Cohort study 

研究目的:

本研究旨在通过回顾性队列分析,系统比较后入路保留 Retzius 间隙机器人辅助根治性前列腺切除术(RS-RARP)与前入路机器人辅助根治性前列腺切除术(RARP)对前列腺癌患者术后性功能恢复的影响,明确两种手术入路在性功能结局方面的差异,评估两种手术路径对患者术后生活质量的影响,为局限性前列腺癌患者的个体化手术策略提供循证依据。  

Objectives of Study:

This study aims to systematically compare, through a retrospective cohort analysis, the effects of posterior Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and standard robot-assisted radical prostatectomy (S-RARP) on postoperative sexual function recovery in patients with prostate cancer. The study seeks to clarify the differences in sexual function outcomes between the two surgical approaches and to evaluate their impact on patients’ postoperative quality of life, thereby providing evidence-based support for individualized surgical strategies in patients with localized prostate cancer.
