Cost Analysis of Bladder Catheterization After Pelvic Floor Surgery.

Approximately 15-45% of female patients develop transient postoperative urinary retention (POUR) following pelvic reconstructive surgery. Catheter options for bladder drainage include transurethral indwelling catheter (TIC), intermittent self-catheterization (ISC), and suprapubic tube (SPT). Each strategy has risks and benefits; none have been shown to be clinically superior, and to date, no comprehensive comparative economic analysis has been published. The objective of this study was to evaluate the cost of these different bladder catheterization strategies after transvaginal pelvic surgery. A Canadian universal single-payer (government funded) health system perspective was taken, and a decision tree model was constructed to evaluate the costs associated with each catheterization strategy over a 6-week horizon. Base-cases were set based on recently published clinical data of our institutions, 2 academic tertiary care centers, and based on systematic reviews and meta-analyses. Costs were established in consultation with process stakeholders, in addition to published values. The average cost calculated for management of transient POUR after outpatient pelvic reconstructive surgery was 150.69 CAD (median 154.86; interquartile range [IQR] 131.30-176.33) for TIC, 162.28 CAD (median 164.72; IQR 144.36-189.39) for ISC and 255.67 CAD (median 270.63; IQR 234.32-276.82) for SPT. In costing inpatient surgical data, the average cost calculated was 134.22 CAD (median 123.61; IQR 108.87-151.85) for TIC and 224.61 CAD (median 216.07; IQR 203.86-231.23) for SPT. TIC and ISC were found to be significantly less costly than SPT in managing transient POUR following transvaginal pelvic reconstructive surgery.

Understanding the challenges faced by men learning to live with clean intermittent self-catheterisation.

Clean intermittent self-catheterisation (CISC) is considered the preferred option to an indwelling catheter for emptying the bladder in people with a range of voiding dysfunctions. CISC has a lower risk of complications and urinary tract infections. This narrative review of previous qualitative research explores the quality-of-life impacts and highlights the challenges that men face. It will provide nurses who teach CISC with some useful insights into the male experience and the issues of concordance and adherence. This will help to better inform and guide clinical practice in this specialist area of nursing practice.

Product evaluation of the Luja Micro-hole Zone Technology in clean intermittent self-catheterisation

Clean intermittent self-catheterisation is a common procedure undertaken by people with bladder dysfunction. However, it is not without its complications, the main one being urinary tract infection. The most common causes of urinary tract infections are poor hygiene, technique and adherence, excessive post-void residual urine and bladder trauma. A catheter with new Micro-hole Zone Technology has been developed, which can potentially improve bladder emptying and minimise these complications. A case study is used to illustrate its effects in practice.

Factors associated with symptomatic urinary tract infection in persons with spinal cord lesions who perform clean intermittent catheterization with single-use catheters.

To investigate factors associated with symptomatic urinary tract infection (sUTI) in persons with chronic spinal cord lesion (SCL) who were using single-use catheters for intermittent self-catheterization (ISC). Among respondents to an internet survey on the burden of illness on persons with SCL who were considered to be able to perform ISC, 111 persons using single-use catheters were included to examine factors associated with self-reported sUTI by univariate as well as multivariable analysis. The incidence of sUTI was significantly higher in males than in females (56.9% vs. 31.6%, p = .011), persons with stocks of antibiotics than those without it (82.9% vs. 28.6%, p < .011), and persons with more frequent bleeding during catheterization than those with less frequent bleeding (100% vs. 46.5%, p = .036). The incidence did not significantly differ between respective groups when various variables were evaluated by other characteristics of the participants, adherence to ISC procedures, and complications. On multivariable analysis, male gender and stocks of antibiotics were significant independent factors for sUTI. Male gender and stocks of antibiotics were associated with sUTI in persons with SCL who were performing ISC with single-use catheters.

Intermittent catheterisation.

When an individual has voiding difficulties, the person may require a urinary catheter. Enabling the person to choose an appropriate method of catheterisation and supporting them can have an enormous impact on the individual's health and wellbeing. Indwelling urethral catheters are suitable for some people but for others they can affect a person's lifestyle and lead to depression. Intermittent catheterisation can work well for some people. Intermittent self-catheterisation has been used to manage urinary retention for over 3500 years. It remains the 'gold standard' in terms of bladder drainage, but it is under-used and indwelling catheters remain more common. This article examines the history of intermittent catheterisation, indications for self-catheterisation and how to support people to use self-catheterisation.

Isolated continent cystostomy on neurologic native bladder: Functional results

IntroductionContinent cutaneous urinary diversion (CCUD) is proposed to patients suffering from chronic neurologic retention and undergoing intermittent self-catheterization (ISC). In case of neurogenic detrusor overactivity (NDO), augmentation enterocystoplasty is often required. The aim was to identify the prevalence of urinary stomal and/or urethral leakage in patients who had not undergone enlargement. MethodsMonocentric, retrospective study of patients who underwent CCUD surgery in a neuro-urological context. Mitrofanoff's, Monti's or Casale's channels were performed. Patients selected had an underactive, stable, or stabilized bladder under adjuvant therapy with proper cystomanometric capacity. Prior or concomitant enterocystoplasty were excluded. Failure was defined as the occurrence of clinical leakage whatever it is through urinary stomal, or urethral. Urodynamic parameters were also reported. ResultsThirty-one patients underwent surgery. Nine women had a concomitant bladder neck sling and 1 urethral closure. The mean follow-up was 7 years. 8/31 (26%) had stomal leakage and 9 urethral leakage (29%). Five spinal cord injured patients (n=14) had stomal leakage (36%) and 6 urethral leakage (43%). Of the 25 postoperative urodynamic parameters, cystomanometric bladder capacity was 419mL (vs. 514mL) and 2 additional patients had de novo NDO (9 vs. 7). DiscussionThe morbidity of augmentation enterocystoplasty is weighed against the presence of a well-controlled bladder preoperatively. Our study shows the appearance of leakage in some patients despite a well-balanced bladder, a decrease in mean cystomanometric capacity and an increase in the rate of NDO postoperatively. Good selection criteria for an isolated CCUD should be carefully revised and defined. Level of evidenceGrade C - retrospective study.

[Neurogenic, non-obstructive urinary retention: diagnosis and treatment].

Neurogenic, non-obstructive urinary retention has a varied aetiology. The condition can be caused by central-nervous diseases as well as by disorders of the peripheral nervous system. The formation of residual urine may lead to considerable problems that can have a significant impact on a patient's everyday life. A treatment appropriate for the lower urinary tract dysfunction and suited to the patient's situation in life is only possible if a differentiated diagnostic evaluation has been performed. Both conservative and surgical therapeutic strategies are available, while drug treatment approaches are less relevant. Neuromodulative procedures are particularly suitable for causal treatment of the dysfunction. For patients requiring artificial bladder voiding, intermittent self-catheterization is generally preferable to using an indwelling catheter.

Imaging and video of late preterm delivery by midline laparotomy due to incarcerated uterus: A case report and literature review of a rare but morbid condition.

Incarcerated gravid uterus (IGU) is a rare and serious obstetric complication. IGU is defined as the entrapment of the gravid uterus between the pubic symphysis and the sacral promontory. The incidence of IGU is 1 in 3000-10 000 cases. IGU is associated with significant obstetric complications, including preterm labor, intrauterine fetal death, growth restriction, renal failure, uterine ischemia/rupture and thrombosis. Here, we present the case of a primigravida with urinary retention at 14 weeks. On transabdominal ultrasound at 19+5/7 weeks the cervix was difficult to visualize, and the anterior uterine wall appeared thickened. The bladder was elongated superior to the uterus and the placenta was low-lying. Initially the patient was managed with intermittent self-catheterization, and subsequently indwelling catheterization was required from 22 weeks. At 30 weeks, the patient was transferred to a tertiary center and magnetic resonance imaging (MRI) was preformed due to challenging visualization of the cervix on ultrasound and the patient's continued symptoms of constipation and recurrent urinary infections. The MRI found a retroflexed gravid uterus, with vagina and endocervix displaced anteriorly and compressed by the gravid uterus. The findings were consistent with an incarcerated uterus. The patient subsequently had positive urinary cultures for Pseudomonas and rising creatinine. Given the obstructive uropathy and associated morbidity and mortality, a plan for elective pre-term delivery at 33+6/7 weeks was made. Delivery was by midline laparotomy, normal anatomy was restored after manual evacuation of the fundus from below the sacral promontory, and an uncomplicated lower segment transverse uterine cesarean section was performed.

Purulent pericarditis caused by methicillin-sensitive Staphylococcus aureus bacteriuria

BackgroundPurulent pericarditis (PP)— a purulent infection involving the pericardial space—requires a high index of suspicion for diagnosis as it often lacks characteristic signs of pericarditis and carries a mortality rate as high as 40% even with treatment. Common risk factors include immunosuppression, diabetes mellitus, thoracic surgery, malignancy, and uremia. Most reported cases of PP occur in individuals with predisposing risk factors, such as immunosuppression, and result from more commonly observed preceding infections, such as pneumonia, osteomyelitis, and meningitis. We report a case of PP due to asymptomatic bacteriuria in a previously immunocompetent individual on a short course of high-dose steroids.Case presentationAn 81-year-old male presented for severe epigastric pain that worsened with inspiration. He had been on high-dose prednisone for presumed inflammatory hip pain. History was notable for urinary retention requiring intermittent self-catheterization and asymptomatic bacteriuria and urinary tract infections due to methicillin-sensitive Staphylococcus aureus (MSSA). During the index admission he was found to have a moderate pericardial effusion. Pericardial fluid cultures grew MSSA that had an identical antibiogram to that of the urine cultures. A diagnosis of purulent pericarditis was made.ConclusionPP requires a high index of suspicion, especially in hosts with atypical risk factors. This is the second case of PP occurring as a result of asymptomatic MSSA bacteriuria. Through reporting this case we hope to highlight the importance of early recognition of PP and the clinical implications of asymptomatic MSSA bacteriuria in the setting of urinary instrumentation and steroid use.

Intermittent Self-catheterization for Bladder Dysfunction After Deep Endometriosis Surgery: Duration and Factors that Might Affect the Recovery Process

ObjectiveTo assess the duration needed for regaining normal bladder voiding function in patients with postoperative bladder dysfunction requiring intermittent self-catheterization after deep endometriosis surgery, and identify risk factors that might affect the recovery process. DesignRetrospective study based on data recorded in a large prospective database. SettingEndometriosis referral center. PatientsFrom September 2018 to June 2022, 1,900 patients underwent excision of deep endometriosis in our center. 61 patients were discharged with recommendation for intermittent self-catheterization and were thus included in the study. InterventionsIntermittent self-catheterization after endometriosis surgery. Measurements and Main Results43 patients (70.5%) stopped self-catheterization during the follow up period. Median follow up was 25 weeks (range, 7 to 223 weeks). Surgery was performed laparoscopically in 48 patients (78.7%) and robotically in 13 (21.3%). 47 patients (77%) had nodules involving the digestive tract, 11 (18%) had urinary tract involvement, 29 had parametrial nodules (47.5%) and 13 (21.3%) had sacral plexus involvement. The probability of bladder voiding function recovery and arrest of self-catheterization was 24.5%, 54%, 59%, 72%, and 77% at 4, 8, 12, 52, and 78 weeks respectively. Cox's multivariate model identified preoperative bladder dysfunction as the only statistically significant independent predictor for arrest of self-catheterization (HR 0.36, 95%CI 0.15-0.83). ConclusionsPatients requiring intermittent self-catheterization for bladder dysfunction after deep endometriosis excision may spontaneously recover bladder function in 77% of cases. Symptoms suggesting preoperative bladder voiding dysfunction should be reviewed before planning surgery, and patients should be informed of the higher postoperative risk of long-term bladder voiding dysfunction.

Laparoscopic Modified Radical Hysterectomy for Severe Endometriosis: A Single-Center Case Series

Study objectiveThe main objective is to describe the feasibility and report a single centre experience of a standardized laparoscopic modified radical hysterectomy technique among patients with severe endometriosis and pouch of Douglas obliteration. DesignA single-center case series of laparoscopic modified radical hysterectomy performed at the Poissy Hospital between December 2012 and May 2021. SettingsSingle-center, gynecology unit (level III) with a focus on endometriosis. PatientsPatients with severe endometriosis (stage 4 AFS) and pouch of Douglas Obliteration. Measurements and Main ResultsFifty-two patients with severe endometriosis underwent the surgical procedure.Out of these patients: 23.1% underwent a rectal shaving (n= 12), 1.9 % a discoid resection (n= 1) and 17.3% a rectal resection (n= 9), including a protective ileostomy in one case. Ureterolysis was performed on 82.7% of patients (n= 43). The average hospital stay was 3.3 days (1-12). Seven patients required intermittent self-catheterization (13.5%). Minor complications (Clavien-Dindo grade 1 and 2) occurred to 25.9% of the patients and severe complications to 3.8% of them (Clavien-Dindo grade 3, no grade 4). Two patients (3.8%) were reoperated: one for a postoperative occipital alopecia (balding) and the other for vaginal dehiscence with evisceration. About 50 patients (96.2%) had a complete resection of endometriosis. The median follow-up was 14 months (interquartile range 6-23 months) with 94.3% of them improved (much and very much) and 3.8% minimally improved. ConclusionIn our experience, laparoscopic modified radical hysterectomy is a reliable procedure with a low rate of severe complications. This technique needs to be assessed by other surgeons and others centers across the country and abroad, in order to determine the likehood of it succeeding.

Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines). Preoperative patients’ informationEach patient must be informed concerning the risks associated with POP surgery (EO). Hemorrhage, hematomaVaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO). Bladder injuryWhen a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO). Ureter injuryAfter ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO). Rectal injuryRegardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO). Vaginal wall injuryAfter vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO). Mesh infection (abscess, cellulitis, spondylodiscitis)Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO).When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO).When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient. Bowel occlusion related to non-closure of the peritoneumPeritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO). Urinary retentionPreoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO). Postoperative painBefore POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO).Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C).When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO).When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO).When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO).Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO).Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO). Postoperative dyspareuniaWhen de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO). Vaginal mesh exposureTo reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C).When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material.When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered.When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO).When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh.Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO).When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO). Suture thread vaginal exposureFor women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed. Bladder and ureteral mesh exposureWhen bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B).Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

Antibiogram data of urinary tract infection in spinal cord injury patients in an outpatient setting.

To establish antibiogram data for patients with spinal cord injury (SCI) that would help differentiate the organisms commonly present depending on the voiding method and antibiotic sensitivity for empirical treatment. A total of 499 urine culture results were obtained from 151 SCI patients with symptomatic urinary tract infection (UTI) with significant bacteriuria and pyuria with more than 10 white blood cells per high power field. The voiding method was categorized as follows: self-intermittent catheterization (SIC), suprapubic catheter (SPC), Foley catheter, condom catheter, or voiding freely. The demographic data were as follows: male, n=124 (82.2%); female, n=27 (17.8%); mean age, 39; paraplegic n=105 (69.5%); and tetraplegic, n=45 (29.8%). The SIC was the most common voiding method (n=64, 42.3%), followed by Foley catheter (n=39, 25.8%). Escherichia coli was the most common organism overall (29%) and more frequent in patients using SIC as the voiding method. Proteus mirabilis was present more frequently in patients using SPC (33%), and Klebsiella pneumoniae in voiding freely cultures (30%). Antibiotic sensitivity was as follows Gentamicin (44.1%), Nitrofurantoin (39.1%), Augmentin (33.5%), and Ciprofloxacin (31.5%). Increased preference of the local population to foley catheter as a voiding method which needs to be investigated more. The type of voiding methods in patients with SCI results in different common causative organisms of UTI. Ciprofloxacin resistance profile increased overall except in patients voiding with SPC. Nitrofurantoin is the most overall sensitive oral antibiotic in our sample followed by Augmentin then Cefuroxime.

Long term safety outcomes and continuation rates of repeated Intravesical Botulinum Toxin A injections for Detrusor Overactivity: 16 year’s experience of a Tertiary Centre in the UK

Introduction:Overactive bladder (OAB) affects 27% of women in the UK with an adverse impact on quality of life. Medical treatment with anticholinergics has a high discontinuation rate due to side effects. OnabotulinumtoxinA (BOTOX ®) is an established treatment for refractory OAB, although there are little published data regarding safety with long term use. Objective:To report the long-term safety and continuation rates of intravesical Botox for OAB. Methods:This was a retrospective cohort study of patients treated with botulinum toxin A for OAB in a tertiary centre from 2007–2023. Data were collected retrospectively from medical records. Results:132 patients were identified, with a total of 574 episodes of intravesical Botox. Mean age at first treatment was 55 years. After 1st Botox treatment, 21% of patients developed urinary tract infections. Clean intermittent self-catheterisation (CISC) was performed in 33% of patients, 5% of whom were performing CISC prior to treatment. The range of number of Botox treatments per patient was 1–18; 74% had more than one treatment. 52% of patients were lost to follow-up and 30% are ongoing patients. Recurrent UTIs developed in 23%. Conclusion:Repeated Botox injections appear to be a safe form of treatment for refractory OAB. Long term complications include recurrent UTIs, which affects 1 in 4 women, and voiding dysfunction, which affects 1 in 5. Only 1 in 3 women continue long term Botox treatment.

A narrative review on the use of near-infrared spectroscopy to monitor bladder volume and in vitro validation approaches.

Current guidelines for patients with neurogenic bladder (NB) dysfunction suggest the use of self-intermittent catheterization with adherence to catheterization timers. Due to biorhythmic variability, unpredictable voiding times may occur. As a result, many patients abstain from extended social or work activities, turn to more secluded lifestyles, and generally experience a decrease in quality of life. Being able to know when to void is essential for patients with NB dysfunction. To solve the problem of variable void timings, wearable devices using near-infrared spectroscopy (NIRS) have been emergent and showed potential for bladder volume monitoring. Therefore, in this review, we provided a comprehensive overview of research which implemented NIRS for bladder volume monitoring, and discussed how the researchers validated their device by in-vitro methods and suggested a potential validation approach. A literature search using PubMed and Google Scholar was conducted on February 2023. Publications involving bladder volume monitoring incorporating NIRS technique with in-vitro validation was considered for review. Due to the novelty of NIRS being applied to bladder monitoring, there are a few possibilities to effectively validate this technique through in-vitro methods. Ballistics gel, which has been proven to be a versatile material for applications involving ultrasound, could be a suitable material when constructing a bladder phantom for in-vitro validation of NIRS technology. By outlining a more standardized in-vitro validation model based on ballistics gel, we hope to facilitate development in this field towards a more accurate and robust NIRS-based bladder monitoring device.

Evaluation of the efficacy of sacral neuromodulation in the treatment of voiding dysfunction after endometriosis surgery

Pelvic surgery for endometriosis is associated with a risk of bladder and digestive sequelae. Sacral neuromodulation (SNM) has been shown to be effective in the treatment of overactive bladder (OAB) and voiding dysfunction (VD). This study aimed to evaluate the efficacy of sacral neuromodulation (SNM) in treating voiding dysfunction (VD) following endometriosis surgery. A retrospective analysis was conducted on data from women who underwent SNM testing for persistent VD after endometriosis surgery. The study included 21patients from a French tertiary referral center. Patient characteristics, lower urinary tract symptoms, urodynamic findings, SNM procedures, and outcomes were assessed. The primary outcome was the success of SNM treatment for VD. After a median follow-up of 55months, 60% of patients achieved successful outcomes, with significant improvements of VD and quality of life. Moreover, more than half of patients who required clean intermittent self-catheterization (CISC) before SNM were able to wean off CISC. Complications such as infections and paraesthesia were observed, but overall, SNM was found to be effective and well tolerated. Age and the interval between endometriosis surgery and SNM testing were associated with treatment success. This study adds to the limited existing literature on SNM for VD after endometriosis surgery and suggests that SNM can be a valuable therapeutic option for these patients. Further research is needed to identify predictive factors and mechanisms underlying the effectiveness of SNM in this context. MRI-compatible and rechargeable devices, has improved the feasibility of SNM for these patients. In conclusion, SNM offers promise as a treatment option for persistent VD after endometriosis surgery, warranting further investigation. LEVEL OF EVIDENCE: 4.

Intermittent self-catheterisation: the gold standard for individuals with bladder dysfunction.

Intermittent self-catheterisation (ISC) has long been identified as the 'gold standard' for drainage of the bladder for individuals with bladder dysfunction. This article will outline identification of appropriate individuals, the types of intermittent self-catheters available, outline how it can improve quality of life for sufferers of bladder dysfunction, outline the complications that may occur and finally, suggest why it should be recommended as the 'gold standard' if it is taught and done correctly.

Temiz Aralıklı Kateterizasyon Uygulanan Hastaların Yaşam Kalitelerinin Kendileri Ve Bakım Verenleri Tarafından Değerlendirilmesi

Objective: The clean intermittent catheterization is a device used by individuals with neurogenic bladder. The ISC can be used by the patient or by a caregiver. The aim of this study is to examine the relationship between ISC practice skills and quality of life of individuals using ISC. Material and Methods: Between June 2018 and May 2019,126 patients using Clean Intermittent Self Catheterization (ISC) in a city hospital urology clinic was included in the study. All patients completed the Turkish version of the ISC-Q(T-ISC-Q) and Qualiveen questionnaires. ISC users were divided into two groups: Self-administered and caregiver practitioners. Spearman’s correlation coefficients between ISC-Q and Qualiveen were used. Results: The mean age of the patients was 51.53±16.47 years, and the duration of ISC was 42.15 ± 12.56 months. A total of 72 patients reported that they performed the ISC, while the number of patients who underwent ISC by the caregiver was 54. ISC-Q scores were 70.98±15.41 for ease of use, 42.85±18.40 for convenience, 75.71±14.97 for privacy, and 56.34±14.57 for psychological well-being, respectively. The results of the Cronbach α was 0.782. ISC-Q total score was positively correlated with Qualiveen total score (r=0.567, p=0.04). Patients who used their own ISC had higher ISC-Q scores than patients who had ISC administered by the caregiver. Conclusion: As a result, while the ease of use of ISC is high, there is a decrease in the convenience and psychological well-being of the patients using ISC. This was lower in patients who had ISC administered by the caregiver.

Transurethral laser lithotripsy using the Mitrofanoff urethral conduit for bladder stones: a case report

BackgroundThe Mitrofanoff (appendicovesicostomy) procedure is a contraindicated urinary modification that maintains urinary continence by forming a flap-valve mechanism at the site of anastomosis between the appendage and bladder wall, which is used as a guide for urinary drainage. This technique has been used by intermittent self-catheterization patients who have difficulty voiding from the native urethra or in cases where voiding from the abdominal wall would improve quality of life. However, the risk of stone formation is high due to intermittent urinary catheterization using the Mitrofanoff conduit urethrostomy as a conduit.Case presentationThe patient was a 22-year-old Asian-Japanese woman. At 6 years of age, she underwent bilateral vesicoureteral reflux surgery, Mitrofanoff urethrostomy using the appendix, abdominal wall plication, and vaginoplasty using the ileum. During follow-up, ultrasound performed due to persistent pain during urinary drainage revealed a 26 mm bladder stone. We performed ureteroscopic lithotripsy 6Fr using ureteral access sheath and made lithotripsy using Ho: YAG laser, then successfully removed the target stone.ConclusionsWe report a case of transurethral laser lithotripsy using the Mitrofanoff urethral conduit for bladder stones. Using with ureteral access sheath made lithotripsy and retrieved ureteral stone more effective.

Compliance of patients to clean intermittent self-catheterization after spinal cord injury

Clean intermittent self-catheterisation (CISC) was for many years considered the most preferable method to drain the bladder in patients with lower urinary tract disfunction. However, concerning long-term CISC, the adherence rate to the method was limited due to complications, psychological barriers, physical disabilities and social disadaptation. According to results of last studies hydrophilic catheters decrease the prevalence of recurrent urinary tract infections (UTIs) and urethral trauma. Thereby patients with voiding difficulties after spinal cord injury (SCI) could gain a better quality of life and acceptance of CISC. New coated catheters improved self-catheterisation techniques, personalised management, and better access to help and advice reduced the frequency of side effects. Furthermore, the percentage of unsatisfied patients who rejected the method fell. Consequently, CICS remains the most useable clean technique to drain the bladder regarding neuro-urological patients. Most of physicians have already admitted, that CICS seems to be a safe and easy-to-learn method. In this review we aimed to analyze all pros and cons of CICS relating to patients with lower urinary tract dysfunction after SCI.
