Abstract Introduction Radical cystectomy (RC) is historically considered the gold standard treatment for muscle invasive and high‐risk non‐muscle invasive bladder cancer. However, this technique leaves the majority of patients of both sexes with poor sexual and urinary function. Organ‐sparing cystectomy (OSC) techniques are emerging as an alternative to the standard procedure to preserve these functions, without compromising the oncological outcomes. We present a systematic review and meta‐analysis of the published literature. Methods MEDLINE, Embase and Web of Science were systematically searched for eligible studies on 6 April 2021. Primary outcomes studied were both oncological outcomes, specifically overall recurrence, and functional outcomes, specifically sexual function, and daytime and nighttime continence. Odds ratios (OR) with 95% confidence intervals (95% CI) were calculated. The PROSPERO registration reference number was CRD42018118897. Results From 13 894 identified abstracts, 19 studies (1886 male and 305 female patients) were eligible for inclusion in this review. These studies included patients who underwent either whole prostate, prostate capsule, seminal vesicle, nerve, uterus, ovary, vagina and fallopian tube sparing techniques. Four studies included only female patients. Thirteen studies reported oncological outcomes, and overall recurrence rate was similar between the two groups (five studies; OR 0.73; 95% CI 0.38–1.40, p = 0.34). Thirteen studies reported on male sexual function. In men, OSC had significantly greater odds of retaining potency (five studies; OR 9.05; 95% CI 5.07–16.16, p |
