Resumo: ABSTRACT Introduction: The aim of the present prospective-randomized study was to compare perioperative outcomes and complications of bipolar and monopolar TURBT for lateral wall-located non-muscle invasive bladder cancers (NMIBC) under obturator nerve block (ONB). Patients and Methods: 80 patients who underwent TURBT for lateral wall-located primary bladder tumors under ONB from March, 2016 to November, 2019 were included in the present study. The patients were randomized equally into two groups; monopolar TUR (M-TURBT) and bipolar TUR (B-TURBT). The primary and secondary outcomes were safety (obturator jerk and bladder perforation) and efficacy (complete tumor resection and sampling of the deep muscle tissue). Results: Obturator jerk was detected in 2 patients (5%) in M-TURBT while obturator jerk was not observed during B-TURBT (p=0.494). Bladder perforation was not observed in both groups. All of the patients underwent complete tumor resection. There was no significant difference in muscle tissue sampling (67.5% vs. 72.5%, p=0.626) and thermal tissue damage rates (12.5% vs. 25%, p=0.201). The majority of complications were low-grade and the differences in Clavien grade 1-3 complications between groups were not statistically significant. Conclusion: In the treatment of lateral-wall located NMIBCs, either M-TURBT or B-TURBT can be safely and effectively performed by combining spinal anesthesia with ONB. Even so, it should be taken into consideration that low-grade postoperative hemorrhagic complications may occur in patients who undergo M-TURBT.
