Robotic assisted radical prostatectomy (RARP) offers comparable or better short-term outcomes than open radical retropubic prostatectomy (RRP), with improved functional recovery, but higher costs. Long-term data is still limited.
Area of Science:
- Urology
- Surgical Oncology
- Health Economics
Background:
- Robotic assisted radical prostatectomy (RARP) is increasingly used for localized prostate cancer.
- Limited comparative research exists on RARP versus conventional radical retropubic prostatectomy (RRP).
- Cost is a significant factor in determining optimal robotic surgery utilization.
Purpose of the Study:
- To review comparative effectiveness research of RARP versus RRP.
- To analyze outcomes including oncologic, functional, and cost-effectiveness.
Main Methods:
- Literature search of PubMed (2000-2014).
- Keywords: robot/robotic prostatectomy, open/retropubic prostatectomy, cost, resource utilization.
- Review of comparative effectiveness research.
Main Results:
- Short-term oncologic outcomes (surgical margins, recurrence-free survival) are equivocal or favor RARP.
- Functional outcomes (continence, potency) favor RARP.
- Cost favors RRP, and surgeon volume impacts efficiency and quality.
Conclusions:
- RARP shows promise for improved functional outcomes and similar short-term oncologic results.
- Longer-term studies are needed to evaluate RARP's true value and cost-effectiveness.
- Prospective trials are essential for determining RARP's utility in healthcare reform.
