Background: The surgical treatment of bladder tumors is now safer thanks to recent developments in transurethral instrumentation for the treatment of bladder tumors. Specifically, the use of bipolar energy has improved the incidence of both short-term and long-term bleeding and produced long-lasting therapy benefits. Objective: To compare bipolar versus monopolar transurethral resection of bladder tumors (B-TURBT vs M- TURBT) in terms of its clinical and pathological outcome. Methods: A cross-sectional retrospective study was conducted on 200 patients that fit the inclusion criteria who were enrolled in the study and randomized for bipolar TURBT (B-TURBT) and (M-TURBT) during the period from May 2022 to January 2024 at Damanhur National Medical Institute. A thorough history and clinical examination and laboratory investigations were recorded preoperatively, intraoperatively, and postoperatively as well as the pathological analysis. Results: There was a significant difference among the studied group regarding resection time, hemoglobin drop, hospital stay, catheter time (p < 0.05). There wasn't significant difference among the studied group regardingserum(S.) Na drop (p>0.05). There wasn't significant difference among the studied group regarding number of lesions, second look TURBT (p>0.05). There was a significant difference among the studied group regarding tissue artifact (p < 0.05).  Most (51%) of the Bipolar group was at Ta stage and 46% of Monopolar group was at Ta stage, (62%) most of the Bipolar group was low grade and 57% of Monopolar group was low grade, and there wasn't significant difference among the studied group regarding stage and grade (p>0.05). Conclusion: Bipolar TURBT is safe and effective in treating bladder tumors. It is advantageous in decreased resection time, hemoglobin drop, catheterization time, hospital stay and tissue artifact.
