Overview

This study is a prospective, single-center clinical trial. It aims to establish an improved robotic-assisted radical prostatectomy for treating locally advanced prostate cancer. The technique evaluates the impact of preserving the anterior peritoneum of the bladder on postoperative bladder descent and urinary control recovery. A retrospective analysis compares this modified approach with traditional anterior approach surgery, assessing differences in oncological outcomes, early functional recovery, and postoperative complication rates. The goal is to provide new theoretical foundations and technical support for the prevention and treatment of postoperative urinary incontinence.

Eligibility

Inclusion Criteria:

1. prostate biopsy and clinical confirmation of high-risk prostate cancer (PSA > 20 ng/mL, Gleason score ≥ 8, or cT stage ≥ T2c) followed by robotic-assisted radical prostatectomy
2. multiparametric MRI (mpMRI) with a 3.0 T scanner for prostate or pelvic scans performed within 30 days before the operation at our center
3. Eastern Cooperative Oncology Group (ECOG) performance status score between 0 and 1
4. Complete clinical and prostate biopsy pathological data.
5. General health is good, with no infections, autoimmune diseases, hematologic disorders, or other malignancies.

Exclusion Criteria:

1. Presence of surgical contraindications.
2. refusal of enhanced mpMRI imaging.
