Participants undergo robot-assisted laparoscopic radical prostatectomy(RAPA) via an integrated Posterior-Anterior-Lateral (PAL) approach using the da Vinci system.

• Posterior:** mobilize sigmoid colon, incise rectovesical peritoneum, dissect vas deferens and seminal vesicles, open Denonvilliers' fascia, create a fascial window at prostate base.
• Anterior:** enter retropubic space, preserve endopelvic fascia, puboprostatic ligaments, dorsal venous complex, expose bladder neck and anterior prostate.
• Lateral:** dissect lateral bladder neck/prostate base, expand triangular space, retract seminal vesicle through posterior window, incise bladder neck, control vascular pedicles, perform atraumatic neurovascular bundle dissection, preserve urethral length.
• Prostate removal** is followed by **continuous urethrovesical anastomosis** with 3-0 barbed suture.

**Intended Purpose of Intervention:** Assess perioperative outcomes, early functional recovery, and oncologic safety of PAL-RAPA

Participants undergo robot-assisted laparoscopic radical prostatectomy via a posterior-only approach using the da Vinci system. The procedure includes: mobilization of the sigmoid colon, incision of the rectovesical peritoneum, dissection of vas deferens and seminal vesicles, opening of Denonvilliers' fascia, and creation of a fascial window at the prostate base. Prostate removal is followed by continuous urethrovesical anastomosis using a 3-0 barbed suture.

PAL combined approach was performed to resect the prostate

was defined as the use of zero to one safety pad per day without any involuntary leakage.Immediate continence was defined as continence within seven days after catheter removal, while early continence was defined as continence achieved within three months.
