Summary
Single-port (SP) robot-assisted radical prostatectomy (RARP) is safe and feasible, showing comparable short-term functional outcomes to multiport (MP) RARP. However, SP-RARP demonstrated lower nerve-sparing rates in this comparative study.
Area of Science:
- Urology
- Surgical Oncology
- Robotic Surgery
Background:
- Robot-assisted radical prostatectomy (RARP) is a standard treatment for prostate cancer.
- Single-port (SP) RARP offers potential advantages in minimally invasive surgery.
- Comparing SP-RARP with traditional multiport (MP) RARP is crucial for understanding its efficacy and outcomes.
Purpose of the Study:
- To compare the perioperative outcomes of SP-RARP and MP-RARP.
- To evaluate functional recovery, including continence and potency, after both procedures.
- To assess nerve-sparing outcomes in patients undergoing SP-RARP versus MP-RARP.
Main Methods:
- Retrospective review of 40 SP-RARP and 129 MP-RARP cases.
- Propensity score matching (1:1) to create comparable cohorts.
- Analysis of perioperative parameters, surgical margins, and functional outcomes (continence, potency, nerve sparing).
Main Results:
- No significant differences were observed in console time, operation time, estimated blood loss, positive surgical margins, or 3-month continence and potency rates between SP-RARP and MP-RARP.
- SP-RARP showed significantly lower rates of complete nerve sparing compared to MP-RARP.
- Despite lower nerve-sparing scores, SP-RARP demonstrated comparable short-term functional results.
Conclusions:
- SP-RARP is a safe and feasible alternative to MP-RARP for radical prostatectomy.
- Short-term functional outcomes, including continence and potency, are comparable between SP-RARP and MP-RARP.
- Further investigation is needed to optimize nerve-sparing techniques in SP-RARP.
