Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a retrospective, single-center clinical trial. It aims to retrospectively analyze the immediate postoperative urinary continence recovery in prostate cancer patients who underwent Retzius-sparing robot-assisted radical prostatectomy in the investigators' center. Based on the general conditions of patients, relevant perioperative clinical indicators, and parameters related to the sphincter and prostate gland measured by MRI, it explores the influencing factors of immediate urinary continence recovery after Retzius-sparing robot-assisted radical prostatectomy in prostate cancer patients and constructs a relevant prediction model, thereby providing clinical guidance value for predicting immediate postoperative urinary continence recovery.

The Retzius-sparing robot-assisted radical prostatectomy group

In 2010, Italian urologist Dr Bocciardi carried out the first clinical practice of separation and resection of the prostate via the vesicorectal fossa, and this new surgical procedure was called Retzius-sparing Robotic Assisted Radical Prostatectomy (RS-RARP). In recent years, the posterior approach extrafascial technique of RS-RARP which has been used to widely resect the prostate and its surrounding fascia and neurovascular bundles, compared with RS-RARP, has been proposed to provide more complete resection of the tumour and reduce the rate of positive margins. The patients are included into the Retzius-sparing robot-assisted radical prostatectomy group group who undergo the posterior approach extrafascial technique of RS-RARP.
