Background: To assess if trans-urethral snare of bladder tumor (TUSnBT) with subsequent stone basket retrieval can be used as an effective, time-saving adjunct resection technique for papillary bladder lesions. Methods: Via standard cystoscopy, TUSnBT was performed using a standard endoscopic polypectomy snare with subsequent tumor extraction utilizing a standard stone retrieval basket, when lesions were more than 10 mm in diameter. Smaller lesions were removed with the polypectomy snare. Standard trans-urethral resection of bladder tumors (TURBT) of the tumor bed was performed post TUSnBT. Histological assessment was performed and assessed separately per session. Results: In total, 18 papillary lesions, measuring between 9 and 26 mm, were resected via TUSnBT. Operative TUSnBT time, ranged between 10 and 60 seconds duration per lesion. No significant postoperative morbidity was experienced by patients within this cohort. Histo-pathological assessment revealed adequate muscle representation in 83.3 % of TUSnBT grouped sessions assessed. Conclusion: TUSnBT with stone retrieval basket retrieval is a feasible method in selected papillary bladder lesions, and may be coupled with standard TURBT resection techniques. This method is less time consuming and would prove beneficial in select lesions. It may also be beneficial to assist with reducing the resection time or inadvertent bladder perforation encountered during the conventional TURBT.

Transurethral resection of bladder tumor (TURBT) is the standard of care for initial bladder tumor management. In response to its shortcomings, we propose an alternative technique for tumor resection and retrieval: The endoscopic snare resection of bladder tumor (ESRBT). Eleven tumors managed by ESRBT were reviewed retrospectively. Via cystoscopy, tumors were resected en bloc with an electrosurgical polypectomy snare and retrieved transurethrally. Safety and efficacy were assessed by clinical and pathologic outcomes. ESRBT was highly effective for appropriate tumors. Tumor size and location varied: Two small, six medium, three large; six lateral wall, two dome, two trigone, one posterior wall. Half of initial urothelial carcinoma specimens contained muscle. There were no intraoperative or postoperative complications (mean follow-up: 17 mos; range 10-25 mos). ESRBT is a feasible technique for the resection of pedunculated bladder tumors. It offers evident and theoretical advantages over TURBT and may augment bladder tumor management. Further study is needed.
