RESUMO
OBJECTIVES: To assess the correlation between the response to transcutaneous tibial nerve stimulation (TTNS) and subsequent response to sacral nerve modulation (SNM) to treat overactive bladder (OAB). MATERIALS AND METHODS: All patients who consecutively received TTNS followed by a two-stage SNM between January 2016 and June 2022 to treat OAB in two university hospital centers were included. The response to each therapy was evaluated with success defined by a 50% or greater improvement in one or more bothersome urinary symptoms from baseline. The primary endpoint was the statistical relationship between the response to TTNS and the response to SNM, assessed by logistic regression. Secondary endpoints were the statistical relationship between the response to TTNS and the response to SNM when controlling for gender, age (<57 years vs. >57 years), presence of an underlying neurological disease, and presence of DO, adding the factor and interaction to the previous regression model. RESULTS: Among the 92 patients enrolled in the study, 68 of them were women (73.9%), and the median age was 57.0 [41.0-69.0] years. The success was reported in 22 patients (23.9%) under TTNS and 66 patients (71.7%) during the SNM test phase. There was no statistical correlation between response to TTNS and response to SNM in the overall population (confidence interval: 95% [0.48-4.47], p = 0.51). Similarly, there was no statistical correlation when controlling for age <57 years or ≥57 years, with p = 1.0 and p = 0.69, respectively. No statistical study could be conducted for the other subpopulations due to small sample sizes. CONCLUSION: The response to TTNS does not predict the response to SNM in the treatment of OAB. TTNS and SNM should be considered as separate therapies, and the decision-making process for OAB treatment should take this into account.

AIMS: To address the predictive factors of a successful voiding after bladder outflow resistance reduction surgery (BORRS) in men presenting with acute or chronic urinary retention (UR). METHODS: A think tank (TT) of ICI-RS was gathered in 2023, Bristol, UK, to discuss several aspects of the problem, such as the pathophysiology of UR, the clinical and urodynamic evaluation of men with UR and whether it is possible to predict which men will be able to successfully void after treatment with contemporary surgical options. RESULTS: The TT agreed that successful voiding after BORRS depends on several factors but that a strong recommendation cannot be made regarding preoperative evaluation and whether there are predictive factors of success because of the heterogeneity of patients and methodology in published trials. The diagnosis of obstruction in men with UR may be challenging when there is apparent reduced detrusor contraction during urodynamic studies. Even in the absence of bladder contractility there is documentation of such cases that have voided adequately after BORRS. Still, detrusor underactivity and inadequate relief of prostatic obstruction are the main causes of an unsuccessful voiding after BORRS. Conventional resection and enucleation methods remain the most successful surgeries in relieving UR in men, whereas the efficacy of minimally invasive surgical treatments needs to be assessed further. CONCLUSION: Research is needed to understand the pathophysiology of UR and the predictors of successful voiding after different types of BORRS in men with UR.

PURPOSE: We assess the efficacy, safety, and predictive factors for failure of synthetic mid-urethral slings for the treatment of urinary incontinence in a large cohort of women with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: Women aged 18 years or older who received a synthetic mid-urethral sling for stress urinary incontinence or mixed urinary incontinence in 3 centers between 2004 and 2019 and who had a neurological disorder were included. Exclusion criteria were less than 1 year of follow-up, concomitant pelvic organ prolapse repair, previous synthetic sling implantation, and no baseline urodynamics. The primary outcome was surgical failure, defined as recurrence of stress urinary incontinence during follow-up. Kaplan-Meier analysis was used to estimate the 5-year failure rate. Adjusted Cox proportional hazard model was used to identify factors associated with surgical failure. Complications and reoperations during the follow-up have also been reported. RESULTS: A total of 115 women with a median age of 53 years were included. The median follow-up duration was 75 months. The 5-year failure rate was 48% (95 CI 46%-57%). Age above 50 years, negative tension-free vaginal tape test and transobturator route were associated with surgical failure. Thirty-six patients (31.3%) underwent at least 1 reoperation for complications or failure, and 2 required definitive intermittent catheterization. CONCLUSIONS: Synthetic mid-urethral slings may be an acceptable alternative to autologous slings or artificial urinary sphincters for the treatment of stress urinary incontinence in a selected group of patients with neurogenic lower urinary tract dysfunction.

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.

BACKGROUND: Central sensitization is frequently associated with chronic pelvic pain and requires specific management. The pain is described as hypersensitivity to an innocuous stimulus that is both widespread and persistent. However, no study has evaluated if central sensitization can be measured objectively with neurophysiological tests in the pelvic and perineal area to prove this concept in women with chronic pelvic pain. OBJECTIVE: This study aimed to evaluate nociceptive thresholds (primary objective) and spatial and temporal diffusion of pain among women with chronic pelvic pain and high or low scores of central sensitization. STUDY DESIGN: This prospective, assessor-blinded, comparative study compared a cohort of women with chronic pelvic pain and a high (>5/10; n=29) vs low (<5/10; n=24) score of sensitization according to the Convergences PP criteria. Participants underwent a noninvasive bladder sensory test, a rectal barostat test, and a muscular (algometer) and a vulvar (vulvagesiometer) sensory test. Poststimulation pain (minutes), quality of life (Medical Outcomes Study 36-Item Short Form Survey), and psychological state, comprising anxiety (State-Trait Anxiety Inventory), depression (Beck Depression Inventory Short Form), and catastrophizing (Pain Catastrophizing Scale), were assessed. RESULTS: The participants mostly suffered from endometriosis (35.8%), irritable bowel syndrome (35.8%), bladder pain syndrome (32.1%), and vestibulodynia (28.3%). Baseline characteristics were similar. Women with a high sensitization score had more painful diseases diagnosed (2.7±1.3 vs 1.6±0.8; P=.002) and suffered for longer (11±8 vs 6±5 years; P=.028) than participants with a low score. The bladder maximum capacity was equivalent between participants (399±168 vs 465±164 mL; P=.18). However, the pain felt at each cystometric threshold was significantly increased in women with a high sensitization score. No difference was identified for the rectal pain pressure step (29.3±5.5 vs 30.7±6.5 mm Hg; P=.38). Rectal compliance was decreased in women with a high sensitization score with a considerable increase in pain felt. The average of pain pressure thresholds at the 5 vulvar sites tested was decreased in these participants (162.5±90.5 vs 358.7±196.5 g; P=.0003). Similar results were found for the average of the pain pressure thresholds at 6 muscles tested (1.34±0.41 vs 2.63±1.52 kg/m2; P=.0002). A longer period was needed for patients with high sensitization score to obtain a VAS <3 out of 10 after the stimulation of the bladder (4.52±5.26 vs 1.27±2.96 minutes; P=.01), the rectum (3.75±3.81 vs 1.19±1.23 minutes; P=.009), and the muscles (1.46±1.69 vs 0.64±0.40 minutes; P=.002). The psychological state was equivalent between groups. No association was found between the sensory thresholds and the psychological state results. The physical component of the quality of life score was reduced in women with high sensitization score (P=.0005), with no difference in the mental component. CONCLUSION: Using neurophysiological tests, this study showed that there are objective elements to assess for the presence of central sensitization, independently of psychological factors.

PURPOSE: To assess the morbidity of inguinal lymph node dissection (ILND) in penile cancer, then to compare this morbidity with that of ILND performed in the context of skin cancer treatment. METHODS: We retrospectively included all patients having undergone ILND between 1 January 2004 and 31 December 2019 in our centre's urology department in the context of treatment of penile cancer or skin cancer. Postoperative complications were reported in accordance with the Clavien-Dindo classification system. RESULTS: Two hundred forty-two ILNDs were performed in 122 patients with penile cancer and 56 ILNDs were performed in 56 patients with skin cancer. The most common early complication was postoperative fluid collection (lymphocele or haematoma), which complicated 44% of ILNDs overall and 60% of radical lymphadenectomies. The most common late complication was leg lymphoedema, found in up to 36% of radical lymphadenectomies. Major complications (grade ≥ III) were very rare (4% of radical lymphadenectomies). Radical lymphadenectomies resulted in significantly more cases of postoperative fluid collection, skin necrosis and dehiscence, as well as leg lymphoedema, than modified lymphadenectomy techniques. Two factors significantly increasing postoperative morbidity were demonstrated: ASA score = 3 (OR = 3.09) and operating time (OR = 1.01). CONCLUSION: ILNDs are morbid surgical procedures for which the indications must be well defined. However, the complications are almost exclusively minor, for a major oncological benefit.

PURPOSE: In 95% of cases, penile cancer is a squamous cell carcinoma whose specificity is lymphatic spread with the inguinal lymph nodes as the first relay route. Inguinal lymph node dissection is a primordial part of the treatment. The objective was to assess the oncological results of inguinal lymph node dissection in penile cancer at our centre. METHODS: We retrospectively included all patients having undergone inguinal lymph node dissection at our centre between 1 January 2004 and 1 January 2020 for the treatment of penile cancer. Patients for whom lymphadenopathy was palliative were excluded. Depending on indications, the procedures consisted in either dynamic sentinel node biopsy, modified lymphadenectomy or radical lymphadenectomy. All cancers were reclassified using the 2016 TNM classification system. Survival was analysed according to the Kaplan-Meier method. RESULTS: 242 inguinal lymph node dissections were performed in 122 patients. There were 71 pN0 (58%), 9 pN1 (7%), 4 pN2 (3%) and 38 pN3 (31%). Mean follow-up was 51 ± 45 months. The 3-year recurrence-free survival rate was 76% in pN0 patients and 17% in pN3 patients. The 5-year specific and overall survival rates were, respectively, 82% and 73% for pN0 stages, and 14% and 17% for pN3 stages. Extracapsular extension on an inguinal lymphadenopathy appeared as a highly negative prognostic factor. CONCLUSION: Inguinal lymph node dissection is essential in the treatment of penile cancer. Recurrence-free, specific and overall survival are closely linked to the lymph node stage. Extracapsular extension and pelvic lymph node invasion are highly negative prognostic factors.

PURPOSE: This study aimed to seek predictive factors and develop a predictive tool for sacral nerve modulation (SNM) implantation in patients with non-obstructive urinary retention and/or slow urinary stream (NOUR/SS). METHODS: This study was designed as a retrospective study including all patients who have undergone a two-stage SNM for NOUR/SS between 2000 and 2021 in 11 academic hospitals. The primary outcome was defined as the implantation rate. Secondary outcomes included changes in bladder emptying parameters. Univariate and multivariable logistic regression analysis were performed and determined odds ratio for IPG implantation to build a predictive tool. The performance of the multivariable model discrimination was evaluated using the c-statistics and an internal validation was performed using bootstrap resampling. RESULTS: Of the 357 patients included, 210 (58.8%) were finally implanted. After multivariable logistic regression, 4 predictive factors were found, including age (≤ 52 yo; OR = 3.31 CI95% [1.79; 6.14]), gender (female; OR = 2.62 CI95% [1.39; 4.92]), maximal urethral closure pressure (≥ 70 cmH2O; OR: 2.36 CI95% [1.17; 4.74]), and the absence of an underlying neurological disease affecting the lower motor neuron (OR = 2.25 CI95% [1.07; 4.76]). Combining these factors, we established 16 response profiles with distinct IPG implantation rates, ranging from 8.7 to 81.5%. Internal validation found a good discrimination value (c-statistic, 0.724; 95% CI 0.660-0.789) with a low optimism bias (0.013). This allowed us to develop a predictive tool ( https://predictivetool.wixsite.com/void ). CONCLUSION: The present study identified 4 predictive factors, allowing to develop a predictive tool for SNM implantation in NOUR/SS patients, that may help in guiding therapeutic decision-making. External validation of the tool is warranted.

PURPOSE: To report long-term results of artificial urinary sphincter implantation for urinary incontinence due to intrinsic sphincter deficiency in children. MATERIALS AND METHODS: This retrospective monocentric study included all patients who underwent artificial urinary sphincter (AMS 800) implantation before 18 years of age between 1986 and October 2018 for intrinsic sphincter deficiency. The primary outcome was the continence rate at the last follow-up, defined by the daily use of 0 pads. The secondary outcome was the overall survival of the device, defined as the absence of any repeated surgery (revision or explantation) during follow-up. Reoperation-free, revision-free, and explantation-free device survival rates were estimated using the Kaplan-Meier method. RESULTS: Thirty-six patients with a median age of 12 years (interquartile range [IQR]: 10-14) were included (15 females, 21 males). The median follow-up was 18.7 years (IQR: 9-26). The main underlying condition was spinal dysraphism (n = 24; 67%). The median time to the first reoperation was 9 years (IQR: 3.75-14.7). At the last follow-up, survival rates without revision were 84%, 71%, 55%, and 33% at 5, 10, 15, and 20 years, respectively. Survival rates without explantation were 91%, 84%, 80%, and 72% at 5, 10, 15, and 20 years, respectively. At the last follow-up, 29 patients had a functional device. The overall continence rate was 88%. All patients who had their device still in place were continent at the last follow-up. CONCLUSION: The artificial urinary sphincter is an effective long-term treatment for urinary incontinence related to intrinsic sphincter deficiency in children, providing a high rate of continence, even if associated with a high rate of reoperation.

OBJECTIVES: The aim of this study was to assess midterm functional outcomes and complications of robot-assisted laparoscopic cystectomy with non-continent urinary diversion in patients with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: We performed a retrospective single center study including all patients who underwent robot-assisted laparoscopic cystectomy with non-continent urinary diversion between January 2008 and December 2018 for neurogenic lower urinary tract dysfunction. Perioperative data, early and late complications, reoperation rate, renal function, and patient satisfaction (PGI-I) were evaluated. RESULTS: One hundred and forty patients were included (70 multiple sclerosis, 37 spinal cord injuries, 33 others) with a median follow-up of 29 months (12-49). The main indication for surgery was an inability to perform intermittent self-catheterization (n = 125, 89%). The early complication rate (<30 days) was 41% (n = 58), including 72% (n = 45) minor complications (Clavien I-II) and 29% (n = 17) major complications (Clavien III-V). Three patients died in the early postoperative period. Late complications appear in 41% (n = 57), with 9% (n = 13) being ureteroileal anastomotic stricture. The overall reintervention rate was 19% (n = 27), mainly for lithiasis surgery. Pre- and postoperative renal function were comparable. Most of patients reported an improvement in their quality of life following their surgery (PGI-I 1-2). CONCLUSION: Robot-assisted laparoscopic cystectomy with non-continent urinary diversion may be of particular interest in patients with neurogenic lower urinary tract dysfunction who are unable to benefit from conservative treatment, as it provides midterm protection of the upper urinary tract and an improvement in quality of life.

INTRODUCTION: The underlying pathophysiology behind a diagnosis of acontractile or underactive detrusor at invasive urodynamics is very heterogeneous. Lack of etiological classification currently limits the possibility of stratifying therapy. METHODS: This subject was discussed at a think-tank on the subject at the International Consultation on Incontinence-Research Society held in Bristol, June 2023. This manuscript is a result of those deliberations and the subsequent discussions of the think-tank. RESULTS: There are challenges in defining abnormalities of detrusor contraction with resultant implications for available evidence. Pathology at any level of the neuromuscular pathway can impair or prevent a detrusor voiding contraction. Attempts have been made to identify clinical markers that might predict an underactive detrusor but strong supporting evidence is lacking. Hence, a holistic approach to phenotyping requires specialized neuro-imaging as well as physiological investigations. Several general measures can help individuals with an abnormal detrusor contraction. The search for a molecule to enhance the detrusor voiding contraction remains elusive but there are promising new candidates. Neuromodulation can help select individuals but data is not well stratified by underlying etiology. Manipulation of central neurotransmitters might offer an alternate therapeutic option. CONCLUSIONS: A better understanding of the underlying pathophysiologies behind an abnormality of the detrusor voiding contraction is needed for improving management. Towards this goal, the think-tank proposes a classification of the underactive detrusor that might help in selecting and reporting more well-defined patient cohorts.
RESUMO
OBJECTIVES: Several central nervous system (CNS) centers affect muscle groups of the lower urinary tract (LUT) and anorectal tract (ART) via autonomic and somatic pathways, working in different modes (storage or expulsion). Hence spinal cord dysfunction can affect the LUT and ART by several possible mechanisms. METHODS: This review reports the discussions of a workshop at the 2023 meeting of the International Consultation on Incontinence Research Society, which reviewed uncertainties and research priorities of spinal dysfunction. RESULTS: Discussion focussed on the levator ani nerve, mechanisms underpinning sensory function and sensation, functional imaging, dyssynergia, and experimental models. The following key research questions were identified. (1) Clinically, how can we evaluate the levator ani muscle to support assessment and identify prognosis for effective treatment selection? (2) How can we reliably measure levator ani tone? (3) How can we evaluate sensory information and sensation for the LUT and the ART? (4) What is the role of functional CNS imaging in development of scientific insights and clinical evaluation? (5) What is the relationship of detrusor sphincter dyssynergia to renal failure? CONCLUSIONS: Spinal cord dysfunction can fundamentally disrupt LUT and ART function, with considerable clinical impact. The evaluation needs to reflect the full scope of potential problems, and new clinical and diagnostic approaches are needed, for prognosis and treatment. The preclinical science evaluating spinal cord function in both LUT and ART storage and elimination remains a major priority, even though it is a challenging experimental context. Without this underpinning evidence, development of new clinical evidence may be held back.
RESUMO
INTRODUCTION AND HYPOTHESIS: To assess the effectiveness, safety and risk factors of failure and complications associated with Adjustable Continence Therapy (ACT®) balloons as a treatment for female stress urinary incontinence (SUI). METHODS: In the present multicentric retrospective study, all women implanted with ACT® balloons between 2000 and 2018 were considered eligible. Effectiveness and safety were assessed at 1 year, and risk factors for failure and complications were sought. The effectiveness was categorized into three distinct groups: Success = maximum 1 pad/day and patient's impression of improvement using a numerical rating scale (NRS) ≥ 8/10; Improvement = decrease of daily pad use and NRS ≥ 5/10; Failure = increase or stability of daily pad use or NRS < 5/10. The intra- and postoperative surgical complications were collected. RESULTS: Over the study period, 281 women were included. Among them, 104 (37.0%), 94 (33.5%) and 83 (29.5%) were categorized as success, improvement, and failure, respectively. Intra-, early and late postoperative complications occurred in 13 (4.6%), 35 (12.5%) and 75 (26.7%) women, respectively. Most early surgical complications were minor according to the Dindo-Clavien classification. Of women that presented a late postoperative surgical complication, 64 (22.8%) underwent an explantation performed under local or general anesthesia without associated sequalae. CONCLUSIONS: The short-term effectiveness associated with ACT® balloons, their minimally invasive implantation and the frequent but easily manageable and sequelae-free complications suggest that they should be part of the therapeutic arsenal for female SUI.

OBJECTIVES: The aim of our study was to evaluate the morbidity and mortality, as well as the oncogical results of patients who had undergone surgical procedure for a kidney cancer with thrombus extension into the inferior vena cava. MATERIALS AND METHODS: Between January 2004 and April 2020, 57 patients were operated by enlarged nephrectomy with thrombectomy for kidney cancer with thrombus extension in the inferior vena cava. Twelve patients (21%) with the use of cardiopulmonary bypass because the thrombus was upper than the sus-hepatic veins. Twenty-three patients (40.4%) were metastatic at diagnosis. RESULTS: Perioperative mortality was 10.5%, without difference according to surgical technique. Morbidity during hospitalization was 58%, without difference according to surgical technique. Median follow-up was 40.8±40.1months. Overall survival at 2 and 5years was 60% and 28%, respectively. At 5years, the principal prognostic factor was the metastatic status at diagnosis, in multivariate analysis (OR: 0.15, P=0.03). Progression free survival mean was 28.2±40.2months. Progression free survival at 2 and 5years was 28% and 18%, respectively. All the patients who were metastatic at diagnosis had a recurrence in an average time of 5.7months (median of 3months). Thirteen percent of patients can be considered cured at the end of the study. CONCLUSION: Morbidity and mortality of this surgery remain important. The metastatic status at diagnosis has appeared to be the principal prognostic factor on the survival of these patients. LEVEL OF EVIDENCE: Level 4: retrospective study.

BACKGROUND: After two consecutive kidney transplant failures, a third kidney transplantation improves survival for patients on the waiting list. The surgical outcomes and complications of third kidney transplantations remain poorly known. METHODS: We analyzed the last 100 third kidney transplantations performed in our center between January 2000 and August 2018. The data, relating to donors and recipients, were extracted retrospectively from medical records and from the prospective DIVAT database (computerized and validated data in transplantation). Continuous variables are expressed as means, medians, first and third quartiles (median, [Q1;Q3]). Categorical variables are expressed as percentages. Patient and transplant survivals were calculated using the Kaplan-Meier method. RESULTS: Mean age of recipients was 46.4 years (47, [36;53]). Thirty-five percent had kidney failure due to urinary tract malformations. Mean age of donors was 48.2 years (52, [39.75; 58]) with 63% of donors with standard criteria. Mean cold ischemia time was 22.4hours (21, [16.5; 29.2]). Surgical mortality rate was 2% and surgical complication rate was 45%. Third kidney transplants survival was 73.1% and 58.8% at 5 years and 10 years. Mortality rate with a functioning transplant was 18%. CONCLUSION: A third kidney transplant offers satisfactory functional outcomes but remains associated with high morbi-mortality and a significant death rate with a functioning transplant.

PURPOSE: The current health crisis has drastically impacted patient management in many fields, including neuro-urology, leading to a mandatory reorganization. The aim of this work was to establish guidelines regarding the prioritization and optimal timing of each step of neurogenic lower urinary tract dysfunction management. METHODS: A steering committee included urologists and physical medicine and rehabilitation practitioners. Based on a literature review and their own expertise, they established a comprehensive risk-situation list and built a risk scale, allowing multiple other experts to score each clinical situation. New recommendations were generated using a Delphi process approach. RESULTS: Forty-nine experts participated in the rating group. Among the 206 initial items, 163 were selected and divided into four domains, diagnosis and assessment, treatment, follow-up, and complications, and two sub-domains, general (applicable for all neurological conditions) and condition-specific [varying according to the neurological condition (spinal cord injury, multiple sclerosis, brain injury, Parkinsonism, dysraphism, lower motor neuron lesions)]. The resulted guidelines are expert opinions established by a panel of French-speaking specialists, which could limit the scalability of this work. CONCLUSIONS: The present multidisciplinary collaborative work generates recommendations which complement existing guidelines and help clinicians to reorganize their patients' list in the long term with a personalized medicine approach, in the context of health crisis or not.

PURPOSE: To assess the efficacy and safety of intradetrusor botulinum toxin type A injections (IBTI) for idiopathic overactive bladder (iOAB) in non-neurological adults with an artificial urinary sphincter (AUS). MATERIALS AND METHODS: We retrospectively selected, in the 11 French centers, members of a collaborative network (GENULF (Groupe d'étude de neuro-urologie de langue francaise)), the patients who had had an artificial urinary sphincter implantation and who had subsequently developed iOAB requiring IBTI. This study was approved by the French association of urology ethics committee (no 2018012). RESULTS: Between 2006 and 2020, 33 patients were included from 5 French centers. Mean follow-up after the first IBTI was 47 months. The average age of the studied population was 68 years, with 70% of females. A complete resolution of symptoms at optimal IBTI dose was experienced by 21 (64%) patients. Seven (21%) patients had partial improvement. Five non-responder patients (15%) had no improvement at all. Maximum cystometric bladder capacity was 240 ml pre-IBTI and 335 ml post IBTI. Discontinuation free survival at 60 months was 50%. Two erosions occurred during the 6 months following an IBTI both in male patients with a perineal implantation. There were four AUS balloon perforations that occurred during the 6 months following an IBTI, all of them in female patients. CONCLUSIONS: IBTI has a good efficacy for the treatment of iOAB in patients with an AUS. However, both patients and practicians must be aware of the risk of rare and usually mild complications.

PURPOSE: To establish whether the expression of markers of cell differentiation (CK7, CK14, CK20, GATA3), apoptosis (p53), proliferation (Ki67, STAG2) and peri-tumoural lymphocytes (CD3, CD8), provides specific information about urothelial carcinogenesis in neuro-urological patients with bladder cancer (NBC). METHODS: Tissue samples from NBC were retrieved from 15 centres in France and compared to control samples from non neuro-urological patients with bladder cancer (NNBC) and from neuro-urological patients without bladder cancer (NB). The expression of CK7, CK14, CK20, GATA3, p53, Ki67, STAG2, CD3 and CD8 markers was analysed using immunohistochemistry of tissue microarray sections. RESULTS: Overall, tissue samples from 124 patients were included in the study (n = 72 NBC, n = 26 NNBC and n = 26 NB). Muscle invasive bladder cancer (MIBC) was found in 52 NBC patients (72.2%) and squamous cell differentiation in 9 (12.5%). In NBC samples, the expression of CK20 and GATA3 was significantly more frequent in NMIBC compared to MIBC (p = 0.015 and p = 0.004, respectively). CK20 and GATA3 were significantly more expressed in NBC compared to NNBC (p < 0.001 and p = 0.010, respectively). The expression of CK14, Ki67, CD3 and CD8 was significantly more frequent in NBC than in NNBC samples (p = 0.005, p < 0.001, p < 0.001 and p < 0.001, respectively). The expression of CD3 and CD8 was similar in NBC and NB samples. CONCLUSION: In NBC, markers of basal differentiation, proliferation and peri-tumoural lymphocytes were significantly more expressed compared to NNBC controls. These results suggest the aggressiveness of NBC and the role of chronic inflammation in the carcinogenesis of bladder cancer in neuro-urological patients.

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.

OBJECTIVE: The objective of this study was to assess the mid-term efficacy and safety of adjustable continence therapy (ProACT™) for the treatment of male stress urinary incontinence (SUI) after radical prostatectomy (RP). PATIENTS AND METHODS: Single-center retrospective study including male patients implanted with ProACT™ periurethral balloons for SUI after RP between 2007 and 2017, mainly with flexible cystoscopic guidance. Efficacy was assessed using a composite endpoint with subjective (patient's impression of improvement (PII), using a 0-100 numeral rating scale) and objective outcomes (decrease in daily pad use). Postoperative success was defined as a PII ≥ 80%, associated with the use of 0-1 pad daily. Improvement was defined as a PII ≥ 50% and a decrease ≥50% in the number of daily pads used. RESULTS: Two hundred men with a median age of 68 (64-73) years were included. Seventeen percent (n = 34) had had prior radiotherapy and 15.5% (n = 31) had had prior SUI surgery. The median follow-up was 43 (19-71) months. The severity of SUI was as follows: mild in 119 (59.5%), moderate in 48 (24%), and severe in 33 patients (16.5%). Severe SUI and a history of prior radiotherapy were associated with a lower success rate (p = 0.033 and p < 0.0001). The overall reoperation rate was 34%, with 5.6% (n = 11) requiring a third implantation. Of the patients, 29.4% (n = 58) required an artificial urinary sphincter to treat SUI. At the last follow up, among the overall population, the success rate was 40.1% and the median PII was 18.3%. For patients in whom the balloons were still in place (n = 132), the cumulative success and improvement rate was 78%, with a median PII of 72%. CONCLUSION: The minimally invasive ProACT™ device provides a clear beneficial continence outcome in patients with SUI after radical prostatectomy. Severe SUI or prior radiotherapy were associated with a lower success rate in our study.
