Initial experience with extraperitoneal robotic-assisted simple prostatectomy using the da Vinci SP surgical system

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Benign prostatic enlargement (BPE) significantly impacts lower urinary tract symptoms in men with prostates >80g.
• Robotic-assisted simple prostatectomy (RASP) is an established treatment for symptomatic BPE.
• The da Vinci SP robotic system offers a single-port approach, advancing minimally invasive surgery.

Purpose of the Study:

• To evaluate the initial institutional experience with RASP using the da Vinci SP robotic system for BPE.
• To assess the safety, efficacy, and outcomes of single-port RASP in patients with significant BPE.

Main Methods:

• Retrospective chart review of 10 patients undergoing SP-RASP for BPE (March-June 2019).
• Data collected included pre-operative, intra-operative, and post-operative parameters.
• Analysis focused on operative time, blood loss, complications, and catheter duration.

Main Results:

• All 10 procedures were completed using the single robotic cannula and one assistant port without conversion.
• Mean prostate volume was 104g; mean operative time was 172 minutes with 141mL blood loss.
• No intraoperative or immediate post-operative complications were observed; mean catheter time was 1.9 days.

Conclusions:

• Single-port RASP is a safe and effective surgical option for patients with significant BPE.
• The da Vinci SP system facilitates a minimally invasive approach with favorable early outcomes.
• Further comparative studies of SP-RASP versus multi-port RASP and other treatments are warranted.
