The aim of the study: Orthotopic neobladder reconstruction is the preferred method of urinary diversion after radical cystectomy. We evaluated lower urinary tract function outcomes in patients after orthotopic neobladder using a patient questionnaire. Material and Methods: 40 patients who do radical cystectomy and orthotopic neobladder in EZ Aldean Al-Shi-Bany hospital at Sana'a Yemen between 2010-2018 patients with bladder cancer were included in a clinical trial, randomly assigned to Camey II pouch diversion after radical cystectomy. The patients were mailed a questionnaire 12-24 months after radical cystectomy including items on function, intermittent catheterization, and incontinence. Results: During the study between 2010-2018, 40 neobladder diversion were performed, day incontinence was 55% ((22 cases)) in the first 6 months post-surgery but improved to 12.5% ((5 cases)) after 1-year post-surgery also night incontinence was 62.5% ((25 cases)) in first 6 months postsurgical but improved to 15% ((6 cases)) 1-year post-surgery. Mean age at surgery of 40 patients were sub-segments analysis <50yeas was 12.5 % (5 case), 50-70 years was 65% (26 case), >70 years 22.5% (9 case). Conclusion: Ileal orthotopic neobladder have good lower urinary tract functional result, daytime and nighttime incomitance is coming in neobladder patients following surgery but improved with time. CIC is less common following surgery and improved with time. Keywords: Neobladder; Orthotopic; Lower Urinary Tract Function; Incontinence
