Comparing Postoperative Urinary Retention Rates Between Robotic Apical Prolapse Repairs.

Understanding the risk of urinary retention with different prolapse repair surgical procedures is important for perioperative counseling. The study compared postoperative urinary retention rates between robotic sacrocolpopexy and robotic uterosacral ligament suspension. This institutional review board-exempt retrospective cohort study compared patients who underwent pelvic organ prolapse repair with robotic sacrocolpopexy (RSCP) and robotic uterosacral ligament suspension (RUSLS) between June 2018 and March 2022. Our primary outcome was the rate of acute postoperative urinary retention (POUR) in these groups. Secondary outcomes were the number of days needed to resolve urinary retention and persistent voiding dysfunction. Out of 298 patients, 258 underwent RSCP and 40 underwent RUSLS. Acute POUR was found in 73 patients (24%): 46 patients (18%) in the RSCP group versus 26 patients (65%) in the RUSLS group (P < 0.001). Multivariate analysis demonstrated a significantly higher rate of acute POUR after RUSLS (odds ratio [OR] = 17.92, confidence interval [CI] = 3.06-104.86; P = 0.001). Patients with an elevated preoperative postvoid residual volume >100 mL or concomitant midurethral sling were more likely to develop POUR (OR = 2.93, CI = 1.43-5.98; P = 0.003 and OR = 2.19, CI = 1.16-4.14; P = 0.016, respectively). While patients with higher parity were less likely to have urinary retention (OR = 0.71, CI = 0.53-0.96; P = 0.024), age, body mass index, prolapse stage, and concurrent posterior repair did not affect the urinary retention rate significantly. The number of days needed to resolve POUR and persistent voiding dysfunction were similar. Acute POUR appears more likely to develop after RUSLS compared to RSCP. Elevated preoperative postvoid residual volume and concomitant midurethral sling surgery independently increase the risk of POUR.

Use of sugammadex in prevention of post-operative urinary retention in minimally invasive hernia surgery.

Post-operative urinary retention (POUR) is a known complication of hernia surgery. Minimally invasive inguinal hernia repair (IHR) is typically done under general anesthesia with neuromuscular blockade (NMB), which is commonly reversed with an anticholinesterase inhibitor paired with an anticholinergic agent. Sugammadex is a unique NMB reversal agent that does not have to be paired with an anticholinergic. We sought to explore the role of sugammadex in reducing the rate of POUR following these procedures. Data were collected retrospectively at a single institution between February 2016 and October 2019. We identified and studied patients who underwent minimally invasive IHR and received either sugammadex or neostigmine/glycopyrrolate for NMB reversal. The primary endpoint was POUR requiring bladder catheterization. Secondary endpoints included post-operative and 30-day readmissions. 274 patients were included in this study (143 received neostigmine and glycopyrrolate, 131 sugammadex). The sugammadex patients were on average 5years older than the neostigmine/ glycopyrrolate patients (63.2 vs 58.2, p = 0.003), and received less median intravenous fluids (IVF) (900ml vs 1000ml; p = 0.015). There was a significant difference in the rate of POUR between the sugammadex and neostigmine/glycopyrrolate patients (0.0% vs 8.4%, p ≤ 0.001). The difference remained significant after controlling for age and IVF. The odds of POUR for those who received neostigmine/glycopyrrolate were 25 × higher than the odds of those who received sugammadex. The results of this study reflect the protective role of sugammadex against POUR in minimally invasive IHR cases.

Surgical outcomes of endoscopic enucleation of the prostate in community aging males with or without preoperative urinary retention.

This study aims to investigate the surgical outcomes of endoscopic enucleation of the prostate in older males with or without preoperative urinary retention (UR). We conducted a study on selected patients with symptomatic benign prostatic hyperplasia (BPH) who underwent either thulium:YAG laser (vela XL) prostate enucleation (ThuLEP) or bipolar plasma enucleation of the prostate (B-TUEP) at the geriatric urology department of our institution. The studied patients were categorized into two groups, namely the UR group and the non-UR group, on the basis of whether they experienced UR in the 1month preceding their surgery. Their clinical outcomes following prostate endoscopic surgery were evaluated and analyzed. Our results revealed comparable outcomes for operation time, length of hospital stay, percentage of tissue removed, re-catheterization rate, and urinary tract infection rate within the 1month between the B-TUEP and ThuLEP surgery groups, regardless of UR history. However, the non-UR B-TUEP group experienced more blood loss relative to the non-UR ThuLEP group (P = .004). Notably, patients with UR exhibited significantly greater changes in IPSS total, IPSS voiding, and prostate-specific antigen values relative to those without UR. Both ThuLEP and B-TUEP were effective in treating BPH-related bladder outlet obstruction. Our study identified more pronounced changes in IPSS total, IPSS voiding, and prostate-specific antigens within the UR group. Moreover, the rate of postoperative UR in this group was not higher than that observed in the non-UR group. Our study also revealed that the presumed benefits of laser surgery in reducing blood loss were less pronounced for patients with UR.

1136 Risk Factors for Postoperative Urinary Retention After Deep Brain Stimulation Surgery: The Role of the Subthalamic Nucleus

INTRODUCTION: Deep brain stimulation (DBS) is a widely used neurosurgical procedure for treating Parkinson's disease (PD) and essential tremor (ET). Lower urinary tract dysfunction is a common complication in PD, and this study examines the risk factors for postoperative urinary retention (POUR) after DBS surgery in PD and ET patients to improve patient outcomes. METHODS: This retrospective study analyzed data from patients who underwent DBS surgery for PD and ET at the University of Florida between 2010 and 2021. Data on patient characteristics and surgical details were collected and analyzed using univariate and mixed-linear models. RESULTS: 350 patients underwent 1086 DBS or IPG surgeries, with 153 of them having PD and 197 having ET. The rate of POUR was 79/477 (16.6%), 19/295 (5.2%), and 1/246 (0.4%) for Part 1, Part 2, and IPG replacement. Optimal mixed linear modeling revealed history of urinary retention (OR = 10.2, p = .002), Part 1 surgery (OR = 3.6 compared to Part 2, p &lt; .0003), male sex (OR = 2.5, p = .011), having an electrode placed or connected for the first time (OR = 1.8, p = .046), surgical time (OR 1.5 for each 30 min increase, p &lt; .0001), CCI (OR = 1.4 per comorbidity, p= .006), and preoperative opioid use (OR 1.4 for each additional 10 MME, p = .022) to be significant risk factors for POUR. Having an electrode in STN was found to be protective of POUR (OR = 0.4, p = .030). CONCLUSIONS: While most identified risk factors for POUR in DBS are non-modifiable, they remain important for preoperative planning. Reducing opioid use and minimizing surgical time may help mitigate POUR risk. Targeting the STN during DBS may lead to decreased POUR rates, indicating the potential benefits of STN-targeted DBS for PD and ET patients.

Preoperative Bladder Scanning Can Predict Postoperative Urinary Retention Following Total Joint Arthroplasty.

As total joint arthroplasty (TJA) moves to the outpatient setting, it is becoming clear that postoperative urinary retention (POUR) is a potential impediment to same-day discharge. Although risk factors for POUR have been widely studied, the lack of their clinical utility warrants investigation of specific preoperative factors that can assist in surgical planning and patient optimization. The purpose of the current study was to determine whether preoperative symptom surveys and bladder scanning are useful tools in identifying POUR risk. We performed a prospective analysis of patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) at a high-volume orthopaedic hospital between December 1, 2020, and September 30, 2021. A total of 507 patients (324 female and 183 male) undergoing TJA completed the American Urological Association (AUA) symptom index preoperatively and then again at 14 and 64 days postoperatively. Post-void bladder scans were obtained in the immediate preoperative setting. POUR was defined as a bladder volume of >500 mL that required catheterization. Chi-square and quintile analysis were used to compare bladder scanning volumes, and Student t tests were used to compare AUA scores. The rate of POUR was 37% (66 female and 34 male) and 23% (37 female and 19 male) in the TKA and THA groups, respectively. Increasing post-void residual volume (PVRV) measured on preoperative bladder scanning was found to be predictive of POUR. Among the TKA cohort, younger age and lower body mass index were also associated with increased catheterization, although age was not statistically significant. The AUA symptom survey was not found to correlate with POUR in either population. There was a predictable and exponential increase in the rate of catheterization as preoperative PVRV increased from 50 to 200 mL. The AUA symptom score showed no utility in predicting POUR in our study population. We propose that preoperative bladder ultrasonography become standard practice in TJA, especially among patients scheduled for same-day discharge. Prognostic Level II .

Risk factors for postoperative urinary retention after deep brain stimulation surgery: the role of the subthalamic nucleus.

Deep brain stimulation (DBS) is a common procedure in neurosurgery used for the treatment of Parkinson's disease (PD) and essential tremor (ET) among other disorders. Lower urinary tract dysfunction is a common complication in PD, and this study aimed to evaluate the risk factors of postoperative urinary retention (POUR) after DBS surgery in patients with PD compared with patients with ET. Understanding the risk factors associated with this complication may help in the development of strategies to minimize its occurrence and improve patient outcomes. The study was a retrospective analysis of patients who underwent DBS surgery for PD and ET at the University of Florida between 2010 and 2021. The surgical technique used has been described in previous articles and included a two-stage procedure, with stage 1 involving burr hole placement, microelectrode recording, and electrode implantation and stage 2 involving the placement of an implantable pulse generator (IPG). Data were collected on patient characteristics and surgical details and analyzed using univariate and mixed-linear models. Post hoc propensity score matching was used to confirm the association between subthalamic nucleus (STN)-DBS and POUR. The study included 350 patients (153 with PD and 197 with ET) who underwent 1086 DBS surgeries (lead implantations, IPG placement, and IPG replacements). The POUR rates were 16.6% (79/477), 5.2% (19/363), and 0.4% (1/246) for stage 1, stage 2, and IPG replacement procedures, respectively. Optimal mixed-effects logistic modeling revealed history of urinary retention (OR 9.3, p = 0.004), male sex (OR 2.7, p = 0.011), having an electrode placed or connected for the first time (OR 2.2, p = 0.014), anesthesia time (OR 1.5 for each 30-minute increase, p < 0.0001), preoperative opioid use (OR 1.4 for each additional 10 morphine milligram equivalents, p = 0.032), and Charlson Comorbidity Index (OR 1.4 per comorbidity, p = 0.017) to be significant risk factors for POUR. Having an electrode in the STN was found to be protective of POUR (propensity score-matched analysis: OR 0.2, p = 0.010). Most risk factors found to increase the risk of POUR in DBS are not modifiable but are still important to consider in preoperative planning. Opioid use reduction and shorter anesthesia time may be modifiable risk factors to weigh against their alternative. Targeting the STN during DBS may result in decreased rates of POUR. This highlights the potential for STN-targeted DBS in reducing POUR risk in PD and ET patients.

Effect of neuromuscular blockade reversal on post-operative urinary retention following inguinal herniorrhaphy.

This study aims to define the risk of post-operative urinary retention (POUR) following inguinal hernia repair in those that received sugammadex compared to anticholinesterase. Adults undergoing inguinal herniorrhaphy from January 2019 to July 2022 with at least 30-day follow-up receiving rocuronium or edrophonium and reversed with an anticholinesterase or sugammadex were included. 1-to-2 propensity score matched models were fitted to evaluate the treatment of effect of sugammadex vs. anticholinesterase on POUR, adjusting for patient comorbidities, ASA class, wound class, operative laterality, urgency of case, and open versus minimally invasive repair. 3345 patients were included in this study with 1101 (32.9%) receiving sugammadex for neuromuscular blockade reversal. The 30-day rate of POUR was 2.8%; 1.4% in the sugammadex and 4.4% in the anticholinesterase group. After propensity score matching, patients receiving sugammadex had significantly lower risk of POUR compared to anticholinesterase overall (OR 0.340, p < 0.001, 95% CI 0.198-0.585), in open (OR 0.296, p = 0.013, 95% CI 0.113-0.775) and minimally invasive cases (OR 0.36, p = 0.002, 95% CI 0.188-0.693), unilateral (OR 0.371, p = 0.001, 95% CI 0.203-0.681) and bilateral repairs (OR 0.25, p = 0.025, 95% CI 0.074-0.838), elective (OR 0.329, p < 0.001, 95% CI 0.185-0.584) and clean cases (OR 0.312, p < 0.001, 95% CI 0.176-0.553). The incidence of 30-day new onset POUR was 2.8%. Sugammadex was associated with significantly lower risk of POUR after inguinal herniorrhaphy compared to anticholinesterase overall and when stratifying by operative modality, laterality, and wound class.

Effectiveness and safety of ultra-low-dose spinal anesthesia versus perineal blocks in hemorroidectomy and anal fistula surgery: a randomized controlled trial

BackgroundUltra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). MethodsA two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. ResultsFifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). ConclusionSA and PB are similarly effective in pain control during the first 48 h after hemorrhoidectomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Rate of Postoperative Urinary Retention after Anterior Compartment Prolapse Surgery: A Randomized Controlled Trial Comparing Early versus Conventional Transurethral Catheter Removal.

Pelvic organ prolapse is a common condition of pelvic floor dysfunction in women, especially in adult vaginally parous and elderly women. Because of its anatomy, the anterior compartment has a significant effect on urinary symptoms. Anterior colporrhaphy and colpocleisis are major anterior compartment prolapse-related surgeries. As we know, postoperative urinary retention (POUR) is one of the most common complications following pelvic floor surgery. To prevent this complication, indwelling bladder catheterization is routinely applied. In contrast, to minimize risk of infection and the patient's discomfort, the catheter should be removed as soon as possible. However, there is a lack of clarity regarding the optimal timing for catheter removal. Therefore, the aim of this trial is to compare the rate of POUR after anterior prolapse surgery between early transurethral catheter removal (24 h postoperatively) and our standard practice (on postoperative day 3). We conducted a randomized controlled trial among patients undergoing anterior compartment prolapse surgery between 2020 and 2021 at a university hospital. Women were randomized into two groups. After removal, if the second void residual urine volume exceeded 150 mL, POUR was diagnosed, and intermittent catheterization was performed. The primary outcome was the POUR rate. The secondary outcomes included urinary tract infection, asymptomatic bacteriuria, time to ambulation, time to spontaneous voiding, length of hospitalization, and patient satisfaction. Analysis was performed according to the intention to treat principle. The calculated sample size was 68 patients (34 patients in each group) for a 95% confidence interval, 80% power, 5% probability of type I error, and 10% data loss. This study demonstrated that early catheter removal was comparable in POUR rate to conventional treatment with shorter hospitalization among patients undergoing anterior compartment prolapse surgery. Additionally, we observed no re-hospitalization owing to POUR. Therefore, early transurethral catheter removal is preferable following anterior compartment prolapse-related surgery.

Prophylactic alpha-blockade for prevention of post-operative urinary retention after inguinal hernia repair: a systematic review and meta-analysis.

The rate of post-operative urinary retention (POUR) in inguinal hernia repairs (IHR) is estimated to be approximately 5.9% to 38% worldwide. Currently, there are minimal studies on the prophylaxis of POUR after IHR. Pre-operative administration of alpha-blockers such as (but not limited to) Tamsulosin, Prazosin and Alfuzosin has shown promising results in the prevention of POUR in patients undergoing IHR. This study aims to determine the effectiveness of prophylactic alpha-blockade in the prevention of POUR after IHR. This study reports the findings of a systematic review and meta-analysis. Randomised controlled trials (RCTs) using prophylactic alpha-blockade for the prevention of POUR after open and/or laparoscopic IHR in patients aged more than 18years in all sex groups were included. Multiple databases were searched from inception to October 2021 using the PRISMA flow diagram. Data were extracted and analysed to include eligibility criteria, comparator, intervention, study and participant characteristics. Studies excluded were non-RCT studies and patients with known urinary tract disorders such as benign prostate hypertrophy, urinary incontinence and cancer of the bladder or prostate. Subgroup analyses were also conducted. All effect measures of each data were odds ratio with 95% confidence interval. All studies were pooled using the dichotomous random effects Mantel-Haenszel statistical mode and I2 was used to assess heterogeneity. Publication bias was detected using the Cochrane risk-of-bias tool for randomised trials (RoB-2) involving two independent reviewers. A total of eight RCTs were identified which provided adequate numeric data for incorporation into the meta-analysis. Overall, administration of pre-operative alpha-blocker prior to IHR did not prevent POUR (95% CI 1.20 (0.96-1.49), I2: 34%). Subgroup analysis comparing pre-operative use of prophylactic alpha-blocker in open versus laparoscopic IHR has shown statistically significant reduction of POUR prevention in the laparoscopic group (95% CI 0.66 (0.47-0.92)), I2: 43%). The older age group benefited from pre-operative alpha-blocker use with reduced incidence of POUR post-IHR (95% CI 0.14 (0.08, 0.23), I2: 0%)). Gender did not affect the difference of incidence of POUR post-IHR despite pre-operative alpha-blockers (95% CI 0.62 (0.27, 1.44)), I2: 53%)). Overall, this meta-analysis has shown that administration of prophylactic alpha-blockers did not prevent POUR. However, there was statistically significant reduction of POUR in patients undergoing laparoscopic IHR as compared to open, as well as in older patients (age more than 60years) after administration of pre-operative alpha-blocker. Hence, the use of pre-operative alpha-blocker especially in older patients should be considered and more RCTs should be undertaken.

Spinal Anesthesia for Primary Hip and Knee Arthroplasty: Comparative Rates of Transient Neurological Symptoms and Urinary Retention Using Lidocaine, Mepivacaine, and Bupivacaine

BackgroundShort-acting spinal anesthetics enable rapid recovery after hip and knee arthroplasty; however, concerns with transient neurological symptoms (TNS) cause some to avoid using lidocaine. Postoperative urinary retention (POUR) is also a concern with spinal anesthesia. We sought to study the comparative rates of TNS and POUR between lidocaine, mepivacaine, and bupivacaine in a high-volume hip and knee arthroplasty setting. MethodsData for 1,217 primary THA, TKA, and unicompartmental knee arthroplasty cases were reviewed and grouped by spinal anesthetic agent (lidocaine, mepivacaine, or bupivacaine). Of the 1,217 cases, utilization was 523 lidocaine, 573 mepivacaine, and 121 bupivacaine. The incidence of TNS and POUR requiring catheterization was measured both by clinical evaluation as well as a questionnaire sent to patients 14 days postoperatively. ResultsThe overall rate of TNS was 8%. With the numbers available, there was no difference in rates of TNS between groups (6.9% lidocaine, 9.2% mepivacaine, and 4.1% bupivacaine; P = .297). There was no difference in rates of TNS or POUR between THA and TKA/unicompartmental knee arthroplasty. Bupivacaine had a significantly higher rate of urinary retention (9.1%; P < .001) than mepivacaine (2.8%) or lidocaine (1.5%). ConclusionThis study showed no difference in the rate of TNS between the 3 common agents used in spinal anesthesia. Short-acting spinal anesthetics such as lidocaine and mepivacaine can lower the rate of POUR requiring catheterization, helping to enable rapid recovery after hip and knee arthroplasty.

The implementation of enhanced recovery after surgery pathway in patients undergoing posterior thoracolumbar fusion for degenerative spinal deformity

PurposeThe prevalence of degenerative spinal deformity (DSD) and the increased cost of correction surgery impose substantial burdens on the health care and insurance system. The aim of our study was to investigate the effects of the implementation of Enhanced Recovery After Surgery (ERAS) protocol on postoperative outcomes after complex spinal surgery.MethodsA retrospective analysis of prospectively established database of DSD was performed. The consecutive patients who underwent open correction surgery for degenerative spinal deformity between August 2016 and February 2022 were reviewed. We extracted demographic data, preoperative radiographic parameters, and surgery-related variables. The ERAS patients were 1:1 propensity-score matched to a historical cohort by the same surgical team based on age, gender, BMI, and number of levels fused. We then compared the length of hospital stay (LOS), physiological functional recovery, and the rates of complications and readmissions within 90 days after surgery between the groups.ResultsThere were 108 patients included, 54 patients in the ERAS cohort, and 54 patients matched control patients in the historical cohort. The historical and ERAS cohorts were not significantly different regarding demographic characteristics, comorbidities, preoperative parameters, operative time, and reoperation rate (P > 0.05). Patients in the ERAS group had significantly shorter postoperative LOS (12.0 days vs. 15.1 days, P = 0.001), average days of drain and urinary catheters placement (3.5 days vs. 4.4 days and 1.9 days vs 4.8 days, respectively), and lower 90-day readmission rate (1.8% vs. 12.9%, P = 0.027). The first day of assisted-walking and bowel movement occurred on average 1.9 days (2.5 days vs. 4.4 days, P = 0.001) and 1.7 days (1.9 days vs. 3.6 days, P = 0.001) earlier respectively in the ERAS group. Moreover, the rate of postoperative urinary retention (3.7% vs. 16.7%, P = 0.026) and surgical site infection (0% vs. 7.4%, P = 0.046) were significantly lower with ERAS protocol applied.ConclusionsOur study confirmed that the ERAS protocol was safe and essential for patients undergoing thoracolumbar deformity surgery for DSD. The ERAS protocol was associated with a shorter postoperative LOS, a lower rate of 90-day readmission, less rehabilitation discharge, and less postoperative complications.

Prophylactic doxazosin reduces urinary retention and promotes recovery after total joint arthroplasty: A randomized controlled trial.

Background: Postoperative urinary retention (POUR) is a common and disruptive complication following total joint arthroplasty (TJA). The aim of this study is to investigate whether doxazosin can decrease the incidence of POUR and promote recovery under the setting of modern enhanced recovery after TJA. Methods: In this randomized placebo-controlled trial, patients over 35years of age undergoing primary unilateral TJA were recruited. Patients received doxazosin (4mg once) or placebo 2h before surgery. The primary outcome of interest was the development of POUR, which was diagnosed when patients with a urine volume over 400ml or overflow incontinence. Postoperative recovery was assessed in terms of hospital length of stay after surgery, daily ambulation distance, visual analogue scale (VAS) pain score and opioid consumption. Results: A total of 170 male patients were equally randomized into Doxazosin group (mean age 54.2 ± 13.7years, range 36-88years) and Placebo group (mean age 54.6 ± 13.9years, range 38-81years). The POUR rate was significant lower in Doxazosin group (17.6%) than in Placebo group (36.5%) (p = .006). The mean LOS in the Doxazosin group was 3.1 ± 1.1days compared to 3.6 ± 1.7days in the Placebo group (p = .030). Doxazosin group had a longer daily mobilization distance than Placebo group on postoperative day 1 (26.8 ± 11.1 vs. 22.8 ± 9.7; p = .015). Postoperative pain assessed by VAS score and opioid usage was comparable between two groups. Conclusion: Our results support the routine use of prophylactic doxazosin in male patients to decrease POUR rate and promote postoperative recovery under the setting of modern enhanced recovery after TJA.

Postoperative urinary retention following hip or knee arthroplasty under spinal anaesthesia with intrathecal morphine: a retrospective cohort study.

Postoperative urinary retention (POUR) frequently complicates the course of patients following hip and knee arthroplasty. Intrathecal morphine (ITM) was identified as a significant risk factor for POUR. The objective of this study was to investigate the incidence and risk factors for POUR in fast-track total joint arthroplasty (TJA) under spinal anaesthesia (SA) with ITM. We conducted a retrospective study of our institutional joint registry of patients who underwent primary TJA under SA with ITM between October 2017 and May 2021. Preoperative (baseline demographics) and perioperative data were collected. The primary outcome was the incidence of POUR after 8 h or earlier, either due to lack of voiding or according to patient's complaints of bladder distension. Univariate and adjusted analyses were performed to identify predictors of POUR. Sixty-nine patients who underwent total knee arthroplasty (TKA) and 36 patients who underwent total hip arthroplasty (THA) under SA with ITM were included in the study. POUR requiring bladder catheterisation was diagnosed in 21% of patients. Independent predictors of POUR were age over 65 years and male gender. SA with ITM for TJA is associated with high rates of POUR in males older than 65 years of age. Other previously identified risk factors such as intraoperative fluid administration or comorbidities may not be as influential.

Post-Operative Voiding Function after Total Laparoscopic Hysterectomy with Transvaginal Versus Transabdominal Morcellation

<h3>Study Objective</h3> To determine the rates of post-operative urinary retention (POUR) in patients who have undergone transvaginal and transabdominal morcellation for large multifibroid and adenomyotic uteri during a total laparoscopic hysterectomy. <h3>Design</h3> Retrospective, multi-centre, cohort study. <h3>Setting</h3> Multi-centre healthcare system serving Calgary and Southern Alberta population. <h3>Patients or Participants</h3> The patients of four high-volume minimally invasive gynecologists were included in this study. Women 18 years and older who underwent a total laparoscopic hysterectomy requiring morcellation between January 2015 to April 2021 were included. Those with pre-existing urinary retention were excluded. <h3>Interventions</h3> Retrospective observational cohort study. <h3>Measurements and Main Results</h3> POUR was defined as urinary retention requiring an indwelling or in-and-out catheter post-operatively prior to discharge. No difference in POUR was found between transvaginal (29/139, 20.9%) and transabdominal (12/56, 21.4%) morcellation. There were also no differences in time to first post-operative void (5.5±4.5h vs 5.75±3.25h), length of stay (23±5h vs 22±6h), post-operative UTI (5.1% vs 3.6%) or presentation to the emergency department for POUR post-discharge (1.4% vs 1.8%) for transvaginal and transabdominal morcellation, respectively. A trend towards increased complication rate at the time of morcellation (7% vs 0%) and urinary complaints at post-operative follow-up appointments (9.4% vs 0%) were noted in the vaginal morcellation group. <h3>Conclusion</h3> With respect to route of uterine morcellation, patients who undergo transvaginal and transabdominal approaches have similar rates of POUR. It is reasonable for surgeon preference to guide the decision about route of morcellation. Larger prospective trials are needed to further assess POUR and the potential increased complication rate and post-operative urinary complaints with transvaginal morcellation.

Does tamsulosin decrease postoperative urinary retention in spine surgery? A double-blind, randomized controlled trial.

The authors' objective was to determine whether preoperative administration of tamsulosin decreases postoperative urinary retention after spine surgery. In this randomized, double-blind, placebo-controlled clinical trial performed at a single institution between 2016 and 2019, eligible males aged 50 to 85 years were administered tamsulosin or placebo for 5 days prior to elective spine surgery. Patients were excluded if they were taking alpha adrenergic blocking drugs; were allergic to tamsulosin, lactose, or sulfa drugs; had a preexisting indwelling urinary catheter, orthostatic hypotension, history of urological surgery, or renal failure; or were scheduled for cataract surgery within 2 weeks. Screening identified 1051 eligible patients (140 declined participation, 150 did not meet the inclusion criteria, and 151 did not enroll for other reasons). A total of 610 patients were randomly assigned to receive 0.4 mg oral tamsulosin or an identical placebo capsule for 5 days preoperatively and 2 days postoperatively. A total of 497 patients were included in the final statistical analysis. The overall rate of postoperative urinary retention was 9.7%, and tamsulosin had no observed effect on reducing the rate of postoperative urinary retention as compared with placebo (9.4% vs 9.9%, p = 0.96). There were no significant differences in the reported adverse events between groups. Multivariate logistic regression was performed to model the effects of patient, surgical, and anesthetic factors on postoperative urinary retention, and the study drug remained an insignificant factor. This study did not detect an effect of perioperative tamsulosin on reducing the rate of postoperative urinary retention in male patients aged 50 to 85 years who underwent elective spine surgery. This study does not support the routine use of tamsulosin to reduce postoperative urinary retention in patients without a previous prescription. It is unknown if subpopulations exist for which prophylactic tamsulosin may reduce postoperative urinary retention.

Minimally Invasive Transforaminal versus Anterior Lumbar Interbody Fusion in Patients Undergoing Revision Fusion: Clinical Outcome Comparison

We aim to compare perioperative/postoperative clinical outcomes between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and anterior lumbar interbody fusion (ALIF) in patients presenting for revision surgery. A retrospective database was reviewed for procedures between November 2005 and December 2021. Revision MIS-TLIF/ALIFs were included, whereas primary fusions or diagnosis of infection/malignancy/trauma were excluded. Patients were grouped into MIS-TLIF/ALIF cohorts. Preoperatively/postoperatively collected patient-reported outcome measures (PROMs) included visual analog scale back/leg score, Oswestry Disability Index, Patient-Reported Outcome Measurement Information System-Physical Function (PROMIS-PF), and Short-Form 12-Item Survey Mental/Physical Composite Scores. A total of 164 patients were eligible, with 84 patients in the MIS-TLIF cohort. The presence of degenerative spondylolisthesis and central stenosis, narcotic consumption on postoperative day 0/1, and postoperative urinary retention rates was greater in the MIS-TLIF cohort (P ≤ 0.036, all). Preoperative PROMs between cohorts did not significantly differ. Significantly favorable postoperative PROM scores were shown in the MIS-TLIF cohort with PROMIS-PF at 12 weeks/6 months (P ≤ 0.033, all). Most patients in both cohorts achieved overall minimum clinically important difference for visual analog scale back/leg score, Oswestry Disability Index, Short-Form 12-Item Survey Physical Composite Score, and PROMIS-PF. No differences were noted between cohorts within rates of MCID achievement. Patients undergoing revision fusion via MIS-TLIF or ALIF reported similar 1-year postoperative mean outcomes and rates of meaningful clinical achievement for physical function, mental health, disability, and back/leg pain. However, patients undergoing revision MIS-TLIF reported improved physical function at 12 weeks and 6 months. Perioperatively, patients undergoing revision MIS-TLIF were noted to consume significantly greater quantities of narcotics.

Effect of Intraoperative Urinary Catheter Use on Postoperative Urinary Retention After Laparoscopic Inguinal Hernia Repair

Urinary catheters are commonly placed during laparoscopic inguinal hernia repair as a presumed protection against postoperative urinary retention (PUR), one of the most common complications following this operation. Data from randomized clinical trials evaluating the effect of catheters on PUR are lacking. To investigate the effect of intraoperative catheters on PUR after laparoscopic inguinal hernia repair. This 2-arm registry-based single-blinded randomized clinical trial was conducted at 6 academic and community hospitals in the US from March 2019 to March 2021 with a 30-day follow-up period following surgery. All patients who presented with inguinal hernias were assessed for eligibility, 534 in total. Inclusion criteria were adult patients undergoing laparoscopic, elective, unilateral, or bilateral inguinal hernia repair. Exclusion criteria were inability to tolerate general anesthesia and failure to understand and sign the written consent form. A total of 43 patients were excluded prior to intervention. Patients in the treatment arm had placement of a urinary catheter after induction of general anesthesia and removal at the end of procedure. Those in the control arm had no urinary catheter placement. PUR rate. Of the 491 patients enrolled, 241 were randomized to catheter placement, and 250 were randomized to no catheter placement. The median (IQR) age was 61 (51-68) years, and 465 participants (94.7%) were male. Overall, 44 patients (9.1%) developed PUR. There was no difference in the rate of PUR between the catheter and no-catheter groups (23 patients [9.6%] vs 21 patients [8.5%], respectively; P = .79). There were no intraoperative bladder injuries. In the catheter group, there was 1 incident of postoperative urethral trauma in a patient who presented to the emergency department with PUR leading to a suprapubic catheter placement. Intraoperative urinary catheters did not reduce the risk of PUR after laparoscopic inguinal hernia repair. While their use did not appear to be associated with a high rate of iatrogenic complications, there may be a low rate of catastrophic complications. In patients who voided urine preoperatively, catheter placement did not appear to confer any advantage and thus their use may be reconsidered. ClinicalTrials.gov Identifier: NCT03835351.

Are Formal Voiding Trials Necessary After Posterior Compartment Reconstructive Surgery?

Posterior compartment surgery is considered a risk factor for postoperative urinary retention because of the impact of postoperative pain on the pelvic floor; however, few studies have examined the association between posterior compartment reconstructive surgery and urinary retention. The aim of the study was to compare rates of urinary retention in patients undergoing vaginal reconstructive surgery, without hysterectomy, in the posterior compartment only versus any apical and/or anterior compartment (with or without posterior compartment). In this retrospective cohort study, we evaluated patients who underwent surgery, without hysterectomy, in the posterior compartment only versus any apical and/or anterior compartment (with or without posterior compartment) from January 2015 to November 2020. Our primary outcome was rate of postoperative urinary retention, defined as a failed voiding trial before discharge. Secondary outcome was days of catheterization. Multivariable logistic regression was performed to assess variables associated with a failed voiding trial. Of 362 patients, 141 (39.0%) underwent surgery in the posterior compartment only and 221 (61.0%) underwent vaginal apical and/or anterior compartment surgical procedures. Rate of retention was significantly lower in the posterior compartment only group (9.9% vs 41.6%, P < 0.001). The median numbers of days of catheterization were significantly fewer in the posterior compartment only group (0 [0,0] vs 0 [0,3], P < 0.001). In multivariable logistic regression, posterior compartment only surgery was associated with passing the voiding trial (odds ratio, 6.0; 95% confidence interval, 2.97-12.03). Rates of postoperative urinary retention after surgery in the posterior compartment are low, and these patients may not require formal voiding trials after surgery.

Routine Indwelling Urinary Catheterization Is Not Necessary During Total Hip Arthroplasty Performed Under Spinal Anesthesia

BackgroundPerioperative indwelling urinary catheterization remains common in patients undergoing total hip arthroplasty. This study sought to examine the effect of routine catheterization following total hip arthroplasty performed under spinal anesthesia on urinary complications.MethodsA total of 991 consecutive patients who underwent primary total hip arthroplasty under spinal anesthesia over a 4-year period were retrospectively reviewed. Major postoperative urinary retention (POUR) was defined as persistent retention following 2 straight catheterizations, which required postoperative indwelling catheter placement. Minor POUR was defined as retention that resolved following 1 or 2 straight catheterizations. Statistical analyses were used to compare outcomes between those who received a routine indwelling catheter and those who did not.ResultsOf the 991 patients included, 498 (50.3%) underwent routine indwelling urinary catheter placement preoperatively. Routine indwelling catheterization was associated with a higher rate of urinary tract infection (1.4% vs 0.0%, P = .015), but a lower rate of minor POUR (5.0% vs 10.3%, P = .001). There was no difference with respect to the rate of major POUR or discharge with an indwelling catheter. Multivariate analyses demonstrated indwelling catheterization to be independently associated with a lower rate of minor POUR (P = .021), but there was no association with overall POUR, major POUR, or discharge with a urinary catheter.ConclusionThese data suggest that routine indwelling urinary catheterization is likely unnecessary for patients undergoing total hip arthroplasty in the setting of spinal anesthetic and may even lead to increased risk of complications such as urinary tract infection.
