Abstract

Objectives To compare bipolar transurethral resection of bladder tumor (B-TURBT) and monopolar transurethral resection of bladder tumor (M-TURBT) in terms of its perioperative clinical and pathological outcomes. Background Bladder cancer is the seventh most diagnosed cancer in the male population worldwide. TURBT is considered the initial treatment and the only method to provide specimens for tumor staging and grading. Patients and methods This study was conducted at the Urology Department at Menoufia University Hospital during the period of study from April 2018 and April 2020. After consent, newly diagnosed bladder tumor patients who were planned for TURBT at Menoufia University were randomized into two equal groups: B-TURBT and M-TURBT. All patients were evaluated through careful history, physical examination, routine laboratory investigations, ultrasonography, and contrast-enhanced computed tomography. All specimens were examined by a uropathologist who was blinded to the type of energy used. Results There were no statistically significant differences between both groups regarding patients' characteristics, obturator jerk, bladder perforation, completed resection of the tumor, and serum sodium drop. Bipolar resection group showed significantly shorter resection time (P = 0.009), less hemoglobin drop (P = 0.001), less catheterization time (P = 0.044), and less hospitalization time (P = 0.012). Grade 3 tissue artifact on histopathological examination was 16.6 and 23.5% in bipolar and monopolar groups, respectively, with no statistically significant difference. Conclusion Bipolar energy in TURBT is a safe and effective modality as the monopolar one. Bipolar resection is superior to the monopolar one in shortening the resection time, hospital stay and catheterization time and less hemoglobin drop. Both techniques have comparable effects on tissue biopsy, other operative data, and perioperative complications.
