Abstract

Objective: To describe some clinical, paraclinical characteristics and evaluate early outcomes of transurethral en bloc resection of bladder tumor (ERBT) for non-muscle invasive bladder cancer (NMIBC) at 108 Military Central Hospital. Subject and method: A retrospective-prospective descriptive study of 48 NMIBC patients undergoing ERBT from December 2024 to March 2026. Result: Mean age 64.2 ± 13.9 years (27-86), male-to-female ratio 2.7:1. Gross hematuria was the most common presentation (45.8%). On MRI, VI-RADS ≥ 3 accounted for 57.9%, yet all were confirmed non-muscle invasive on histopathology. Mean operative time was 17.1 ± 3.9 minutes. Intraoperative complications: Obturator nerve reflex 8.3%, extraperitoneal bladder perforation 4.2%, all managed conservatively. Histopathology: 100% urothelial carcinoma, stage T1, high grade 83.3%. The detrusor muscle-containing rate reached 87.5%. Good surgical outcome was 85.4%. Three-month recurrence-free rate was 95.2% (40/42 patients at follow-up). Conclusion: Our initial results suggest ERBT is a feasible technique with short operative time, low complication rate and good specimen quality, representing a valuable option for NMIBC treatment.
