dc.description.abstractPURPOSE: Traditionally, transurethral resection of bladder tumors (TURB) is performed using monopolar technique. Bipolar resection has been postulated to reduce complications. In this study we compare safety and efficacy between monopolar TURB (mTURB) and bipolar TURB (bTURB) for patients with primary non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: Data were obtained from an international multicenter randomized clinical trial that compared the use of white light cystoscopy with narrow band imaging-assisted TURB using the Olympus system between 2010 and 2014. Main outcomes of interest were operative time, perioperative, and postoperative complications, and 12-month recurrence-free survival. RESULTS: In total, 716 patients were treated for primary NMIBC with mTURB (310 patients) or bTURB (406 patients). The use of white light cystoscopy or narrow band imaging was equally distributed between the 2 resection techniques. Multilevel logistic and linear regression corrected for possible confounders showed no significant difference between mTURB and bTURB for postoperative complications (OR = 1.76, P = 0.180), postoperative bleeding (OR = 1.27, P = 0.722), and the combination of intra + postoperative bleeding (OR = 1.992, P = 0.108). Additionally, no significant difference was found between mTURB and bTURB concerning operative time (1.05min. longer for bTURB, P = 0.536), intraoperative bleeding requiring intervention (OR:1.38, P=0.809), incidence of obturator reflex (OR = 0.93, P = 0.854), and bladder perforation (OR = 3.05, P = 0.195). In total, 185 patients (25.8%) developed a recurrence (mTURB = 88, bTURB = 97). Recurrence-free survival at 12 months in the mTURB and bTURB group was 70% and 74% (P = 0.410), respectively. CONCLUSION: Based on these results, bTURB is as safe and effective as mTURB in treatment of primary NMIBC. bTURB seems to have no evident advantages over mTURB with respect to operation time, perioperative and postoperative complication rates, and recurrence rates at 12 months.-
