Independent Factors Affecting Postoperative Short-Term Urinary Continence Recovery after Robot-Assisted Radical Prostatectomy

Background. Our team had firstly applied the transvesical approach to robot-assisted radical prostatectomy (RARP) in patients afflicted with localized prostate cancer (PCa). The present study aims to present the postoperative recovery of urinary continence (UC) following the anterior, transvesical, and posterior approaches to RARP for localized PCa and evaluate the independent predictors to early UC recovery after RARP. Methods. Patients harboring localized PCa and receiving anterior, transvesical, and posterior approaches to RARP between January 2017 and June 2020 were enrolled in this analysis. Results on UC recovery were compared between these three approaches with the Kaplan–Meier method. All clinical and pathological variables were further analyzed via univariable and multivariable regression analysis to determine the independent factors contributing to short-term UC recovery after RARP. Results. A total of 135, 73, and 66 instances were included in the anterior, transvesical, and posterior groups, respectively. Over the postoperative follow-up period, both the transvesical and posterior approaches showed an advantage over the anterior approach in promoting postoperative UC recovery (both values ). Multivariable analysis results point patient age, prostate volume, surgical approach, and nerve-sparing technique as independent factors that affect postoperative UC recovery after RARP. Conclusions. The application of transvesical approach to RARP for localized PCa could obtain promising outcomes in terms of postoperative UC recovery. In addition, surgical strategies encompassing the nerve-sparing technique and the Retzius-sparing procedures, namely, the transvesical or posterior approach, during RARP could independently enable early achievement of postoperative continence.
