Radical cystectomy is the gold standard for muscle-invasive bladder. Orthotopic ileal neobladder, as one of the urinary diversion methods, is preferred whenever possible to achieve a better postoperative quality of life.~For standard radical cystectomy (SRC) in females, the uterus, fallopian tubes, ovaries, anterior vaginal wall, and regional lymph nodes undergo en bloc resection with the bladder and urethra . With regard to the wide range of resection, continence disorder and sexual dysfunction are very common after surgery. Pelvic-organ sparing radical cystectomy involves the preservation of the female vagina, uterus, neurovascular bundles, and any enhancement of the aforementioned techniques . Previous studies demonstrated that POPRC might not affect long-term survival and instead improve continence outcomes. However, most of the available studies are retrospective with limited cases in a single center. The current study primarily aims to urinary continence rate and long-term oncological outcomes of POPRC+OIN versus SRC+OIN in a prospective randomized controlled trial.
To compare the urinary continence rate and long-term oncological outcomes of pelvic-organ preserving radical cystectomy (POPRC) with orthotopic ileal neobladder (OIN) versus standard radical cystectomy(SRC) with OIN.
