SIU 2017: En-Bloc Transurethral Resection of Non muscle invasive Bladder Cancer: Pathological Effectiveness

Lisbon, Portugal ( En-bloc transurethral resection (en-bloc TUR) is a modified procedure of transurethral resection of the bladder tumor (TURBT) for the patients with non-muscle invasive bladder cancer. The authors of this study investigated cases of en-bloc TUR and the pathological effectiveness in diagnosis.

A total of 78 patients who underwent en-bloc TUR from April 2013 to November 2016 were analyzed. Pathological effectiveness in diagnosis was investigated.

Median size of tumor was 14.3mm (range: 1 to 50mm). Median operation time was 52 min (range: 15 to 157 min). Near perforation occurred in 5 cases, but none of them needed additional treatment and conservative treatment was applied in all patients. No other adverse event had occurred. The muscularis layer was included in the specimen in 66 cases (90.4%). Pathological T stage was as follows: pTa (n=54), pT1 (n=15), >, pT2 (n=2), others (n=7). Recurrence rate and progression rate were 21.2% and 1.1%, respectively. The pathologist could easily diagnose the muscularis mucosa and muscularis propria layers.

According to the authors, en-bloc TUR is a safe and feasible procedure for patients with non-muscle invasive bladder cancer. Pathological T stage could be diagnosed easily by the pathologists, and shortened the time for diagnosis, when compared to standard TUR-BT.
