Objective:
To investigate the application of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) in the treatment of early-stage prostate cancer.
Methods:
We retrospectively analyzed the clinical data about 10 cases of early-stage prostate cancer treated by RS-RARP with the Da Vinci Robot Surgical System from September to October 2016.
Results:
All the operations were successfully completed without positive surgical margins. The operation time was 170-250 min ([196±25] min), the intraoperative blood loss was 150-500 ml ([260±128] ml), the postoperative hospital stay was 6-7 days, and the catheterization time was 14 days. Urinary continence occurred after catheter removal in 1 patient and was recovered 1 month later.
Conclusions:
RS-RARP is a safe, effective and reliable method for the treatment of prostate cancer and conducive to the early recovery of urinary continence.
