RESUMEN
PURPOSE: To compare the quality of life (QoL) in the same patients first treated with botulinum toxin A (BTA) injections for neurogenic detrusor overactivity (NDO) and then with bladder augmentation (BA). METHOD: Retrospective study of patients who had BA after BTA treatment between January 2012 and December 2022. Qualiveen Short Form questionnaires and a 7-level Likert/PGI-I scale to answer the question "How would you describe your quality of life after surgery compared to when you felt your best with BTA injections?" were collated and analyzed. RESULTS: Fifty-two BAs for neurogenic bladder (NDO or low compliance) were performed in patients with a median age of 43years [33; 52] previously treated with BTA. After a median follow-up of 33.5 [13.8; 54.3] months, the median Qualiveen-SF global score after BA was significantly higher than that obtained at best BTA efficacy (1.63 [1; 2.63] vs. 2.63 [1.88; 3], P=0.012), as were the scores for the fear, constraints/restrictions and limitations/inconvenience domains. The median PGI-I score was +3 [2; 3] (truly better QoL) and 85.4% of patients reported a QoL after BA superior to the best QoL under BTA. CONCLUSION: BA provides a greater range of QoL improvement than BTA injection for patients who have experienced both treatments. Long-lasting effects and absence of need to perform iterative retreatment were the main reasons.
RESUMEN
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 evaluate the incidence of vesicovaginal fistula (VVF) in France. METHODS: We conducted a retrospective analysis of prospectively and systematically collected data from January 2010 to December 2018 in the French Hospital Discharge Database. We used ICD-10 code "N820" to identify new VVF diagnoses. VVF incidence was calculated using estimations of the French population. We compared age on diagnosis, medical history of pelvic tumoral disease, radiotherapy, hysterectomy and childbirth, according to three subgroups: surgical repair attempt (SRA), long-term catheter and/or nephrostomies (LTC) or immediate surgical urinary diversion (ISUD). We focused on the patients diagnosed in 2017 to better analyse VVF aetiologies and outcomes (7-year hindsight and 1 year of follow-up). Chi-squared and Kruskal-Wallis tests were, respectively, used for qualitative and quantitative data comparisons. RESULTS: Of the 196 million hospital stays out of 50 million French citizens hospitalised from 2010 to 2018, 5499 women were hospitalised for VVF. The estimated incidence of VVF was 2.3/100,000 women-year. Approximately half of the patients underwent SRA (48.4%); 39.8% had LTC and 11.9% had ISUD. Patients were younger in the SRA subgroup (53.4 ± 14.7 years p < 0.001) with a lower rate of pelvic cancer (p < 0.001) or radiotherapy (p < 0.001) and a higher rate of hysterectomies (p > 0.001). In 2017, two-thirds of the VVF diagnosed were secondary to pelvic surgery. Mean management time was 9.2 ± 10.6 months. After SRA, 5.4% underwent incontinence surgery and 5.0% underwent secondary surgical urinary diversion. CONCLUSIONS: VVF is not a rare pathology in France, mainly due to pelvic surgery. Its management is complex and not well defined.

OBJECTIVE: To compare the perioperative complications of patients who underwent flexible ureteroscopy (fURS) for the treatment of urolithiasis according to the type of ureteroscope used, single-use (suURS) or reusable (rURS) flexible ureteroscope. PATIENTS AND METHODS: A retrospective and single-center study was conducted between January 2017 and May 2019, including all fURS performed for nephrolithiasis management. During the study period, 5rURS and 1suURS (UscopePU3022) were available. The primary endpoint was the occurrence of 30-days postoperative complications, especially infectious complications, classified according to Clavien-Dindo grading system. RESULTS: Overall, 322 consecutive fURS were included corresponding to 186 rURS (57.8%) and 136 suURS (42.2%). Respectively in rURS and suURS groups, the median (IQR) age was 57 (45-65) vs 57 (44-66) years (p=0.75), 83 (44.6%) vs 63 (46.3%) female were included (p=0.82), and median (IQR) Charlson score was 2 (1-3) vs 2 (0-3) (p=0.15). Fifty-one patients (15.8%) developed postoperative complications, 28 patients (15%) in rURS group and 23 patients (17.6%) in suURS group (p=0.64). Most of them (n=47, 92.1% of overall complications) were minor (Clavien I-II). Occurrence of urinary tract infection in suURS group (n=13; 9.5%) was equally comparable with rURS group (n=10; 5.4%), p=0.15. CONCLUSIONS: Our data suggests that suURS represents a safe alternative to rURS. Compared to reusable devices, UscopePU3022 use was associated with a similar complication rates, however, did not decrease the occurrence of infectious events.

OBJECTIVE: To report a contemporary series of Miami pouch (MP) enriched with a full technical description and step-by-step video to contribute to wider use. PATIENTS AND METHODS: A retrospective charts review of all patients who had a MP at our center between January 2016 and December 2017 was performed. The MP technique uses the terminal 15cm of ileum and the right colon to build an intestinal heterotopic pouch located in the right iliac fossa and connected to the skin by an efferent catheterizable tube. Primary outcome was continence defined as the absence of leakage between clean intermittent self-catheterization (CISC) with a maximal interval of 4 hours between each CISC. RESULTS: Fifteen patients had MP during the study period. Thirty-day postoperative Clavien III complications were observed in 2 (13.3%) patients. At 39 months of median follow-up, continence was obtained for all patients except for 2 patients whom reported intermittent night-time leakages due to long intervals (5 to 7 hours) between 2 CISC. No significant alteration of renal function was reported and no stenosis of the efferent tube neither difficulty to perform CISC was observed. CONCLUSIONS: For patients who are candidates for radical cystectomy and not eligible for orthotopic neobladder, intestinal heterotopic pouch with a cutaneous continent urinary diversions as MP may be a reliable alternative. Patients should be informed of the existence of a valid alternative to ileal conduit since it may fit their expectations of a preserved body image without urine collecting appliances.

Objectives: To evaluate the risk of residual tumor and tumor upstaging during a second resection after primary complete transurethral resection of bladder tumor (TURBT) using photodynamic diagnosis (PDD) for high-risk nonmuscle invasive bladder cancer (NMIBC). Patients and Methods: From January 2014 to March 2020, a single-institutional study was conducted including consecutive patients with high-risk NMIBC (T1 and/or cis and/or high grade) who underwent a restaging transurethral resection (reTUR) within 12 weeks after a primary complete resection. Each TURBT was performed using blue light after intravesical instillation of hexaminolevulinate. The primary endpoint was detection of residual tumor at reTUR, proved with positive pathology report. Results: A total of 109 consecutive patients with high-risk NMIBC underwent reTUR after a primary complete blue light resection. Pathologic evaluation of the surgical specimens of the primary TURBT revealed stage T1 and high-grade tumors in 69 (68.3%) and 108 (99%) patients, respectively, and concomitant carcinoma in situ was found in 45 patients (41.3%). The median time to reTUR was 8 (6-10) weeks. Residual tumor was detected histopathologically in 64 of 109 patients (58.7%) at the second TURBT with PDD. In five of these patients (4.5%), initial T1 tumors were upstaged to T2 tumors. Conclusions: We examined a contemporary series of patients undergoing reTUR with PDD as management of high-risk NMIBC proven at the first blue light resection. We reported a 54.2% risk of disease persistence and a 4.5% risk of understaging in T1 tumors. These findings support that reTUR is still necessary after initial complete TURBT with PDD. Further studies are needed to assess the long-term oncologic outcomes of reTUR with PDD.

Purpose: To evaluate the efficacy and safety of benign prostatic obstruction (BPO) surgery in patients with preoperative urinary catheterization. Patients and Methods: We conducted a multi-institutional retrospective study including all patients who failed a trial without catheter (TWOC) after acute urinary retention (AUR) between January 2017 and January 2019. Patients with neurogenic bladder, prostate cancer, or urethral stricture were excluded from the analysis. Patients underwent either monopolar/bipolar transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), prostate artery embolization (PAE), open prostatectomy (OP), or endoscopic enucleation. The primary endpoint was 12-month urinary catheter-free survival without using benign prostatic hyperplasia medications. Results: One hundred seventy-one consecutive men (median age: 71 years; median prostate volume: 75 cm3) underwent BPO surgery, including 48 (28%) TURP, 62 (36.3%) PVP, 21 (12.3%) endoscopic enucleation, 15 (8.8%) PAE, and 25 (14.6%) OP. The median duration of preoperative urinary catheterization was 69 days (interquartile range 46-125). The 12-month urinary catheter-free survival rate was 84.8% (145/171). Satisfactory voiding returned to 121 patients (70.8%). On backward stepwise multivariable analysis, PVP (odds ratio [OR] 0.27 [0.10-0.69]; p = 0.008), PAE (OR 5.27 [1.28-27.75]; p = 0.03), endoscopic enucleation (OR 0.08 [0-0.49]; p = 0.023), OP (OR 0.10 [0.01-0.57]; p = 0.034), Charlson score (OR 1.36 [1.14-1.66]; p = 0.001), and number of preoperative TWOC failure (OR 2.53 [1.23-5.51]; p = 0.014) were significantly associated with catheter-free survival. Conclusions: In this multi-institutional retrospective study, including patients with preoperative catheterization, the overall success rate of BPO surgery was 70.8% after 1-year follow-up. Compared with TURP, enucleation methods and PVP were associated with better catheter-free survival, whereas PAE was associated with higher risk of AUR recurrence.

PURPOSE: To evaluate the prognostic value of procalcitonin (PCT) in the occurrence of infectious complications in the management of acute obstructive pyelonephritis (AOP) compared with other biological parameters (leucocyte count, C-reactive protein [CRP]). METHODS: We conducted a retrospective study including patients who were treated for AOP and performed serum PCT tests in our center between January 1, 2017 and December 31, 2017. Upper urinary tract obstruction was confirmed by either ultrasound or CT urography. Clinical examinations and laboratory tests including leukocyte count, CRP, urine and blood cultures, and serum PCT measurements were performed in the emergency unit. Treatment included early renal decompression using indwelling ureteral stents or nephrostomy and empiric antibiotic therapy. The primary endpoint was occurrence of severe sepsis (SS), a composite criterion including urosepsis and/or septic shock and/or admission to the intensive care unit (ICU) and/or death. RESULTS: A total of 110 patients (median age: 61 years) were included, of whom 56.3% were female. SS occurred in 39 cases (35.4%). Multivariate regression analysis showed that serum PCT (OR 1.08; 95% CI 1.03-1.17; p = 0.01), CRP (OR 1.007; 95% CI 1.001-1.015; p = 0.03), and diabetes mellitus (OR 5.1; 95% CI 1.27-27.24; p = 0.04) were independent predictors for SS. Serum PCT was the biological marker associated with the highest accuracy to predict SS (ROC 0.912 (95% CI 0.861-0.962) and was superior to CRP (p < 0.001): the sensitivity and specificity of PCT to predict SS were 95% and 77%, respectively, with a serum PCT cutoff value of 1.12 µg/L. CONCLUSIONS: PCT levels > 1.12 µg/L could help physicians to identify high-risk patients who could benefit from early and aggressive management in collaboration with intensive care specialists.

OBJECTIVE: To report the effectiveness, reliability and learning curve of Microperc, a minimal invasive percutaneous technique using a 4.85-Ch (16-gauge) sheath, in the treatment of nephrolithiasis. MATERIAL AND METHODS: 31 consecutive Micropercs for nephrolithiasis<2.5cm were performed by 2 operators in 2 different institutions from the 1st of May 2015 to 31st of December 2017. RESULTS: The mean size of stones was 19mm±11mm, and mean density was 1048±249UH. Stones were located in lower calyx in 21/31(68%), medium calyx in 3/31(10%), pelvis in 4/31(12%) and were multi-caliceal in 3/31(10%). Five patients (16%) had urinary diversion (4 ileal conduits, 1 enterocystoplasty with Mitrofanoff+bladder neck closure) all of those having neurological disease (2 multiple sclerosis, 3 spinal cord injury). Mean operating time was 83±35min and decreased after short period for both operators. 9/31(29%) patients had complication: 8 (26%) had fever (Clavien II) and 1 (3%) had renal colic pain (Clavien III) (required JJ stent). Stone-free was obtained in 13/31(42%) and 11/31(36%) had residual microfragments<3mm which did not require further treatment, corresponding to a technical success of 78% (24/31). Success rate was similar in patients with urinary diversion and patients with normal anatomy. CONCLUSIONS: This study showed that Microperc was an effective technic for kidney stone treatment with low complication rate, acceptable operating time and short learning curve. Microperc was useful for stones in the lower calyx and/or urinary diversion where retrograde ureteroscopy could reach its limits. LEVEL OF EVIDENCE: 3.

OBJECTIVE: To report the efficacy and safety of povidone-iodine sclerotherapy of primary symptomatic lymphocele after kidney transplantation in a large contemporary cohort study. PATIENTS AND METHODS: A single-institutional study was conducted including consecutive patients who underwent povidone-iodine sclerotherapy for primary symptomatic lymphocele after kidney transplantation between January 2013 and March 2020. Sclerotherapy was used as the first-line treatment of symptomatic lymphocele. Recurrent lymphoceles were managed with open or laparoscopic fenestration. The primary outcome was the efficacy of sclerotherapy which was defined as the absence of second sclerotherapy or salvage surgery. RESULTS: A total of 965 renal transplantations were included. Sclerotherapy for primary symptomatic lymphocele was performed in 60 cases (6.2%). The median (IQR) number of instillation, the volume of povidone-iodine per instillation and drainage time were 3 (3-3), 60 (38-80) mL and 6 days (5-8), respectively. Sclerotherapy related complications were reported in eight cases (13.3%) and included five cases of accidental catheter removal, two cases of lumbosciatica, and one case of intraperitoneal diffusion of povidone-iodine. After a median (IQR) follow-up of 33 (14-60) months, treatment success was achieved in 33 cases (55%). Multivariate analysis failed to identify predictors of sclerotherapy failure. Salvage therapies included 7 s sclerotherapy and 20 surgical fenestrations with an overall success rate of 88.8% (24/27). CONCLUSIONS: Sclerotherapy was an easy and safe procedure to treat primary symptomatic lymphocele in renal transplant recipients. Despite moderate efficacy, recurrences were easily controlled with salvage therapies. Further studies are necessary to identify predictive factors of sclerotherapy failure to directly refer patients to surgical treatment.

PURPOSE: To evaluate the negative predictive value (NPV) of multiparametric magnetic resonance imaging (mpMRI), alone or combined with Prostate-Specific Antigen density (PSAd) to exclude clinically significant prostate cancer (csPCa). PATIENTS AND METHODS: We performed a retrospective chart review of all the patients who had transrectal ultrasound-guided biopsy (TRUSGB) in our center between January 2014 and March 2019. We included patients who had nonsuspicious prebiopsy mpMRI defined as Prostate Imaging-Reporting and Data System (PI-RADS) ≤ 2. MRI was performed using a 1.5 or 3-Tesla Magnetic Resonance scanners with external phased-array coil. The primary outcome was the detection of csPCa, defined as a Gleason score 3 + 4 (ISUP 2) or higher on at least one biopsy core. RESULTS: One hundred and ninety-one consecutive men (median age: 65 years, median PSA level: 9.3 ng/mL) underwent TRUSGB following negative prebiopsy mpMRI corresponding to 126 (66%) biopsy-naïve patients, 36 (18.8%) patients with prior negative biopsy, and 29 (15.2%) patients under active surveillance with confirmatory biopsies. The overall PCa and csPCA detection rates were 26.7% and 5.2%, conferring a NPV of 73.3% and 94.8%, respectively. The NPV of negative mpMRI improved to 95.8% in patients with PSAd < 0.15 ng/mL/cm3 and to 100% in patients with PSAd < 0.10 ng/mL/cm3. CONCLUSIONS: A negative prebiopsy mpMRI had an overall NPV of 94.8% for csPCa when mpMRI was used alone to 95.8% when combined with PSAd < 0.15 ng/mL/cm3. Future studies are needed to balance the low benefit of a biopsy in this indication with the morbidity of the procedure.

OBJECTIVE: To evaluate the renal function outcomes after selective trans-arterial embolization (SAE) of iatrogenic vascular lesions (IVL), including pseudoaneurysm and arteriovenous fistula, following partial nephrectomy (PN). MATERIALS AND METHODS: A multi-institutional study was conducted including consecutive patients who underwent PN between January 2009 and March 2019. Two surgical approaches were used: open and robot-assisted PN. Patients with SAE were identified and matched (1:2) with patients without IVL. The matching criteria were age, gender, Charlson score, creatinine clearance, RENAL score, and tumor size. The primary outcome was the evolution of global renal function at 6-months postoperatively. RESULTS: A total of 493 consecutive PN (360 open PN and 133 robot-assisted PN) were included. IVL occurred in 17 cases (3.4%) without statistical difference according to the surgical approach (P = .78). Patients from embolization group were matched to 34 cases without postoperative IVL. Groups were comparable concerning clinical, tumor and surgical characteristics. The clinical success of SAE, defined as the absence of recourse to a second embolization or a total nephrectomy, was obtained in 16 (94.1%) cases. No minor or major complications were reported after SAE. The preoperative estimated glomerular filtration rate (eGFR) was similar between control group (93 [85-102] ml/min) and embolization group (95 [83-102] ml/min) (P = .99). Median (IQR) eGFR between control group (87 [72-95] ml/min) and embolization group (83 [76-93] ml/min) at a follow-up of 6 months showed no significant difference (P = .73). CONCLUSION: IVL are rare complications of PN. SAE is an effective and minimally invasive management tool, with no deleterious effect on global renal function.

PURPOSE: In our center, until 2018, MRI-targeted biopsy was underused. Since January 2018, we systematically performed MRI-targeted biopsy for suspicious PI-RADS ≥ 3 lesions in accordance to the recent guidelines. We hypothesized that the implementation of systematic prebiopsy MRI would increase the detection rate (DR) of prostate cancer (PCa) without increasing DR of clinically insignificant PCa (insignPCa). PATIENTS AND METHODS: A retrospective study including consecutive men who underwent prostate biopsy for suspicion of PCa in our center between January 2017 and December 2018 was conducted. Combined biopsies were performed for suspicious MRI and systematic biopsies for nonsuspicious MRI. The primary outcome was to compare the DR of PCa per year. Secondary outcomes included DRs of clinically significant PCa (csPCa) and insignPCa between both years and outcomes of targeted vs systematic biopsies. RESULTS: A total of 306 men (152 in 2017 and 154 in 2018) were included. Respectively, median (IQR) age was 69 (63-75) vs 70 (65-76) years (p = 0.29) and median (IQR) PSA density was 0.17 (0.13-0.28) vs 0.17 (0.11-0.26) (p = 0.24). There was a significant increase in prebiopsy MRI performed (120 [78.9%] vs 143 [92.8%]; p < 0.001) in 2018. DRs of PCa (94 [61.8%] vs 112 [72.7%]; p = 0.04) and csPCa (76 [50%] vs 95 [61.6%]; p = 0.04) increased in 2018, while the insignPCa DR was stable (p = 0.13). The DR of PCa was 58.3%, 65% and 71.2%, respectively, in targeted, systematic and combined biopsies (p = 0.02). In case of nonsuspicious MRI, the prevalence of csPCA was 12.5%. CONCLUSIONS: Introducing systematical MRI-targeted biopsy in our clinical setting increased the PCa DR without overdiagnosing insignPCa. Implementation of prebiopsy MRI does not seem to avoid the need for systematic biopsy, and nonsuspicious MRI should not obviate the need for prostate biopsy when otherwise clinically indicated.

PURPOSE: Urinary tract infection (UTI) is a common complication after flexible ureteroscopy (fURS) despite technical precautions to avoid infectious complications. The aim was to investigate incidence and predictive risk factors of UTI following fURS procedure. PATIENTS AND METHODS: We conducted a retrospective study including consecutive fURS performed in our center from January 2015 to March 2019. The indications were: nephrolithiasis management and diagnosis and conservative treatment of upper urinary tract urothelial carcinomas (UTUC). Since 2015, we had technical precautions to avoid postoperative infectious complications: centralized collection of preoperative urine cultures which are examined daily by an urologist and a service provider, systematic use of ureteral access sheath and application of standardized antibiotic prophylaxis measures. The primary endpoint was occurrence of UTI within 15 days following fURS. RESULTS: Six hundred and four fURS were included for nephrolithiasis (n = 462) and UTUC management (n = 142). The median (IQR) age in the study cohort was 61(48-68) years, 268 female patients were included (44.4%), the median (IQR) Charlson score was 2(1-4) and single-use fURS were used in 186 cases (30.8%). Postoperative UTI occurred in 41 cases (6.7%). In multivariate analysis, female gender (OR 2.20 [1.02-5.02], p = 0.04), UTI within the last 6 months (OR 2.34 [1.12-5.11], p = 0.02), preoperative polymicrobial urine culture (OR 4.53 [1.99-10.56], p < 0.001) and increased operative time (OR 1.02 [1.002-1.031], p = 0.02) remain associated with postoperative UTI. CONCLUSIONS: In a large cohort study, female gender, prior UTI, increased operative time and preoperative polymicrobial urine culture were associated with the occurrence of postoperative UTI. Limiting operative time and improving our knowledge of polymicrobial urine cultures could reduce the infectious risk.

PURPOSE: There have recent reports in the literature of increased rates of bladder recurrence (BR) after radical nephroureterectomy (RNU) when diagnostic flexible ureteroscopy (DFU) was performed before RNU. The technical heterogeneity of DFU was a major bias in these studies. Our purpose was to evaluate the impact of a standardized DFU technique before RNU on the risk of BR. METHODS: A retrospective monocenter study including patients who underwent RNU for upper tract urothelial carcinoma (UTUC) between 2005 and 2017. 171 patients were identified. 78 patients were excluded owing to a history of bladder cancer before RNU or neo-adjuvant/adjuvant chemotherapy. 93 included patients were stratified according to pre-RNU ureteroscopy (DFU + 70 patients) or no pre-RNU ureteroscopy (DFU-23 patients). The standardized DFU technique consisted of systematic ureteral sheath (ch9-10), flexible ureteroscopy, biopsy, and drainage with a mono-J/bladder catheter to avoid contact of contaminated urine of the upper tract with the bladder. RESULTS: Epidemiological, initial staging, and postoperative tumoral characteristics were similar in both groups. Mean follow-up was 35 months [2-166], 47(50%) BR occurred with 41(87%) in the DFU + group, and pre-RNU-DFU was an independent predictive factor of BR (OR = 4[1.4-11.9], P = 0.01) (Cox regression model). The characteristics of BR were similar in both groups, although BR occurred earlier in DFU + (427 days vs. 226 days (P = 0.07)). CONCLUSION: Bladder recurrence after diagnostic ureteroscopy + nephroureterectomy was high despite technical precautions to avoid contact of bladder mucosa with contaminated urine from the upper urinary tract. Post-DFU endovesical instillation should be investigated.

OBJECTIVES: To describe a new technique for robot-assisted AMS-800 artificial urinary sphincter (AUS) bladder neck implantation in women. PATIENTS AND METHODS: We reviewed the medical files of patients who underwent robot-assisted AUS implantation between March 2017 and November 2018 at our centre. All of the implantations were performed using a posterior approach to the bladder neck in order to avoid blind dissection and the risk of vaginal and/or bladder injury. This strategy was viewed as an alternative to the anterior robot-assisted implantation recently described. The AUSs were activated 5 weeks after implantation. Patients were followed up at 3, 6 and 12 months, then annually. RESULTS: Eight patients, with a median age of 64 years, underwent robot-assisted AUS implantation via a posterior approach to the bladder neck. The median preoperative pad weight was 300 g/24 h. The median operating time was 244 min. No peri-operative vaginal and or bladder injuries were observed. At a median of 12 months of follow-up, all the AUSs were functional. Five patients required no protection (62.5%), three had day protection (37.5%), and all said they were satisfied except for one patient (12.5%) who requested treatment for persistent urge incontinence. CONCLUSION: Robot-assisted AUS implantation in women via a posterior approach to the bladder neck is a procedure that is simple, reproducible and safe. The short-term functional results are satisfactory and comparable to those obtained via an open approach. A more long-term comparison of the efficacy and longevity of AUSs implanted using this posterior approach is needed to confirm its benefit compared with the anterior robot-assisted approach and the classic open technique.

PURPOSE: Reusable flexible-ureteroscopes (fURS) require personnel and budget for processing and repairing, whereas single-use fURS were recently developed. After exclusive reusable fURS since 2011, we experienced high repair costs and single-use fURS were therefore introduced in mid-2017. We aimed to evaluate economic and practical advantages and disadvantages of reusable versus single-use fURS. MATERIALS AND METHODS: First, we evaluated the incidence of breakage and repairs of reusable fURS in 2017. We assessed the overall operational costs of reusable fURS including purchase, processing, and repairing in our institution from 2011 to 2017. Following our experience, we created a model to compare operation costs/procedure of single-use fURS with reusable fURS depending on repair costs. RESULTS: In 2017, repair costs of reusable fURS increased by 345% compared with the period 2011-2016, causing: a median unavailability per reusable fURS of 200 days/year (100-249), median number of functioning fURS 0/5-3/5 per operating day, while unavailability of reusable fURS had become the first reason for cancellation of procedure. Since it was introduced, single-use fURS accounted for 59% of the flexible ureteroscopy activity. Taking into account the costs of processing, maintenance and repair, in 2011-2016 versus 2017, the single-use fURS was cost-effective compared with the reusable fURS until the 22nd procedure versus the 73rd procedure, respectively. CONCLUSIONS: After years of exclusive reusable fURS, the rising incidence of breakage not only increased maintenance costs but also hampered daily activity owing to unavailability of the devices. The introduction of single-use with reusable fURS provided substantial help to maintain our activity.

OBJECTIVE: To evaluate the clinical efficacy, urodynamic effect and safety of Botulinum Toxin A (BTXA) injections after failure of augmentation enterocystoplasty (AE) performed for neurogenic detrusor overactivity. PATIENTS AND METHODS: We performed a multicenter retrospective study that included patients who had AE and at least one injection of BTXA after AE in 15 GENULF (French Speaking Neuro-Urology Study Group) centers. Clinical and urodynamic data were collected from medical files according to a standardized questionnaire and colligated in an anonymous database. RESULTS: Thirty-three patients with an injection of BTXA after AC in 9 out of 15 centers were included. Mean age at the time of AE was 24 ± 15 years. Overall efficacy (defined by clinical efficacy associated with a request by the patient for reinjection) was observed in 58% of the patients. Mean maximum cystomanometric capacity increased by 28% (333 ± 145 vs 426 ± 131 mL; Pâ¯=â¯.007) and maximum detrusor pressure (Pdet max) decreased by 43% (44 ± 37 vs 25 ± 18 cm H2O; Pâ¯=â¯.02) after BTXA. Only one side effect was recorded out of the 152 procedures (transient generalized muscle weakness without respiratory distress). CONCLUSION: In patients with failure after AE performed for neurogenic detrusor overactivity, injection of BTXA in the enlarged bladder was effective in over half of the cases with low morbidity. If this therapeutic approach were confirmed, it could be proposed as an alternative to AE surgical revision.

AIMS: To assess the outcomes of switching to a different brand of botulinum toxin A (BTA, from Botox® to Dysport®) in case of failure of intradetrusor injections (IDI) of Botox® in the treatment of neurogenic detrusor overactivity (NDO). METHODS: The charts of all patients who underwent a switch to IDI of Dysport® after failure of an IDI of Botox® at six departments of neurourology were retrospectively reviewed. The main outcomes of interest were the bladder diary data and four urodynamic parameters: maximum cystometric capacity (MCC), maximum detrusor pressure (PDET max), and volume at first uninhibited detrusor contraction (UDC). RESULTS: Fifty-seven patients were included. After the first injection of Dysport®, no adverse events were reported. A significant decrease in number of urinary incontinence episodes per day was observed in 52.63% of patients (P < 0.001) and all patients experienced a reduction in PDET Max (-8.1 cmH20 on average; P = 0.003). MCC significantly increased by a mean of 41.2 (P = 0.02). The proportion of patients with no UDC increased significantly at week 6 after ATA injections (from 15.79% to 43.9%; P = 0.0002). Hence, 32 patients draw clinical and/or urodynamic benefits from the botulinum toxin switch from (56.14%). After a median follow up of 21 months, 87% of responders to BTA switch were still treated successfully with BTA. CONCLUSION: Most patients refractory to Botox® (56.14%) draw benefits from the switch to Dysport®.

PURPOSE: We evaluated the success of endoscopic treatment of symptomatic vesicoureteral reflux after renal transplantation and identified factors predicting success. MATERIALS AND METHODS: Endoscopy was performed for symptomatic vesicoureteral reflux after renal transplantation in 38 women and 20 men between January 2000 and December 2010. Reflux was documented by retrograde cystography and its symptomatic character was determined by at least 1 episode of acute graft pyelonephritis. The results of endoscopic treatment were evaluated clinically at 1 and 3 months, and annually, and by cystography at 3 months. Clinical success was defined as absent acute graft pyelonephritis during followup. Radiological success was defined as absent reflux on followup cystography at 3 months. RESULTS: Endoscopic treatment was clinically successful in 32 patients (56.1%), including 26 (65%) who received dextranomer-hyaluronic acid and 5 (33.3%) who received polydimethylsiloxane. Treatment was radiologically successful in 14 patients (26.4%) at a mean ± SD followup of 38 ± 33 months. On multivariate analysis male gender and dextranomer-hyaluronic acid were factors predictive of clinical success. Reflux grade did not predict success or failure. No high grade complication was reported. CONCLUSIONS: Endoscopic treatment of symptomatic vesicoureteral reflux of a transplanted kidney was effective in half of the cases regardless of the bulking agent used. However, dextranomer-hyaluronic acid appeared to be more effective than polydimethylsiloxane. Due to its minimally invasive nature and low morbidity endoscopic treatment with dextranomer-hyaluronic acid could be proposed as preoperative first line treatment for symptomatic vesicoureteral reflux of a transplanted kidney regardless of reflux grade.
