stage and grade were not. Obturator nerve reflex and bleeding were observed in 17.2% and 10.3% of patients treated with conventional TURBT, respectively, compared to none in patients treated with Tmfiber-ERBT. Limitations of the current study include its small size, single center, and nonerandomized nature. CONCLUSIONS: Tm-fiber-ERBT seems to be a safe and efficacious diagnostic and therapeutic approach in patients presenting with NMIBC. Tm-fiber-ERBT had less adverse events, was more likely to secure detrusor muscle in the specimen and resulted in better RFS rates than conventional TURBT. Based on these promising data, we have started a prospective randomized clinical trial comparing en bloc TURB with conventional TURB (ClinicalTrials.gov NCT03718754).
