Objective: We aimed to compare the safety and efficacy of monopolar and bipolar transurethral resection (TUR) of bladder tumors (TURBTs). Material and Methods: A total of 240 patients who underwent TURBT were prospectively included in the study from May 2011 to May 2014. All patients with suspected bladder tumors were eligible for study inclusion. Those who refused consent and those undergoing routine restaging TURBT were excluded from analysis. Patients were divided on the basis of the monopolar arm and the bipolar arm. Study outcomes included the incidence of bladder perforation and obturator jerk, decrease in hemoglobin and sodium levels, rates of re-coagulation and blood transfusion, TUR syndrome, and operation time. Results: The mean age of the patients was 62 ± 13.7 years. The incidence of obturator jerk and bladder perforation was greater in the bipolar arm. However, with a decrease in the hemoglobin and sodium levels, rates of re-coagulation and blood transfusion were greater in the monopolar arm. Statistical analysis did not show significant differences with regard to study outcomes between the groups. There was no case of TUR syndrome in the 2 arms. The residual tumors' rate was similar between the 2 groups. Conclusions: Our results showed that efficacy and safety of the monopolar and bipolar methods seems to be comparable in patients with bladder tumors.

    Air bubbles floating in the bladder dome during transurethral resection of a bladder tumor can interfere with the resection, causing intravesical explosion and increasing the potential risk of tumor cell reimplantation. We describe a simple and effective technique for evacuating air bubbles from...
