Efficacy Of Modified Radical Prostatectomy Technique For Recovery Of Urinary Incontinence In High-Grade Prostate Cancer

BACKGROUND: This study was conducted to evaluate predictive factors of urinary continence recovery after radical prostatectomy (RP) for high-grade prostate cancer (PCa).METHODS: A total of 241 patients with high-grade (Gleason Score 8 or 9) PCa who underwent RP in a single Korean center between January 2011 and May 2018 were retrospectively reviewed. Urinary continence was defined as no pads use. Urinary continence was evaluated at 1, 3, 6, and 12 months after RP. Univariate and multivariate analyses were performed to determine the predictive factors of urinary continence recovery after RP.RESULTS: The mean age was 67.6 +/- 6.4 years, and the mean PSA was 18.7 +/- 21.1 ng/dL. A total of 197 (81.7%) patients underwent nerve-sparing RP, and 198 patients (822%) were continent 1 year after RP. Multivariate analysis showed that the age (odds ratio [OR]=1.091 [1.015-1.1721, P=0.018), Body Mass Index (BMI)(OR=1.227 [1.057-1.4241, P=0.007), and modified surgical technique (OR=0.109 [0.044-0.267], P<0.001) were independent factors for predicting urinary continence recovery after RR.CONCLUSIONS: Younger age, low BMI, and modified surgery were independent predictors of urinary continence recovery after RP in patients with high-grade PCa. These findings may help surgeons to give pre- and postoperative advice to patients with high-grade PCa about urinary continence recovery after RP.
