Summary
Robotic-assisted surgery for prostate cancer offers good functional recovery, but nerve preservation may increase positive surgical margins. Careful patient selection is key for optimal outcomes in robotic prostatectomy.
Area of Science:
- Urology
- Surgical Oncology
- Robotic Surgery
Background:
- Robotic-assisted laparoscopic radical prostatectomy (RLRP) is a growing alternative for localized prostate cancer.
- RLRP offers low morbidity and comparable oncologic and functional outcomes to traditional methods.
Purpose of the Study:
- To report initial experience with 300 consecutive RLRP cases.
- To evaluate the impact of selective interfascial nerve preservation (IFNP) on outcomes.
Main Methods:
- Prospective follow-up of 300 men undergoing RLRP between 2003 and 2005.
- Validated questionnaires used to assess urinary and sexual function.
Main Results:
- Mean operative time was 282 minutes; blood loss was 273 ml.
- 12-month return to baseline urinary function (71%) and continence (90.2%).
- 12-month return to baseline sexual function (53%) and potency (80.4%).
- Overall positive surgical margin (PSM) rate was 20.9%, higher in pT3 disease (52.1%).
- Posterolateral PSMs occurred more frequently with IFNP in pT3 disease (73% vs 33%, p=0.05).
Conclusions:
- Interfascial nerve preservation (IFNP) in RLRP is associated with favorable return of sexual potency.
- Posterolateral positive surgical margins are more frequent with IFNP.
- Careful patient selection for robotic surgery and nerve preservation is crucial for optimizing oncologic outcomes.
