and pelvic floor symptoms. Also, a relatively standard VT method was utilized. Although further investigation is warranted for describing pain catastrophizing and its role with pelvic floor symptoms and pain postoperatively, the results of this study support other investigative findings, which indicate the importance of understanding pain catastrophizing and its potential effect on patients undergoing pelvic floor surgery. Future studies around this relationship can potentially enable health care providers to tailor perioperative care for individuals with pain catastrophizing.

The Impact of Preoperative Pain on Outcomes After Vaginal Reconstructive Surgery and Perioperative Pelvic Floor Muscle Training

ABSTRACT In the United States, around 9 million women are affected by pelvic pain due to conditions such as interstitial cystitis/bladder syndrome, fibromyalgia, pelvic floor myalgias, chronic opioid use, or irritable bowel syndrome. Treatment options for concurrent pelvic floor disorders and pelvic pain can prove challenging due to the overall desire to avoid exacerbating overall pain while optimizing pelvic floor symptoms. The primary aim of this study was to compare both perioperative pelvic muscle training and vaginal reconstructive surgery among women who experienced or lacked preoperative pain and to inform better approaches to management of women with preoperative pain. The study was a secondary analysis of the Operations and Pelvic Muscle Training in the Management of Apical Support Loss (OPTIMAL) randomized clinical trial, as performed via the Pelvic Floor Disorders network. The main study's design was a 2 × 2 randomized factorial design with a surgical intervention and a perioperative behavioral intervention. The Eunice Kennedy Shriver National Institute of Child Health and Development data and specimen hub provided the data for this study. Included were 374 women undergoing surgery for both stress urinary incontinence and stage 2–4 pelvic organ prolapse from 2008 to 2013. All participants underwent vaginal prolapse repair and midurethral sling, and were randomized to either perioperative pelvic muscle therapy or usual care. The Pain scale, the Pelvic Floor Impact Questionnaire, the Pelvic Floor Distress Inventory, and the Patient Global Impression of Improvement were all completed by patients at baseline and repeated through month 24. The OPTIMAL trial had a primary outcome of surgical success as defined by anatomical success, but the primary outcome of this secondary analysis was a change in pain scale scores over 24 months after surgery. Three hundred seventy-four women participated in the original trial, with 368 in this secondary analysis. One hundred nine of the 368 women reported preoperative pain. Women with pelvic pain were more likely to be Hispanic, but there were no differences in surgical procedures performed, hospital stay, complications (ie, bladder injury, suture exposure, etc), or estimated blood loss in women with and without pelvic pain. Women with preoperative pain experienced greater pain at all time points, but also exhibited greater pain improvement at 24 months after surgery. Women with preoperative pain had worse baseline pelvic floor symptoms than those without pain. Although women with pain and women without pain had improvements in distress symptoms measured with the Pelvic Floor Distress Inventory, women with pain saw a greater improvement after surgery. All distress subscales improved significantly more in women with pain than women without pain. One additional interesting finding was that women randomized to sacrospinous suspension and pelvic muscle therapy had greater improvements in postoperative pain than those randomized to usual care. Notably, rates of surgical anatomic success and extent of Patient Global Impression of Improvement were not different between women with and without pain. Strengths of the study include its design as a secondary analysis of a large prospective multicenter randomized controlled trial. A substantial proportion of participants reported at least moderate pain at baseline but were not selected based on preoperative pain. Women in the trial were randomized to types of vaginal reconstructive surgery and pelvic muscle training, which allowed the authors to draw conclusions in categories of physical therapy treatments and surgeries for women with and without preoperative pain. Limitations of the study include a lack of preoperative pain data, pain diagnoses, and participant medications in the OPTIMAL trial. Furthermore, the study used no validated pain scale and was limited by OPTIMAL trial data collection intervals. Thankfully, data collected at numerous points over 24 months in some regard accounted for pain symptoms over time. The study found that, for patients with preoperative pain, significant improvement in pelvic floor symptoms and pain takes place after vaginal reconstructive surgery. Similar postoperative improvement rates were found. In addition, perioperative pelvic floor muscle training may be beneficial for patients with planned sacrospinous ligament fixation.

Intravesical Injection of OnabotulinumtoxinA (Botulinum Toxin Type A) in Japanese Patients With Refractory Overactive Bladder.

Botulinum toxin intravesical injection therapy (hereafter, botulinum therapy) is approved in Japan for treating urinary urgency, frequency, and urinary incontinence due to refractory overactive bladder or neurogenic bladder. Although botulinum therapy is classified as urinary incontinence surgery, it is minimally invasive, effective, and safe. However, there are few reports on the actual use of botulinum therapy and examination of its effects and side-effects. Herein, we report real-world data on botulinum therapy. Patients who received botulinum therapy for refractory overactive bladder at the Nara Medical University and affiliated facilities from May 2020 to May 2022 were enrolled. The patient background, treatment efficacy, and safety were retrospectively reviewed. Twenty-three cases of refractory overactive bladder (age: 68.4±14.1 years; 7 males, 16 females; 17 outpatient, 6 hospitalized) were enrolled. Pretreatment, the overactive bladder symptom score (OABSS) was 10.1±2.7, and post-void residual urine volume was 27.1±31.6 ml. Botulinum was administered once, twice, thrice, and four times in 11, eight, three, and one cases, respectively. OABSS decreased to 6.1±3.2 2 weeks after botulinum therapy (p<0.0001), and the effect persisted at 6.6±3.2 after 12 weeks (p<0.0001). Post-void residual urine volume increased to 74.6±79.2 ml after 2 weeks (p=0.0010), but subsequently improved to 33.9±42.0 ml after 12 weeks (p=0.0002). Adverse events included post-void residual urine volume of 200 ml or more in three patients (7.5%) and urinary retention grade 2 in two (5.0%). Botulinum therapy is effective and relatively safe for refractory overactive bladders.

Detrusor underactivity and complicated stress urinary incontinence: a cross-data study.

It is still uncertain whether detrusor underactivity (DUA) influences the outcomes of women undergoing surgery for stress urinary incontinence (SUI). Even less evidence is available about women with complicated stress urinary incontinence (C-SUI). The aim of the study was to assess outcomes of middle urethral sling (MUS) placement according to the type of SUI, and the impact of DUA on uncomplicated SUI (U-SUI) and C-SUI functional and surgical results. The study was conducted among patients undergoing MUS. The population was divided into 4 groups: 1: C-SUI with DUA; 2: C-SUI without DUA; 3: U-SUI with DUA; and 4: U-SUI without DUA. Women were qualified for the DUA group if they met one of the Jeong, Abarbanel and Marcus, BVE, and PIP1 Griffiths criteria. Post-operative functional outcomes and differences in POUR rate, de novo overactive bladder syndrome (OAB), and SUI recurrence were examined. 142 women took part in the study, of whom 97 completed the 2-year follow-up. DUA was found in 54.6% (53/97) of patients. C-SUI was prevalent also in the no-DUA group (59.1%). Post-operative ICIQ-FLUTS improved more in the no-DUA patients compared to the DUA women. Post-operative Qmax was statistically significant higher the in no-DUA than in the DUA population. After surgery, neither the PVR nor the PVR ratio differed in the DUA and the no-DUA patients. C-SUI and U-SUI patients showed a POUR rate of 15.6%-12.1%, de novo OAB 12.5%-3%, tape incision 3.1%-3%, and SUI recurrence 4.6%-3%, respectively. The impact of pre-operative DUA on the outcomes of patients undergoing MUS was negligible, even in C-SUI cases. DUA women with SUI, even if complicated, should not be excluded from this kind of surgery.

Rates of subjective and objective cure, satisfaction, and pain 10-20 years after tension-free vaginal tape (TVT) surgery: A retrospective cohort study.

To evaluate rates of subjective and objective cure, treatment satisfaction, pain, and the correlation between cure and body mass index (BMI), at 10 and 20 years after tension-free vaginal tape (TVT) surgery. Retrospective cohort study. Multicentre study including 19 units in Norway. Women undergoing TVT surgery for stress urinary incontinence (SUI) during 2001-2006 (20-year cohort) and 2011-2012 (10-year cohort). The Norwegian Female Incontinence Registry was used to identify women eligible for the study, who answered validated questionnaires about urinary incontinence, pain and satisfaction. Subjective cure of SUI (with stress index of <3, range 0-12), objective cure (<3 g on stress test) and persisting pain and satisfaction after TVT (scored on a five-point Likert scale). In total, 1210 of 1903 (64%) patients responded. The subjective cure rate was 68% after 10 years, versus 59% after 20 years, and did not significantly differ after adjusting for age, BMI, parity and preoperative stress index (adjusted OR 1.27, 95% CI 0.82-1.94). The objective cure rate was 100% versus 93% (P < 0.001), with 89% versus 76% reporting subjective satisfaction (P < 0.001), and with 4.7% versus 2.7% reporting persisting pain (P < 0.001), after 10 versus 20 years, respectively. Women in obesity classes I and II, compared with women of normal weight, had an increased risk of not being subjectively cured (crude OR 2.02, 95% CI 1.42-2.90; OR 2.95, 95% CI 1.60-5.46, respectively). Tension-free vaginal tape (TVT) provided high rates of subjective and objective cure at 10 and 20 years after surgery, with no significant difference between the two cohorts. Although 3%-5% of women experienced persisting pain, most women were satisfied with TVT surgery. Obesity was associated with a lower cure rate.

Risk factors for 5-year complications after midurethral sling surgery for stress urinary incontinence: a retrospective cohort study from Taiwan

Midurethral sling surgery is the current gold standard worldwide for stress urinary incontinence (SUI) surgery, with over 90% of surgeons worldwide using the midurethral sling for SUI between 2008 and 2018. However, concerns surround mesh-related adverse events associated with the midurethral sling. The decision to use the midurethral sling for surgical treatment has become a challenging one for clinicians, surgeons and patients. We sought to determine the factors for 5-year complications after midurethral sling surgery, to improve the clinical decision-making process. Records were reviewed from a total of 1961 female patients who underwent their first midurethral sling surgery for SUI between 2003 and 2018 at a single teaching hospital in Taiwan. A multivariable Cox proportional hazard model calculated the hazard ratios of risk factors for surgical complications, after adjusting for confounders. Surgical complications (i.e., secondary surgery and urinary retention) occurred in 93 (4.7%) patients within 5 years following the index operations. These patients were more likely to be older, to have a history of menopausal syndrome within 1 year prior to the index operation, a medication history of oral antidiabetic drug use, hormone replacement therapy (HRT), slower average flow rate, and longer voiding time compared with patients without surgical complications. In the multivariate analysis, HRT (adjusted hazard ratio, 1.787; 95% confidence interval, 1.011–3.158, p = 0.04) was significantly associated with surgical complications at 5 years, after adjusting for age, gender, diabetes, menopause syndrome, average flow rate, and sling type. Our findings suggest that a medication history of HRT may be a risk factor associated with surgical complications, especially urinary retention, at 5 years in women undergoing midurethral sling surgery for SUI.

Hemoglobin A1c and Reoperation After Surgery for Stress Incontinence or Prolapse.

Few studies compare the link between hemogobin A1c (HbA1c) and urogynecologic surgical complications. The objective of this study was to determine the association between HbA1c and reoperation in women undergoing surgery for stress urinary incontinence (SUI) or pelvic organ prolapse (POP). We performed 2 separate retrospective cohort analyses using Cerner's HealthFacts Database (750 hospitals; 519,000,000 patient encounters from January 1, 2010, to November 30, 2018). We included women undergoing surgery for (1) SUI or (2) apical POP by International Classification of Diseases coding who had HbA1c at the initial procedure. Each analysis compared those undergoing reoperation for complications or recurrence and those who did not. Multivariable logistic regression assessed the association between reoperation and HbA1c both as a continuous variable and comparing the commonly accepted cutoff ≥8. Of 30,180 SUI surgical procedures and 26,389 POP surgical procedures, 1,625 (5.4%) and 805 (3.1%) had HbA1c. Median (interquartile range) HbA1c in grams per deciliter was similar by reoperation status (SUI: 6.0 [5.6-6.8] vs 6.1 [5.6-6.9], P = 0.35; POP: 6.2 [5.6-6.6] vs 6.1 [5.7-6.8], P = 0.60). Reoperation was also similar using the HbA1c ≥8% cutoff (SUI: 6.9% vs 7.4%, P = 0.79; POP: 6.3% vs 5.4%, P = 0.77). On multivariate analysis, HbA1c value was not a significant predictor of reoperation either as a continuous (SUI: odds ratio [OR] = 0.966, 95% CI = 0.833-1.119; POP: OR = 1.040, 95% CI = 0.801-1.350) or dichotomous variable ≥8 (SUI: OR = 0.767, 95% CI = 0.407-1.446; POP: OR = 0.988, 95% CI = 0.331-2.951). Mean follow-up was 4.28-5.13 years. Although other studies have shown a link between diabetes and complications, we were unable to show an association between HbA1c values and rates of reoperation.

Serious complications and recurrences after retropubic vs transobturator midurethral sling procedures for 2682 patients in the VIGI-MESH register

BackgroundMidurethral slings are the gold standard for treating stress urinary incontinence, but their complications may raise concerns. Complications may differ by the approach used to place them. Objective(s)To compare serious complications and reoperations for recurrence after midurethral sling procedures by the retropubic and transobturator routes for female stress urinary incontinence. Study DesignThis analysis covers patients included in the French multicenter VIGI-MESH register since February 2017 who received a midurethral sling for female stress urinary incontinence by the retropubic or transobturator route, excluding single-incision slings. Follow-up continued to October 2021. Serious complications (Clavien-Dindo classification ≥ Grade III) imputable to the midurethral sling and reoperations for recurrence were compared by Cox proportional hazard models including any associated surgery (hysterectomy or prolapse) and a frailty term to consider the center effect. Baseline differences were balanced by propensity score weighting. Analyses using the propensity score and Cox models were adjusted for baseline differences, center effect, and associated surgery. Results1830 participants received a retropubic sling and 852 a transobturator sling in 27 French centers, placed by 167 surgeons. The cumulative two-year estimate of serious complications was 5.8% (95% CI 4.8%-7.0%)) in the retropubic group and 2.9% (95% CI, 1.9%–4.3%) in the transobturator group, that is, after adjustment, half that of the retropubic group (adjusted HR 0.41; 95% CI 0.3-0.6). The cumulative two-year estimate of reoperation for recurrence of stress urinary incontinence was 2.7% (95% CI 2.0-3.6) in the retropubic group and 2.8% (95% CI 1.7-4.2) in the transobturator group, with risk of revision for recurrence higher in the transobturator group after adjustment (adjusted HR 1.9; 95% CI 1.2-2.9); this surplus risk disappeared after exclusion of the patients with a previous surgery for stress urinary incontinence. ConclusionsThe transobturator route for midurethral slings is associated with a lower risk of serious complications but a higher risk of surgical reoperation for recurrence than the retropubic route. Despite the large number of surgeons involved, these risks were low. The data are therefore reassuring.

Which parameters, related to the female urethra and pelvic floor, determine therapy selection for recurrent female stress urinary incontinence: ICI‐RS 2023?

AbstractIntroductionThe evidence basis for therapy selection in women who have failed primary stress urinary incontinence (SUI) surgery is limited. The ICI‐RS group discussed the available data at its meeting in June 2023, particularly the anatomical characteristics as assessed using magnetic resonance imaging (MRI) and ultrasound (US) modalities, functional characteristics associated with storage and voiding urodynamic assessment, as well as the patient characteristics that might influence outcomes. This paper summarizes the evidence base that supported these discussions and offers the basis for research proposals for future groups.MethodsA literature search of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials was performed, and the data is presented. Research questions are based on the knowledge gaps highlighted.ResultsPossible MRI parameters that may influence outcomes were striated urethral sphincter volume, bladder and proximal urethral funneling, pubo‐urethral ligament integrity, distance of the bladder neck below the pubococcygeal line, posterior urethra‐vesical angle, and bladder neck to levator ani distance. US parameters included sling distance to the urethral lumen and pubis, sling position, bladder neck mobility, and lateral arm asymmetry, twisting, or curling. Urodynamic parameters included detrusor overactivity, Valsalva leak point pressure, maximum urethral closure pressure, and bladder outlet obstruction. Important patient parameters included body mass index, age, and previous interventions.ConclusionsIdentifying and quantifying causative factors in patients with recurrent SUI, that allow clinicians to modify subsequent treatment choices and techniques may help reduce treatment failure and complications. Formulating algorithms is the next step in optimizing patient counseling, surgical selection, and healthcare allocation.

Comparison of midurethral tape with autologous rectus fascial sling surgery for stress urinary incontinence: A systematic review and meta-analysis

Abstract Objectives To compare the success rates of autologous fascial mesh (sling and transobturator tape [TOT]) with midurethral synthetic meshes (tension-free vaginal tape sling [TVT] and TOT) for stress urinary incontinence. Materials and methods A literature search for studies published in English was conducted from May 10, 2022, to June 1, 2022. The search included MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Google Scholar, and ProQuest, using the terms{“Autologous fascial slings”}OR {“AFS”} AND{“TOT”} OR {“Transobturator tape”} OR{“TVT”} OR{“Transvaginal tape”}. A total of 20 studies, including 10 randomized controlled trials, were selected for the review. RevMan software (version 5.3) was used to calculate the pooled effect estimates for operative and postoperative variables. Results In the systemic review, 20 studies, including 10 randomized controlled trials, were assessed. In the TVT versus autologous pubovaginal sling (A-PVS) groups, the effect estimates for the surgical duration, catheter duration, success, and complication rates were more advantageous for TVT. However, in comparison to autologous transobturator tape groups, TOT provided better operative time and a shorter hospital stay. Moreover, in comparison to the A-PVS group, the TOT group was superior in terms of operating time, urethral catheterization, hospital stay, amount of residual urine, and wound complications. The A-PVS group had significantly more groin and thigh pain. Conclusions During medium- and long-term follow-ups, the use of autologous rectus fascia grafts using a A-PVS or TOT provided similar complication rates and urinary continence results as using midurethral synthetic meshes (TVT and TOT).

Cost-Utility Analysis of Midurethral Sling Timing Among Women Undergoing Prolapse Surgery

(Abstracted from Urogynecology 2023; doi: 10.1097/SPV.0000000000001384) Approximately 25% of women in the United States are affected by pelvic floor disorders, with estimates pointing to a 50% increase in urinary incontinence prevalence and pelvic organ prolapse (POP) by 2050. Surgery for stress urinary incontinence (SUI) is also often required, which adds to economic burdens of pelvic floor disorders. Determining the POP patients who would benefit most from concomitant midurethral slings (MUSs) remains a clinical challenge.

Bibliometric analysis of studies on stress urinary incontinence surgery

BackgroundStress urinary incontinence (SUI) is characterized by the involuntary leakage of urine during activities that increase abdominal pressure. In recent years, a considerable number of studies on SUI surgery have been published. However, there has been a lack of systematic quantification and comprehensive summarization of these studies. Bibliometrics is a discipline that utilizes measurement methods to quantify scientific literature. Thus, this study utilized publications from the Web of Science (WOS) as a data source and conducted a comprehensive analysis and visualization of studies related to SUI surgery in recent years using bibliometric techniques. MethodsWe conducted a search and retrieved information on 988 studies related to SUI surgery in the WOS Core Collection. The data covered ten years from September 7, 2013, to September 7, 2023. We employed VOSviewer software, CiteSpace software, and Bibliometrix for analysis and visualization. ResultsOver the ten years, the number of publications exhibited a fluctuating trend, initially decreasing and then increasing. The United States emerged as the leading contributor in terms of both publication volume and quality. The University of Alabama Birmingham ranked as the institution with the highest number of publications, while the International Urogynecology Journal featured the most publications among journals. ConclusionsThis paper presents a bibliometric analysis of publications related to SUI surgery from 2013 to 2023. The aim is to offer researchers a concise overview of the field and inspire future research directions.

Urinary Tract Infections After Urogynecologic Surgery: Risk Factors, Timeline, and Uropathogens

ABSTRACT Postoperative urinary tract infection (PO-UTI) is seen in 6.4%–32% of stress urinary incontinence (SUI) and/or pelvic organ prolapse (POP) surgeries despite perioperative antibiotic prophylaxis. Postoperative complications associated with PO-UTI include increased mortality and longer hospitalization. Increasing prevalence of resistance to antibiotics and antibiotic stewardship principles necessitate both the improvement of infection prevention strategies and judicious antibiotic prescriptions. Four factors are known to increase PO-UTI risk: (1) recurrent UTI (RUTI) history, (2) preoperative UTI, (3) day-of-surgery UTI, and (4) prolonged postoperative catheterization. This study intended to determine (1) risk factors of PO-UTI and PO-RUTI, (2) preoperative and postoperative UTI temporal distribution, and (3) detected uropathogens in a large database. The study used medical record data of all SUI/POP surgical procedures performed in the Kaiser Southern California Hospital system from January 1, 2008 to December 31, 2016 for women 18 years of age or older. Procedures used Current Procedural Terminology codes for identifying and subcategorizing surgical procedures and their route (SUI or POP; abdominal or vaginal, respectively). The study-wide definition of UTI was as follows: (1) positive standard urine culture of greater than 105 CFU/mL of ≤2 uropathogens, or (2) prescription of urinary antibiotics prescribed for the indication of UTI symptoms. The analysis consisted of 21,063 urogynecologic surgical procedures performed on 20,051 women (33,626 POP and/or SUI procedures), with 22,641 UTI events being diagnosed in 10,091 women. Mean age was 56.9 years, and mean BMI was 29.1. The cohort underwent surgery for only SUI (35.4%), only POP (32.7%), or POP/SUI combined (31.9%). In the 13.5 months postoperatively, 11,976 UTIs were diagnosed in 6733 women. The first month experienced a sharp increase compared with the preoperative year, the second month increased further, and the third month showed leveling of PO-UTI incidence. Prescribed antibiotics captured most UTI events (13,337 or 58.3%). Prescribed antibiotics, in order of most-prescribed to least-prescribed, were as follows: ciprofloxacin (33.7%), cephalexin (21.4%), nitrofurantoin (20.4%), and sulfamethoxazole-trimethoprim (17.6%). The study determined that most PO-UTIs occurred within the first 2 months, with many of these being diagnosed within 2 weeks of surgery. For those patients already having a history of RUTI, RUTI significantly increases in postoperative year 1 when compared with the preoperative year. All patients undergoing SUI procedures had increased PO-RUTI risks compared with their POP-only group peers. Escherichia coli was the most common pathogen found. Risk and event timing were affected by surgical indication: although surgery for only SUI had a lower 6-week PO-UTI risk, it was counterintuitively associated with a higher PO-RUTI risk. Multivariate regression revealed predictable risk factors for PO-UTI: OAB, history of diabetes, history of preoperative UTI within 6 weeks of surgery, history of RUTI, stent and catheter placement. A more confusing finding was the association of a vaginal estrogen prescription with increased short-term PO-UTI risk, possibly related to its use in women with a history of RUTI, but more probably related to the postmenopausal status of many of the women in the dataset. The study recommends preoperative assessment with the purpose of identifying and eliminating UTIs within 6 weeks before surgery, as well as development of protocols for enhanced prophylaxis for women at increased risk such as diabetics and women with preoperative RUTI.

The Diagnostic Accuracy of a Retrograde Voiding Trial for Restoration of Spontaneous Voiding Function after Prolapse and Urinary Incontinence Surgery

To assess the diagnostic accuracy of a retrograde voiding trial for the restoration of spontaneous voiding function after prolapse and urinary incontinence surgery and thereby determine whether the retrograde method can be a reliable alternative to the spontaneous voiding trial. A retrospective cohort study. A single tertiary hospital in South Korea. Women who underwent operations for prolapse, urinary incontinence, or both. Sequential voiding trials on postoperative day 1 or 2-retrograde voiding trial followed by spontaneous voiding trial. Of the 408 women analyzed, 278 (68.1%) passed the spontaneous voiding trial on the first day of assessment and none experienced urinary retention after a successful voiding trial. Receiver operating characteristic analyses of retrograde voiding trials evaluating voided volume (VV), postvoid residual (PVR), and voiding efficiency (VE) all demonstrated high diagnostic accuracy for restoration of spontaneous voiding function, whereas measuring PVR and VE had better discriminative ability than VV (area under the curve [95% confidence interval]=0.93 [0.90-0.95] for PVR, 0.94 [0.91-0.96] for VE, and 0.88 [0.85-0.91] for VV; DeLong's test between PVR/VE and VV p < .01). The optimal cutoffs determined by the Youden index were 200 mL for VV (sensitivity 85.0%, specificity 78.0%), 100 mL for PVR (sensitivity 84.0%, specificity 87.0%), and 66.7% for VE (sensitivity 86.0%, specificity 88.0%). The retrograde voiding trial is an accurate predictor for restoration of spontaneous voiding function after prolapse and incontinence surgery and can be a useful alternative to the spontaneous voiding trial.

Is Surgical Treatment for Obesity Able to Cure Urinary Incontinence in Women?-A Prospective Single-Center Study.

There is enough evidence to support weight loss in order to improve urinary incontinence. Nevertheless, weight loss and maintaining a lower weight are not easy to achieve in the general population. Our study aims to evaluate whether bariatric surgery has a positive effect on the symptoms of urinary incontinence in female patients. We performed a prospective study on obese female patients before and after bariatric surgery, over a period of 9 years. Patients with a BMI ≥ 33 kg/m2 were included if they described involuntary loss of urine and no previous surgery for urinary incontinence was performed. The patients underwent laparoscopic surgery, either gastric sleeve, bypass or banding, performed by four surgeons in our hospital. The type of incontinence was not assessed at the initial visit carried out by the surgeon. All patients who declared being incontinent were referred to the urologist where they received the ICIQ-UI-SF questionnaire before their bariatric surgery and during follow -up visits. The sum of points obtained at questions 3, 4 and 5 was used to evaluate the severity of incontinence, as well as the impact on the quality of life. Our evaluation collected data on age, time since onset of symptoms, pad usage, number and type of deliveries, concomitant conditions and medications. The type of incontinence was assessed by the urologist before bariatric surgery as urge, stress or mixed incontinence. At follow-up visits, the patients were also asked to fill out a 10-point VAS questionnaire evaluating their perception on the evolution of incontinence symptoms. Data were analyzed using t-test statistical analysis. Our objective defined changes in incontinence as cure, improved, no change and worse. We included 54 women from whom initial data and at least 18 months of follow-up were available. We observed that about 50% of all women undergoing bariatric surgery have some degree of urinary incontinence. The ICIQ score improved from 13.31 ± 5.18 before surgery to 8.30 ± 4.49 points after surgery (p < 0.0001). Before surgery, 38 patients (70%) described severe incontinence compared to only 20 patients (37%) after surgery. A total of 16 women (31%) reported complete cure of urinary incontinence after bariatric surgery. Data from the VAS questionnaire show improvement in 46 cases (85%). Pad usage improved from 7.04 ± 2.79 to 3.42 ± 2.77 (p < 0.001) per day. The number of patients using more than one pad per day decreased from 35 (65%) to 9 (17%). The type of incontinence did not seem to be relevant, but our sample size was too small to lead to statistically significant results. There was no impact on the outcome of incontinence of number/type of delivery, age or BMI. Our data show that bariatric surgery is able to cure urinary incontinence in one of three obese women. A significant improvement was obtained in more than two-thirds of the patients, regardless of the type of incontinence. For an obese female with urinary incontinence, treatment for obesity should prevail and incontinence should be treated only if symptoms remain.

A robot-assisted laparoscopic revision of an artificial urinary sphincter in a patient with spinal cord injury.

This step-by-step article demonstrates our approach to robot-assisted laparoscopic revision of a bladder neck sited artificial urinary sphincter (AUS) for a spinal cord injured patient. The bladder neck location of an AUS in the spinal cord injured demographic is ideal to minimise urethral complications and urinary tract infections, whilst the transabdominal approach reduces the risk of wound breakdown that can occur via the typical perineal incision for AUS insertion. The accompanying video will guide viewers as to our minimally invasive technique for cuff revision in the event of secondary surgery for recurrent urinary incontinence.

Retropubic tape surgery for stress urinary incontinence: can women be cured without voiding dysfunction?

Retropubic tension free vaginal tape (RP-TVT) has become the gold standard for surgical management of female stress urinary incontinence but is associated with voiding dysfunction (VD). We developed for more than 10years a reproductible and totally tension free tape procedure. Our goal is to determine efficiency of this technique compared to the incidence of VD. We retrospectively reviewed patients who underwent RP-TVT in our center between 2011 and 2019. Subjective cure, VD (determined as maximum urinary flow rate (Qmax) < 15mL/s or post void residual (PVR) volume > 150mL, or tape's section or resection requirement for underactive bladder (UB) with significant PVR) was assessed at 1year. The main objective was the evaluation of subjective cure and VD at 1year. On the 319 patients reviewed, 93% of the patients were dry and 10.9% presented VD at one year. UB (OR = 5.01 [1.55-16.44], p = 0.008), preoperative Qmax < 15mL/s (OR = 0.89 [0.84-0.95], p = 0.001) and previous incontinence surgery (OR = 4.20 [1.54-11.46], p = 0.005) were associated with VD. Acute urinary retention concerned 4.7% of the population and all were resolved after 6weeks postoperatively. We reported 0.3% of de novo urgency and patients without VD showed a significant decrease of their voiding time at 1year. The placement of RP-TVT without intraoperative tightening seems to be a safe technique ensuring a high cure rate and low occurrences of bladder outlet obstruction.

Is detrusor underactivity associated with voiding dysfunction after single incision sling surgery?

Some women experience voiding dysfunction after stress urinary incontinence (SUI) surgery. We explore if detrusor underactivity (DU) found in urodynamic study (UDS) prior to SUI surgery using an adjustable single incision sling (SIS) may be related to voiding dysfunction after surgery. This is a prospective, diagnostic, transversal, single center study comparing voiding dysfunction after SUI surgery with a SIS (Altis®; Coloplast, Humlebæk, Denmark) between women with DU (cases) or normal detrusor (controls). Inclusion criterium was women ≥18 years with SUI/mixed UI (stress predominant) operated between June 2013 and December 2020. Exclusion criteria were: women without UDS prior to surgery or without voiding phase in the P/Q, previous incontinence surgery, POP stage ≥2, neurogenic conditions, other pelvic floor surgery. Urinary symptoms were assessed using structured questions evaluating storage/voiding symptoms. Patients were divided into two groups according to projected Isovolumetric Pressure Index (PIP<inf>1</inf>) with 30-75 cmH<inf>2</inf>O indicating normal contractility. A total of 139 women were included, 29 (20.9%) in DU group and 110 (79.1%) in control group. Control and DU groups have shown similar objective (75.5% vs. 71.4% P=0.66) and subjective (85.4% vs. 96.1% P=0.22) success rates, respectively, without statistical differences. Voiding symptoms increased after surgery in both groups (+20.7% DU group vs. +8.1% normal group, P=0.29). More voiding symptoms (persistent/de novo) were found in DU group vs. normal group, but without statistically significant differences. According to our results, the presence of DU previous to SUI surgery with a SIS (Altis®, Coloplast) has no impact on objective and subjective success rates. On the other hand, patients with preoperative DU showed higher proportion of voiding dysfunction but no statistical difference.
