RESUMO
OBJECTIVES: To determine the safety and oncological advantages of en bloc resection of bladder tumour (ERBT) vs conventional transurethral resection of bladder tumour (cTURBT) in terms of resection quality, staging quality, and safety. PATIENTS AND METHODS: We conducted a single-blinded randomised controlled trial at seven European hospitals with the following inclusion criteria: first diagnosis of non-muscle-invasive bladder cancer, no singular carcinoma in situ, and tumour size >4.3 mm. Patients were randomised intraoperatively in a 1:1 ratio to either the ERBT or cTURBT group. Outcome analysis was performed using the chi-square test, t-test, and multivariate regression analysis. RESULTS: A total of 97 patients were randomised into the study (cTURBT = 40, ERBT = 57). A switch to cTURBT was necessary in two patients (3.5%) and 11.5% of the screened patients were preoperatively excluded for ERBT. There was no difference in the specimen presence of detrusor muscle with 73.7% in cTURBT and 67.3% in ERBT specimens (P = 0.69). There were no significant differences in mean operative time (ERBT 27.6 vs cTURBT 25.4 min, P = 0.450) or mean resection time (ERBT 16.3 vs cTURBT 15.5 min, P = 0.732). Overall the complication rate did not differ significantly (ERBT 18.2% vs cTURBT 7.5%, P = 0.142). Bladder perforations occurred significantly more often in the ERBT group (ERBT seven vs cTURBT none, P = 0.020). R0 status was reported more often after ERBT, whilst a second resection was significantly less frequent after ERBT (P = 0.018). Recurrence rates were comparable for both techniques after 6 months of follow-up. CONCLUSION: The feasibility of ERBT is higher than previously reported. Whereas other perioperative and safety parameters are comparable to cTURBT, bladder perforations occurred significantly more often in the ERBT group and raised safety concerns. This is why this trial was terminated.
RESUMO
INTRODUCTION: Guideline recommendations are meant to help minimize morbidity and to improve the care of nonmuscle invasive bladder cancer (NMIBC) patients but studies have suggested an underuse of guideline-recommended care. The aim of this study was to evaluate the level of adherence of German and Austrian urologists to German guideline recommendations. METHODS: A survey of 27 items evaluating diagnostic and therapeutic recommendations (15 cases of strong consensus and 6 cases of consensus) for NMIBC was administered among 14 urologic training courses. Survey construction and realization followed the checklist for reporting results of internet e-surveys and was approved by an internal review board. RESULTS: Between January 2018 and June 2019, a total of 307 urologists responded to the questionnaire, with a mean response rate of 71%. The data showed a weak role of urine cytology (54%) for initial diagnostics although it is strongly recommended by the guideline. The most frequently used supporting diagnostic tool during transurethral resection of the bladder was hexaminolevulinate (95%). Contrary to the guideline recommendation, 38% of the participants performed a second resection in the case of pTa low-grade NMIBC. Correct monitoring of Bacille Calmette-Guérin (BCG) response with cystoscopy and cytology was performed by only 34% of the urologists. CONCLUSIONS: We found a discrepancy between certain guideline recommendations and daily routine practice concerning the use of urine cytology for initial diagnostics, instillation therapy with a low monitoring rate of BCG response, and follow-up care with unnecessary second resection after pTa low-grade NMIBC in particular. Our survey showed a moderate overall adherence rate of 73%. These results demonstrate the need for sharpening awareness of German guideline recommendations by promoting more intense education of urologists to optimize NMIBC care thus decreasing morbidity and mortality rates.

BACKGROUND: Surgical educational videos represent a contemporary, multimedia supplement to surgical education and training. The German Society of Residents in Urology e.â¯V. (GeSRU) developed an educational video platform (steps.GeSRU.de) with free, quality-assured educational videos for urologists, especially for residents. OBJECTIVES: The purpose of this study was to evaluate the GeSRU Steps teaching videos. MATERIALS AND METHODS: Prospectively, 29 GeSRU Steps training videos were made available (03/2019-05/2023) via amboss.com, and an online questionnaire was inserted following the videos. This comprised 12 items on medical, technical, and didactic quality, usefulness for own knowledge acquisition, and sociodemographic data of respondents. Aspects of video quality were assessed with the Acceptability Escale and the Global Quality Score. RESULTS: During the survey period, the GeSRU Steps videos implemented on the amboss.com website were viewed 49,698 times. A total of 474 questionnaires were answered (rate 0.25%). The collective of respondents consisted of 419 (88%) students, 47 (10%) physicians in training, and 5 (1%) specialists; 351 (74%) were female, 107 (23%) were male, and 4 (1%) were diverse. Each educational video was rated a median of 10 times (range 5-65). The six questions of the Acceptability Escale and the Global Quality Score were rated good and very good (81.6-95.8%), respectively. CONCLUSIONS: GeSRU teaching videos achieved a very good rating with high user satisfaction. By specific promotion of these teaching videos, which are quality-assured through supervision, the portfolio of surgical videos available at a low threshold can be expanded and can serve as a contemporary education tool.
