Background: Level 1 evidence supports the administration of single postoperative intravesical chemotherapy (pIVC) following radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC), in order to decrease intravesical recurrence risk. Objective: The Young Academic Urologist Urothelial Cancer Group aimed to investigate the use of pIVC in daily practice among European colleagues. Design, setting, and participants: An online survey was shared with European Association of Urology Section of Oncological Urology (ESOU) 2017 participants via e-mail. Submissions were accepted from April to June 2017. The topics for 15 questions of this survey included the habit of delivering pIVC, the choice of drug, its dosage, related doubts or concerns, reasons not to perform pIVC, knowledge of the evidence, and surgical preferences for RNU. Outcome measurements and statistical analysis: Survey software was used for analyses. Logistic regression analyses were used to investigate the association between surgeons’ experience and caseloads with pIVC utilization. Results and limitations: Overall, 127 responses were collected (11.6%). About half of the participants (47%) regularly administered pIVC following RNU. The drug most commonly utilized was mitomycin (85%); 82% adhered to the standard dosage of 40 mg. Different administration protocols were adopted: ≤48 h (39%), 7–10 postoperative days (35%), >10 d (11%), and intraoperatively (10%). The evidence was supported by prospective randomized clinical trials for only 65% of responders. Among interviewees who did not deliver pIVC, the most commonly reported reasons were lack of supporting data (55%), fear of potential side effects (18%), and organizational hurdles (15%). Conclusions: Our research highlights the limited use of pIVC following RNU for UTUC, raising the question of how the compliance with level 1 evidence in the urological community may be promoted. Patient summary: Level 1 evidence supports the administration of single postoperative intravesical chemotherapy (pIVC) following radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC), in order to decrease intravesical recurrence risk.
