[Retzius-sparing robot-assisted laparoscopic radical prostatectomy for early-stage prostate cancer (with video)].

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.
