Intravesical injections of botulinum neurotoxin A to treat overactive bladder and/or detrusor overactivity related to multiple sclerosis: 5-Year continuation rate and specific risk factors for discontinuation-A study from the neuro-urology committee of the French Association of Urology.

BACKGROUND: While intravesical injections of botulinum neurotoxin A (BoNT-A) are currently recommended for patients experiencing refractory neurogenic overactive bladder and/or detrusor overactivity (OAB/DO), it is unclear how much this therapy is effective and sustainable in the long-term in patients with multiple sclerosis (MS). OBJECTIVES: To assess the mid-term continuation rate of BoNT-A injections to treat neurogenic OAB/DO in MS patients and to investigate MS-specific risk factors for discontinuation. METHODS: This retrospective study involved 11 French university hospital centers. All MS patients who received BoNT-A to treat neurogenic OAB/DO between 2008 and 2013 and were subsequently followed up for at least 5 years were eligible. RESULTS: Of the 196 MS patients included, 159 (81.1%) were still under BoNT-A 5 years after the first injection. The combination of the Expanded Disability Status Scale (EDSS < 6 or ⩾ 6) and of the MS type (relapsing-remitting vs progressive) predicted the risk of discontinuation. This risk was 5.5% for patients with no risk factor, whereas patients presenting with one or two risk factors were 3.3 and 5.7 times more likely to discontinue, respectively. CONCLUSION: BoNT-A is a satisfying mid-term neurogenic OAB/DO therapy for most MS patients. Combining EDSS and MS type could help predict BoNT-A discontinuation.

Which revision strategy is the best for non-mechanical failure of male artificial urinary sphincter?

PURPOSE: Persistence or recurrence of stress urinary incontinence (prSUI) after artificial urinary sphincter (AUS) implantation may be secondary to non-mechanical failure (NOMECA). It have for long been assumed to result from urethral atrophy. Its existence is now debated. As the pathophysiology of NOMECA is not elucidated, the most appropriate management remains unclear. We aimed to compare the several revision techniques for NOMECA of AUS in men. METHODS: NOMECA was defined as prSUI, with normally functioning device, no erosion, infection or fluid loss. Exclusion criteria were neurogenic SUI, revision or explantation for other causes. From 1991 to 2022, 143 AUS revisions for NOMECA, including 99 cuff DOWNSIZING, 10 cuff repositioning (RELOC), 13 TANDEM-CUFF placement, 18 cuff changing (CHANGE), three increasing balloon pressure (BALLOON-UP), were performed in 10 centers. BALLOON-UP patients weren't included in comparative analysis due to small sample size. All components could be changed during the revision. Patients were also categorized in COMPLETE-CHANGE vs. PARTIAL-CHANGE of the device. RESULTS: The three-months complete continence rate was 70.8% with a significant difference between RELOC and DOWNSIZING groups (p = 0.04). COMPLETE CHANGE was significantly associated with complete continence status at three months in multivariate analysis (83.3% vs. 63.3%, OR = 2.7; CI 95% [1.1-7.1], p = 0.03). Estimated five-year reoperation-free and explantation-free survival were respectively 63.4% and 75.9% (p = 0.16; p = 0.30). Those were significantly longer in COMPLETE-CHANGE vs PARTIAL-CHANGE (82.2% vs. 69.6%, p = 0.03); (71.2% vs. 58.2%, p = 0.047). CONCLUSIONS: AUS revision for prSUI due to NOMECA yields satisfactory outcomes regardless of the technique used. We observed better functional outcomes when repositioning the new cuff. COMPLETE-CHANGE may improve functional outcomes, explantation-free and reoperation-free survivals.

Sleep Disorders, Comorbidities, Actions, Lower Urinary Tract Dysfunction, and Medications ("Sleep C.A.L.M.") in the evaluation and management of nocturia: A simple approach to a complex diagnosis.

INTRODUCTION: Nocturia arises from a fundamental mismatch between nocturnal urine production, storage capacity, and sleep architecture, which may be driven by abnormalities of the genitourinary tract, but also by sleep disorders, medical diseases, patient actions/lifestyle factors, or medications. This article introduces a novel system for organizing the complex differential diagnosis for nocturia, as proposed by an international collective of practicing urologists, physician specialists, and sleep experts: "Sleep CALM"-Sleep Disorders, Comorbidities, Actions, Lower Urinary Tract Dysfunction, and Medications. METHODS: Narrative review of current evidence regarding the relevance of each "Sleep CALM" factor to nocturia pathogenesis, evaluation, and management. RESULTS: Nocturia and sleep disorders are highly intertwined and often bidirectional, such that nocturnal awakenings for reasons other than a sensation of bladder fullness should not be used as grounds for exclusion from nocturia treatment, but rather leveraged to broaden therapeutic options for nocturia. Nocturia is an important potential harbinger of several serious medical conditions beyond the genitourinary tract. Urologists should have a low threshold for primary care and medical specialty referral for medical optimization, which carries the potential to significantly improve nocturnal voiding frequency in addition to overall health status. Adverse patient actions/lifestyle factors, lower urinary tract dysfunction, and medication use commonly coexist with disordered sleep and comorbid medical conditions, and may be the primary mediators of nocturia severity and treatment response, or further exacerbate nocturia severity and complicate treatment. CONCLUSION: "Sleep CALM" provides a memorable and clinically relevant means by which to structure the initial patient history, physical exam, and clinical testing in accordance with current best-practice guidelines for nocturia. Although not intended as an all-encompassing diagnostic tool, the "Sleep CALM" schema may also be useful in guiding individualized ancillary testing, identifying the need for specialty referral and multidisciplinary care, and uncovering first-line treatment targets.

How I Do It: Transcutaneous tibial nerve stimulation TENSI+ system.

Overactive bladder (OAB) is a common condition that significantly impacts the quality of life (QoL), well-being and daily functioning for both men and women. Among various treatments, peripheral tibial nerve stimulation (PTNS) emerges as an effective third-line treatment for OAB symptoms, with options for either a percutaneous approach (P-PTNS) or by transcutaneous delivery (T-PTNS). Recent studies have shown negligible differences between P-PTNS and T-PTNS efficacy in alleviating urinary urgency and frequency and QoL improvement and, overall no difference in efficacy over antimuscarinic regimens. The TENSI+ system offers a cutting-edge transcutaneous approach, allowing patients to self-administer treatment conveniently at home with electrical stimulation delivery through surface electrodes. It stands out for its ease of preparation, tolerability, and high levels of patient satisfaction. Prospective multicentric data highlights TENSI+ to be an effective and safe treatment for lower urinary tract symptoms with high treatment adherence at 3 months. This paper aims to familiarize readers with the TENSI+ system, current studies, device assembly, operation, and treatment recommendations.

Efficacy and safety of the TENSI+ device for posterior tibial nerve stimulation: A multicenter, retrospective study.

OBJECTIVES: Transcutaneous posterior tibial nerve stimulation (TC-PTNS) is a validated option for lower urinary tract symptoms (LUTS) management, with a short-term success rate of around 60% and few adverse events. Our goal was to report the efficacy and safety results of TC-PTNS using the newly issued device TENSI+ for LUTS management. PATIENTS AND METHODS: A multicenter, retrospective study was conducted in 7 urology departments in France. All patients treated with TC-PTNS for LUTS using the TENSI+ device between September 2021 and February 2022 were included. All patients received supervised at-home training by a specialized nurse. All patients were asked to do daily, 20minutes sessions of TC-PTNS. Patient demographics, history, initial symptoms and previous treatment were collected at inclusion. A follow-up visit was scheduled at 3 months. Efficacy was evaluated through treatment persistence at 3 months and PGI-I (Patient Global Impression of Improvement) score. Adverse events were recorded. RESULTS: One hundred and three patients (86 women and 17 men) were included. All patients had overactive bladder symptoms, 64 suffered from urgency incontinence, and 24 had associated voiding symptoms. Eighteen patients had neurogenic background, and 30 previously received anticholinergics. After a median follow-up of 12 [10-21]weeks, 70 patients were still using the device (68%). PGI-I score reflected an improvement in 70.9% and was 1, 2 and 3 in 28, 26 and 19 patients respectively, while 24 were unchanged and 6 were worse. No clinical baseline parameter was predictive of success. Adverse events included pain at stimulation site (two cases) and pelvic pain (two patients), which rapidly resolved after treatment interruption. CONCLUSIONS: TC-PTNS with TENSI+ device is an effective option for LUTS management, with results that seem similar to other TC-PTNS approaches. Adverse events were mild and reversible after treatment interruption.

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 21 patients 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 55 months, 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.

[Multidisciplinary meetings in pelvic floor disease in women: A national survey by the CUROPF among French urologists]. / Réunion de concertation pluridisciplinaire en pelvipérinéologie en France : résultats d'une enquête nationale du CUROPF auprès des urologues français.

INTRODUCTION: Multidisciplinary team meetings (MTMs) in the field of pelvic floor diseases in women tend to generalize, as they are required as mandatory before mid-urethral sling implantation or sacrocolpopexy by recent decrees published by the French health authorities. However, access to these meetings is variable in the French territory. The goal of the present study was to describe the existence and the settings of these kinds of meetings in France. MATERIEL AND METHODS: An on-line survey was conducted between June and July 2020 (stage 1) then between November 2021 and January 2022 (stage 2). A 15-item questionnaire was sent to all members of the Association française d'urologie (AFU). A descriptive analysis was conducted. RESULTS: Three hundred and twenty-two completed questionnaires were sent back during stage 1 and 158 during stage 2. Early 2022, 61.3% of respondents had access to a pelviperineology MTM, with important difference according to geographical areas. Main activity of MTMs was case discussion of complex situations (68% of meetings). At the end of 2021, 22% of the respondents declared willing to stop partially or totally their pelviperineology activity, given the new regulations set in place by the authorities. CONCLUSION: Despite being absolutely mandatory in current clinical practice, MTMs in pelvic floor disease have spread slowly. MTMs implementation was still insufficient in 2022, and variable on the French territory. Some urologists declare having no access to such resources and about 1 out of 5 were considering to voluntary stop of decrease significantly their activity in this difficult context.

Impact of COVID-19 pandemic on functional urology procedures in France: a prospective study.

PURPOSE: To evaluate the impact of COVID-19 pandemic on functional urology procedures in France. METHODS: A prospective study was conducted within 11 secondary and tertiary referral centers in France. Patients aged > 18 years who were diagnosed with a functional urology disease before the national lockdown (March 17th, 2020) and who required a surgery were included. Study period went from March 17th to September 30th 2020. The included interventions were listed according to the guidelines for functional urology enacted by the French Association of Urology and delay of reoperation was compared to the guidelines' delay. The primary outcome was the number of procedures left unscheduled at the end of the study period. Descriptive statistics were performed. RESULTS: From March 17th 2020 to September 3 rd 2020, 1246 patients with a previous diagnosis of a functional urological disease requiring a surgery were included. The mean follow-up was 140.4 days (± 53.4). Overall, 316 interventions (25.4%) were maintained whereas 74 (5.9%) were canceled, 848 (68.1%) postponed and 8 patients (0.6%) died. At the end of the follow-up, 184 patients (21.7%) were still not rescheduled. If the intervention was postponed, the mean delay between the initial and final date was 85.7 days (± 64.4). CONCLUSION: Overall, more than two thirds of interventions had to be postponed and the mean delay between the initial and final date was about three months.

Best nonsurgical managements of acute urinary retention: what's new?

PURPOSE OF REVIEW: To provide a comprehensive review of the nonsurgical management of acute urinary retention (AUR). RECENT FINDINGS: A recent meta-analysis confirmed that α-blockers are associated with higher rates of successful trial without catheter (TWOC) compared with placebo, while combination therapies do not significantly reduce the rate of recatheterization. Compared with standard TWOC, bladder perfusion with physiological serum prior to catheter removal is a simple and cost-effective method to increase TWOC success rates (odds ratio 2.41, 95% confidence interval 1.53-3.8), and to reduce time-to-discharge (-89.68 min, 95% confidence interval -160.55, -18.88). Clean intermittent catheterization (CIC) is increasingly used for urinary retention in patients with benign prostatic hyperplasia as existing data suggest that it may decrease the risk of urinary tract infections, accelerate spontaneous voiding recovery and might be more cost-effective compared with indwelling urethral catheterization. Ongoing trials are examining whether office-placed prostate stent may be a promising solution in patients with AUR. SUMMARY: The recent development of alternative approaches to traditional TWOC may lead to new therapies for treating patients with AUR. Further studies are needed as the level of evidence from published studies remains low.

Impact of radiation therapy on artificial urinary sphincter implantation in male patients: A multicenter study.

AIMS: To evaluate the impact of an history of radiation therapy on the outcomes of artificial urinary sphincter (AUS) implantation in male patients. METHODS: The charts of all patients who underwent AUS implantation for stress urinary incontinence (SUI) after prostate surgery in thirteen centers between 2004 and 2020 were retrospectively reviewed. We excluded patients with neurogenic SUI. Continence rates and incidence of complications, revision and cuff erosion were evaluated. The outcomes in irradiated men were compared to those of non irradiated men. RESULTS: A total of 1277 patients who had an AUS met the inclusion criteria with a median age of 70 years, of which 437 had an history of prior radiotherapy. There was no difference in comorbidities. In irradiated patients, postoperative social continence, urethral atrophy and infection rates were respectively 75.6%, 2.4% and 9.5% and 76.8%, 5.4%, and 5.8% in nonirradiated men (respectively, p = 0.799, p = 0.128, p = 0.148). There were more urethral erosion in irradiated male patients. After a mean follow up of 36.8 months, the explantation free survival was poorer in irradiated patients (p = 0.001). CONCLUSION: These data suggest that pelvic radiotherapy before AUS adversely affect device survival with and increased greater occurrence of infection-erosion and therefore of explantation.

Cognitive-behavioral therapy and urge urinary incontinence in women. A systematic review.

INTRODUCTION AND HYPOTHESIS: UUI co-exists with numerous health conditions, having a substantial negative impact on health-related quality of life and mental health. Cognitive-behavioral therapy (CBT) could help patients manage these problems by changing the way they think and behave. METHODS: We carried out a systematic review of the literature assessing the modalities and effects of CBT as a stand-alone strategy, without adding PFMT, on symptoms and clinical signs, in women with UUI. Our secondary objective was to report modalities and effects of CBT on health-related quality of life, psychological symptoms and patient-reported satisfaction. The PRISMA methodology was used to carry out this systematic review. A literature search was conducted in PubMed, PEDro, Web of Science and Cochrane Library databases from inception to December 2020. The PICO approach was used to determine the eligibility criteria. RESULTS: Twelve papers were included in the present review which showed beneficial effects on both symptom severity (p < 0.05) and more subjective areas such as quality of life, psychological symptoms or patient satisfaction level (p < 0.05), respectively). However, results on the effectiveness of CBT on clinical signs remains conflicting. CONCLUSION: Based on the available literature, this review suggested a high level of evidence for the effectiveness of CBT on symptom severity and a moderate level of evidence for the effectiveness of CBT on quality of life, psychological symptoms and patient satisfaction. However, we highlighted no evidence for the effects of CBT on clinical signs.

Prevalence and Risk Factors of Artificial Urinary Sphincter Revision in Nonneurological Male Patients.

PURPOSE: The main objective of this study was to assess the prevalence and risk factors of male artificial urinary sphincter (AUS) mechanical failures and nonmechanical failures. MATERIALS AND METHODS: The charts of all male patients who underwent AUS implantation between 2004 and 2020 in 16 centers were retrospectively reviewed. Patients with neurogenic stress urinary incontinence (SUI) were excluded as well as revisions/explantations due to infections and/or erosions. The causes of revision were divided into mechanical failures (fluid loss or malfunction from any components of the AUS), nonmechanical failures (urethral atrophy, recurrence/persistence of SUI despite normally functioning device) and other (pump malposition, balloon herniation, hematoma, pain). Failure-free survival analysis was performed both for general and specific causes of revision. Predictors of mechanical and nonmechanical failures were determined by Cox proportional hazards model. RESULTS: A total of 1,020 patients met the inclusion criteria. After a median followup of 20 months, the estimated 5-year and 10-year overall revision-free survival was 60% and 40%, respectively. There were 214 AUS revisions: 59 (27.6%) for mechanical failures, 121 (56.5%) for nonmechanical failures and 34 (15.9%) other causes of revision. In multivariable Cox regression analysis, larger cuff size was the only predictor of overall revisions (HR=1.04 [1.01-1.07]; p=0.01) and revision for nonmechanical failure (HR=1.05 [1.02-1.09]; p=0.004). CONCLUSIONS: Half of the male AUS patients underwent device revision within the first 10 years after implantation. Nonmechanical failures are the primary cause of AUS revision in nonneurological men. Larger cuff size appears to be the main determinant of AUS revision risk.

Transcorporal vs. bulbar artificial urinary sphincter implantation in male patients with fragile urethra.

PURPOSE: To compare transcorporal vs bulbar artificial urinary sphincter (AUS) implantation in men with fragile urethra and to investigate the risk factors of AUS explantation in this population. METHODS: The charts of all male patients who had an AUS implantation between 2004 and 2020 in 16 centers were reviewed retrospectively. The primary endpoint was device explantation-free survival. Only patients with a fragile urethra were included in the present analysis. Fragile urethra was defined as a urethra carrying a high risk of cuff erosion because of prior radiotherapy and/or history of AUS explantation and/or history of urethral stricture surgery. The patients were divided in two groups according to the implantation site: bulbar vs transcorporal. RESULTS: 464 patients were included for analysis. 88 patients underwent a transcorporal AUS implantation and 376 underwent a bulbar AUS implantation. Explantation-free survival was similar in both groups (estimated 5-year explantation free survival rates 55.3% vs. 58.4%; p=0.98). In the subgroup of patients with a history of previous AUS explantation, transcorporal approach tended to bring longer explantation-free survival (2-year explantation-free survival: 61.9% vs. 58.2%; p=0.096). In multivariate analysis, the only risk factor of shorter explantation-free survival was the history of previous AUS explantation (HR=2.65; p=0.01). CONCLUSIONS: Transcorporal AUS implantation was not associated with longer explantation-free survival. History of previous AUS explantation was the only risk factor associated with shorter explantation-free survival and this subgroup of patients may be the only one to draw benefits of transcorporal AUS implantation.

State of the art on stress incontinence management after benign prostatic obstruction surgery.

PURPOSE OF REVIEW: Stress urinary incontinence (SUI) is mostly seen after prostate surgery (radical prostatectomy or benign prostatic obstruction [BPO] relief). As new surgical techniques (laser, endoscopic enucleation) have been dramatically expanded in the past decade, a focus on postoperative SUI is necessary to provide the best management in this iatrogenic situation. RECENT FINDINGS: Surgery is the main option for curative management of SUI after BPO as no oral medication is recommended. Preoperative work-up is mandatory to assess concomitant bladder dysfunction. All available surgical options (peri-urethral injections, periurethral balloons, various male slings, and artificial urinary sphincter) have been studied, but the level of evidence is very low. In this setting, SUI after BPO management is widely inspired from post-PR SUI management, mainly based on clinical experience. SUMMARY: The available literature regarding persistent SUI after BPO relief is very scarce and further studies are warranted in this specific population.

Robot-assisted artificial urinary sphincter implantation.

PURPOSE OF REVIEW: The aim of the present manuscript was to provide an overview on the current state of robotic artificial urinary sphincter (AUS) implantation in male and female patients. RECENT FINDINGS: Over the past few years, several series have been reported, with promising outcomes for the most part. This has contributed to expand the use of bladder neck AUS, especially in female patients, which was, until then, hampered by its perioperative morbidity. SUMMARY: Robotic AUS has been developed to overcome the technical challenge of bladder neck implantation in female patients and in specific male subgroups, especially self-catheterizing neurological patients. All the series of robotic AUS implantation published in the past few years reported much lower rates of cuff erosion and AUS explantation than the historical open cohorts suggesting that the robotic approach might become the standard for female AUS implantation. This less morbid approach along with technological improvement of the AUS device may contribute to make it a more popular option in the treatment of female stress urinary incontinence due to intrinsic sphincter deficiency. There are much less data available on robotic bladder neck AUS implantation in male patients.

Efficacy and tolerance of botulinum toxin injections after sacral nerve stimulation failure for idiopathic overactive bladder.

INTRODUCTION: Management of idiopathic overactive bladder (iOAB) after the failure of sacral nerve modulation (SNM) is very challenging. To the best of our knowledge, no study has evaluated the use of botulinum toxin A (BoNT-A) after SNM failure for iOAB. The aim of this study is to evaluate the tolerance and efficacy of BoNT-A injection after the failure of SNM for iOAB. METHODS: We conducted a retrospective multicentric analysis of all patients who had received either onabotulinumtoxinA or abobotulinumtoxinA intradetrusor injection for iOAB after SNM failure, between January 2004 and December 2017. The primary outcome was the percentage of success of first BoNT-A injection (either resolution of their urinary incontinence or their frequency or more than 50% reduction in frequency). Secondary outcomes were results of urodynamic studies, complications, total number of injections, causes of withdrawal, and subsequent treatment. RESULTS: Seventy-six patients (62 female) were included. The percentage of success of first BoNT-A injection was 43.4% (n = 33). All overactive bladder symptoms were significantly improved on the 3-day bladder diary. Twenty-eight patients (36.8%) were put under clean intermittent self-catheterization transitory. After a mean follow-up of 57.7 (±38.5) months, median number of injections was 2 (1-15). Overall, 42 patients (55.2%) stopped injections during follow-up. The estimated 36-months discontinuation-free rate was 48.1%. Mean cause of discontinuation was a primary failure (n = 32; 42.1%). CONCLUSION: BoNT-A can be used in SNM nonresponders with a success rate of 43.4% but is associated with a high long-term discontinuation rate.

Unilateral versus bilateral sacral neuromodulation test in the treatment of refractory idiopathic overactive bladder: A randomized controlled pilot trial.

AIM: To compare treatment success rate in terms of improvement of bladder overactivity between unilateral and bilateral sacral neuromodulation testing. METHODS: A multicentric, parallel, randomized, open pilot trial (October 2012-September 2017) was conducted. Participants presented primary overactive bladder resistant to first-line treatments. Patients were excluded in case of secondary bladder, pelvic, or neurological condition. Patients were randomized between bilateral testing (n = 28) or unilateral testing (n = 27), to determine the best functional response before final implantation. The primary outcome was the rate of patients presenting at least 50% of clinical improvement at 1 month on urinary frequency, number of urge incontinence episodes or number of urinary urgency episodes. Symptom severity, implantation success rate, uroflowmetry, device tolerance, complications, and quality of life were also assessed. RESULTS: Fifty-five patients have been included. The rate of patients presenting at least one significant clinical improvement at month 1 was 62% in the bilateral group versus 84% in the unilateral group (P = .0891), RR = 0.74 (0.51; 1.07). There was no significant difference between bilateral and unilateral groups in terms of improvement of urinary frequency (0% and 17%; P = .1115), number of urge incontinence episodes (52% and 63%; P = .4929) or number of urinary urgency episodes (57% and 74%; P = .2411). More complications were reported in the bilateral group than in the unilateral group (9 [47%] vs 4 [16%], respectively; P = .0239). CONCLUSION: Systematic bilateral sacral neuromodulation testing before final implantation did not appear to increase success rate compared with unilateral stimulation in the treatment of overactive bladder.

Long-Term Discontinuation of Botulinum Toxin A Intradetrusor Injections for Neurogenic Detrusor Overactivity: A Multicenter Study.

PURPOSE: Data are lacking on long-term outcomes of intradetrusor injections of botulinum toxin A for neurogenic detrusor overactivity. The aim of this study was to assess the outcomes of intradetrusor injections of botulinum toxin A for neurogenic detrusor overactivity after more than 10 years of followup. MATERIALS AND METHODS: We retrospectively reviewed the charts of all consecutive neurological patients who had received onabotulinumtoxin A or abobotulinumtoxin A intradetrusor injections for neurogenic detrusor overactivity between January 2002 and November 2007 at a total of 3 academic centers. The primary outcome measure was the 10-year discontinuation rate. Other outcomes of interest were failure, reasons for discontinuation and subsequent treatments of neurogenic detrusor overactivity. Discontinuation-free and failure-free survival was estimated by Kaplan-Meier analyses. RESULTS: A total of 140 patients were included in study. The 10-year discontinuation-free and failure-free survival rates were 49.1% and 73%, respectively. The most common reason for discontinuation was failure in 43.7% of cases, which was primary and secondary in 17.2% and 26.5%, respectively. Secondary failure occurred after a median of 8 injections and a median of 80.1 months from the first injection. Other reasons for discontinuation were patient decision in 28.1% of patients, nonbotulinum toxin A related improvement of urinary incontinence in 14.1%, neurological condition progression in 12.5% and an adverse event in 1.6%. Discontinuation-free survival was significantly poorer in patients with spina bifida than in patients with multiple sclerosis or spinal cord injury (p = 0.02). CONCLUSIONS: More than half of the patients with neurogenic detrusor overactivity discontinued intradetrusor botulinum toxin A within the first 10 years after the initial injection. Patients with spina bifida are at high risk for discontinuation.

Do patients have to choose between ejaculation and miction? A systematic review about ejaculation preservation technics for benign prostatic obstruction surgical treatment.

PURPOSE: Ejaculatory dysfunction is the most common side effect related to surgical treatment of benign prostatic obstruction (BPO). Nowadays, modified surgical techniques and non-ablative techniques have emerged with the aim of preserving antegrade ejaculation. Our objective was to conduce a systematic review of the literature regarding efficacy on ejaculatory preservation of modified endoscopic surgical techniques, and mini-invasive non-ablatives techniques for BPO management. METHODS: A systematic review of the literature was carried out on the PubMed database using the following MESH terms: "Prostatic Hyperplasia/surgery" and "Ejaculation", in combination with the following keywords: "ejaculation preservation", "photoselective vaporization of the prostate", "photoselective vapo-enucleation of the prostate", "holmium laser enucleation of the prostate", "thulium laser", "prostatic artery embolization", "urolift", "rezum", and "aquablation". RESULTS: The ejaculation preservation rate of modified-TURP ranged from 66 to 91%. The ejaculation preservation rate of modified-prostate photo-vaporization ranged from 87 to 96%. The only high level of evidence studies available compared prostatic urethral lift (PUL) and aquablation versus regular TURP in prospective randomized-controlled trials. The ejaculation preservation rate of either PUL or aquablation compared to regular TURP was 100 and 90 versus 34%, respectively. CONCLUSIONS: Non-ablative therapies and modified endoscopic surgical techniques seemed to be reasonable options for patients eager to preserve their ejaculatory functions.

AMS-800 Artificial urinary sphincter in female patients with stress urinary incontinence: A systematic review.

AIMS: To perform a systematic review of studies reporting the outcomes of AMS-800 artificial urinary sphincter (AUS) implantation in female patients with stress urinary incontinence (SUI) resulting from intrinsic sphincter deficiency (ISD). METHODS: A systematic literature search of the Medline and Embase databases was performed in June 2018 in accordance with the PRISMA statement. No time limit was used. The protocol was registered in PROSPERO (CRD42018099612). Study selection and data extraction were performed by two independent reviewers. RESULTS: Of 886 records screened, 17 were included. All were retrospective or prospective non-comparative case series. One study reported on vaginal AUS implantation, 11 on open AUS implantation, two on laparoscopic AUS implantation, two on robot-assisted AUS implantation and one compared open and robot-assisted implantations. The vast majority of patients had undergone at least one anti-incontinence surgical procedure prior to AUS implantation (69.1-100%). The intraoperative bladder neck injury rates ranged from 0% to 43.8% and the intraoperative vaginal injury rates ranged from 0 to 25%. After mean follow-up periods ranging from 5 to 204 months, the complete continence rates ranged from 61.1% to 100%. The rates of explantation, erosion and mechanical failure varied from 0% to 45.3%, 0% to 22.2% and 0% to 44.1%, respectively. CONCLUSIONS: AMS-800 AUS can provide excellent functional outcomes in female patients with SUI resulting from ISD but at the cost of a relatively high morbidity. High level of evidence studies are needed to help better define the role of AUS in the female SUI armamentarium.
