Abstract
OBJECTIVES
To investigate the safety profile and short-term outcome of super-veil nerve-sparing extraperitoneal single-port robotic-assisted radical prostatectomy (espRARP) on da Vinci Si platform.
METHODS
From December 2018 to March 2021, 106 consecutive patients with treatment-naive prostate cancer were prospectively included. espRARP was performed on da Vinci Si surgical platform. Operative time, estimated blood loss, Clavien-Dindo complication classification, continence, potency recovery, quality-of-life scores, and postoperative prostate-specific antigen (PSA) were documented.
RESULTS
Patients aged 52-79 years (mean ± SD, 64.8 ± 6.15 yrs), with a median PSA of 9.2 ng/ml (IQR: 6.70, 16.83) and median prostate volume of 31.9 ml (IQR: 30.01, 38.54). 95.28% (101/106) were clinically localized. All patients underwent espRARP successfully with no open conversions. Operative time was 94.2 ± 30.26 min with an estimated blood loss of 68.5 ml (range, 50-120 ml). No Grade III complications or above were documented. Positive surgical margin was 17.9% (19/106). Median pain score at discharge was 0 (IQR: 0, 1.75) without use of opioid narcotics. Postoperative length of stay was 3 days (IQR: 1, 3), in which 28 patients were discharged within 24 h. Instant, 1-, 3-, and 6 month continence recovery was 18.9, 45.3, 79.2, 93.4, and 96.4%, respectively. Of the 43 patients who received nerve-sparing procedures, 13 (30.23%) resumed potency 6 months postoperatively. 12 month biochemical recurrence-free survival was 92.77% (77/83).
CONCLUSIONS
Extraperitoneal single-port robotic-assisted radical prostatectomy is a safe and feasible technique. Combined with super-veil nerve-sparing procedures, it may provide satisfactory outcome in short-term functional recovery.
