Abstract

Purpose: To assess the feasibility of transurethral resection (TUR) of bladder lesions performed entirely by means of a narrowband imaging (NBI) modality. Patients and Methods: Data from an ongoing prospective randomized trial (NCT01004211) were extracted. Quality outcomes of standard TUR and NBI TUR were compared. Complications were graded according to the Clavien-Dindo system. Results: To date, 33 and 29 subjects were randomized to standard and NBI TUR. No significant differences regarding age, sex, American Society of Anesthesiologists score, rate of multiple lesions, or lesions larger than 3? cm in the two groups were found, whereas rate of TUR for recurrent bladder cancer was greater in the NBI group. All procedures ended with complete clearance of the suspected or overt bladder tumor in the modality assigned. No death or major surgical or medical complications were registered. Overall grade I to II complications rate in the NBI and standard groups was, respectively, 8/29 (27%) and 11/33 (33%) (P? =? 0.831). Median surgery time was, respectively, 20 and 30 minutes in the NBI and standard group (P? =? 0.381). Median time to catheter removal was, respectively, 2 and 3 days in the NBI and standard groups (P? =? 0.288). Median time to discharge was 2 and 3 days (P? =? 0.173). No patient was readmitted after discharge. Muscle tissue was absent in the specimen of one patient who underwent standard TUR. Conclusion: NBI TUR appears to be feasible. The results of the ongoing randomized trial will show whether NBI TUR is able to reduce significantly the 1-year recurrence rate of bladder tumors.
