Abstract
Background: En bloc resection of bladder tumors (ERBT) has been used as a treatment option to improve pathologic diagnostic accuracy in non-muscle invasive bladder cancer. We report on the feasibility of a novel ERBT technique using an electrosurgical snare with flexible cystoscope: flexible cystoscopic En bloc Snare Resection of Bladder Tumor (f-ESRBT). Methods: We used the electrosurgical snare to resect a superficial bladder tumor after injection of 50% glucose in the submucosa at the tumor base. We collected each resected tumor with a basket catheter and coagulated the resected area with a coagulation electrode. A flexible cystoscope was used for all procedures. Results/Discussion: We performed 10 operations. Mean tumor size was 10.2 ± 7.3 mm and mean surgery time was 13.8 ± 6.8 minutes. All procedures were performed without complications. Results showed f-ESRBT to be simple and minimally invasive and to enable accurate pathologic diagnoses. Conclusion: f-ESRBT is a feasible treatment option for small and non-muscle invasive bladder cancer.
