[Current state of knowledge of urology residents and fellows on the neuro-urological management of spina bifida patients in France]. / État des lieux des connaissances des internes et chefs de clinique d'urologie sur la prise en charge neuro-urologique des patients spina bifida en France.

OBJECTIVE: To assess the current knowledge of French urology residents and fellows about neurogenic lower urinary tract dysfunction and their management in patients with spina bifida. MATERIAL AND METHOD: A 7-question questionnaire, covering the responder's experience and the various stages in the neuro-urological management of spina bifida, was drafted by an expert urologist. Responses were collected within 5days of being e-mailed to members of the Association française des urologues en formation (AFUF), and a descriptive analysis was carried out. RESULTS: Of the 448 members, 155 completed the questionnaire. Of the participants, 83.8% said they knew the definition of spina bifida, and 76.8% had already had to care for a spina bifida patient. Of the participants, 48.4% correctly estimated the number of spina bifida patients in France. Neurogenic lower urinary tract dysfunction to look for and the specificities of management seemed to have been acquired by a majority of respondents (correct response rates of 70.7% and 75.4%, respectively), unlike the extra-urological aspects (53.9%), and the choice of examinations useful for the initial work-up and follow-up (55.8%). CONCLUSION: While the expected neurogenic lower urinary tract dysfunction and the specificities of therapeutic management of spina bifida patients appear to be well known to urologists in training, knowledge of extra-urological symptoms and the choice of examinations could be improved. These results could be used to adjust the teaching given to French urologists in training on the urological management of spina bifida patients. LEVEL OF EVIDENCE: Grade 4.

Long-term Recurrence Rates of Low-risk Non-muscle-invasive Bladder Cancer-How Long Is Cystoscopic Surveillance Necessary?

BACKGROUND: While low-risk non-muscle-invasive bladder cancer (LR-NMIBC) has a low propensity to progress, the risk of recurrence remains high (50% within 4 yr). Guidelines recommend cystoscopic surveillance after resection, but the necessary duration of follow-up is debated. OBJECTIVE: To determine the risk of recurrence beyond 5 yr after diagnosis in patients with LR-NMIBC, and to identify risk factors of recurrence. DESIGN, SETTING, AND PARTICIPANTS: In this multicenter retrospective observational study, patients who received their first transurethral bladder tumor resection before 2016 for LR-NMIBC were included. Low risk was defined as a primary, solitary, low grade, Ta bladder tumor measuring <3 cm. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was determination of the recurrence rates at 1, 2, and 5 yr. The secondary endpoints included overall recurrence-free survival (RFS) and high-risk RFS. A univariate analysis and multivariable logistic regression were performed to assess the risk factors for recurrence over the study period. RESULTS AND LIMITATIONS: The median age of the 577 patients was 70.9 yr, and 126 (21.8%) patients were female. The median follow-up was 69.6 (interquartile range: 58.4) mo, and recurrence was observed in 236 (40.9%) patients. The 1-, 2-, and 5-yr RFS rates were 81.6% (95% confidence interval 78.4-84.9), 72.4% (68.7-76.3), and 59.2% (55-63.8), respectively. Recurrence after 5 yr was observed in 13.1% (28/213). High-risk recurrence, defined as the first recurrence of a high-grade and/or ≥T1 tumor, occurred in 6.2% (36/579) overall and 2.8% (6/213) after 5 yr. The lack of a single postoperative dose of chemotherapy and tumor size >2 cm were prognostic factors of recurrence. CONCLUSIONS: The risk of recurrence in patients with LR-NMIBC decreases progressively after the 1st year and remains low beyond 5 yr. Discontinuation of endoscopic surveillance after 5 yr in patients with LR-NMIBC can be discussed. Treatment with postoperative chemotherapy and tumor size <2 cm may be relevant variables to identify patients who will benefit from cystoscopic follow-up as short as 12 mo. PATIENT SUMMARY: In this study, we observed that 13% of patients who did not have a recurrence during the first 5 yr following the diagnosis of low-risk non-muscle-invasive bladder cancer will recur after this time point. Discontinuation of cystoscopic surveillance can be discussed after 5 yr in these patients.

Oncological Outcomes of Distal Ureterectomy for High-Risk Urothelial Carcinoma: A Multicenter Study by The French Bladder Cancer Committee.

Upper urinary tract urothelial carcinoma (UTUC) is an uncommon disease and its gold-standard treatment is radical nephroureterectomy (RNU). Distal ureterectomy (DU) might be an alternative for tumors of the distal ureter but its indications remain unclear. Here, we aimed to evaluate the oncological outcomes of DU for UTUC of the pelvic ureter. We performed a multicenter retrospective analysis of patients with UTUC who underwent DU. The primary endpoint was 5-year cancer-specific survival (CSS), followed by overall survival (OS), intravesical recurrence-free (IVR) and homolateral urinary tract recurrence-free (HUR) survivals as secondary endpoints. Univariate and multivariate Cox regressions were performed to assess factors associated with outcomes. 155 patients were included, 91% of which were high-risk. 5-year CSS was 84.4%, OS was 71.9%, IVR-free survival was 43.6% and HUR-free survival was 74.4%. Multifocality, high grade and tumor size were the most significant predictors of survival endpoints. Of note, neither hydronephrosis nor pre-operative diagnostic ureteroscopy/JJ stent were associated with any of the endpoints. Perioperative morbidity was minimal. In conclusion, DU stands as a possible alternative to RNU for UTUC of the pelvic ureter. Close monitoring is mandatory due to the high risk of recurrence in the remaining urinary tract.
