Comparison of the Integrated Posterior-Anterior-Lateral Approach and the Posterior Approach in Robotic Radical Prostatectomy

A Prospective, Randomized Controlled Study Comparing the Integrated Posterior-Anterior-Lateral (PAL) Approach and the Posterior Approach in Robot-Assisted Radical Prostatectomy: Evaluation of Perioperative Outcomes, Postoperative Functional Recovery, and Oncologic Control

This study aims to compare perioperative, pathological, and early functional outcomes of PAL （Posterior, Anterior and Lateral）combined approach RARP and posterior approach (with Retzius space preserved) RARP in the treatment of prostate cancer.The main question it aims to answer was:

What is the early therapeutic efficacy of robot-assisted laparoscopic radical prostatectomy using the combined posterior, anterior, and lateral (PAL) approach, and how does it compare with the traditional posterior approach? Participants were randomly assigned to undergo either robot-assisted laparoscopic radical prostatectomy using the PAL (posterior-anterior-lateral) approach or the classic posterior approach.
