METHODS A single center, randomized, controlled trial was conducted from May 2013 to September 2014. Patients only with tumors in the lateral bladder wall (lateral to ureteric orifice) were eligible for inclusion in the study. Patients who refused consent, those with coagulation disorders and those who had prior resection within two weeks were excluded. Eligible patients were randomized into two groups: Bipolar Group underwent transurethral resection of the bladder tumor with bipolar plasma kinetic energy and Monopolar group underwent conventional monopolar transurethral resection. Intraoperative and postoperative outcomes were recorded including the incidence of bladder perforation, obturator reflex, postoperative bleeding, hemoglobin decrease and resection time. RESULTS A total of 311 transurethral resections were performed during the study period. Of them, 164 patients were eligible for randomization. Eighty-three patients were included in the monopolar resection group versus 81 in the bipolar group. Patients' demographics were similar between both groups. The incidence of bladder perforation was greater in the monopolar group (13.2% vs. 2.4%, p = 0.02). Similarly, obturator reflex occurred more frequently in the monopolar group (26.5% vs. 4.8% p=0.01). Postoperative persistent bleeding and urine retention requiring reoperation occurred in one patient in the monopolar group. No statistically significant differences were observed between both groups with regards to resection time and hemoglobin deficit. CONCLUSIONS Bipolar transurethral resection of bladder tumors is associated with lower incidence of obturator reflex and bladder perforation compared to monopolar resection. These findings support the benefit of bipolar over monopolar resection in management of laterally located bladder tumors. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e384-e385 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Ahmed M.
