Summary
Robotic-assisted radical prostatectomy (RARP) is feasible in new centers, offering improved functional outcomes and reduced blood loss compared to open retropubic radical prostatectomy (RRP). While RARP has a longer operative time, it leads to shorter hospital stays and catheterization durations.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Robotic-assisted radical prostatectomy (RARP) offers potential advantages in minimally invasive surgery due to enhanced visualization and dexterity.
- Laparoscopically naive surgical centers require evaluation of RARP's early outcomes compared to established open retropubic radical prostatectomy (RRP).
Purpose of the Study:
- To compare the early oncological, perioperative, and functional outcomes of RARP versus RRP in a center with no prior laparoscopic experience.
- To assess the learning curve and feasibility of RARP for surgeons new to minimally invasive techniques.
Main Methods:
- A prospective cohort of 120 patients undergoing RARP was compared to a historical control group of patients who underwent RRP.
- Surgeons were laparoscopically naive, performing both RARP and RRP.
- Outcomes including oncological (positive surgical margins), perioperative (blood loss, operative time, length of stay, catheter duration), and functional (continence, potency) were evaluated at 3, 6, and 12 months post-surgery.
Main Results:
- Oncological outcomes, measured by positive surgical margins, were equivalent between RARP (22%) and RRP (25%).
- RARP demonstrated significantly lower estimated blood loss (200 mL vs. 800 mL), shorter catheterization duration (6 vs. 7 days), and reduced length of stay (3 vs. 6 days) compared to RRP.
- Functional outcomes showed superior continence and potency recovery rates for RARP at 6 and 12 months post-surgery.
Conclusions:
- RARP is a feasible procedure in a laparoscopically naive center, providing comparable early oncological outcomes to RRP.
- RARP offers significant advantages in reduced blood loss, shorter hospitalization, and improved functional recovery (continence and potency) compared to RRP.
- While RRP is a faster procedure, RARP's benefits in perioperative and functional results support its adoption in minimally invasive prostate surgery.
