Transperineal single-port robot-assisted radical prostatectomy with Si da Vinci surgical system: initial experience and description of technique

BACKGROUND: Single-port robotic-assisted radical laparoscopic prostatectomy has emerged as a novel robotic-assisted radical laparoscopic prostatectomy in recent years, arousing wide attention. However, single-port robotic-assisted radical laparoscopic prostatectomy using Si da Vinci surgical system has been rarely reported, especially via the transperineal approach. METHODS: We retrospectively collected 9 cases of prostate cancer patients who underwent transperineal single-port robot-assisted radical prostatectomy (t-spPARP) using Si da Vinci surgical system in our center from May 2020 to June 2020. The operation time, estimated blood loss (EBL), complications, changes in prostate-specific antigen (PSA) 3 months after surgery, and urinary continence recovery 6 months after surgery were analyzed. RESULTS: No perioperative complications were recorded. The median [interquartile range (IQR)] operation time was 350 [150] min and the median [IQR] EBL was 300 [100] mL. PSA levels were less than 0.01 ng/mL at 3 months postoperatively in all cases (undetectable in 8 cases). All the 9 patients recovered their urinary continence 6 months after surgery and merely two patients required pads during the day. CONCLUSIONS: t-spRARP was verified as a safe and feasible surgical alternative to treat patients with localized prostate cancer, especially for those whose prostate is small-volume or who had abdominal surgery history.
