Summary
Pure laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RAP) show similar oncological and functional outcomes for localized prostate cancer. Robot-assisted radical prostatectomy is associated with lower blood loss but is more costly.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Radical prostatectomy is a primary treatment for localized prostate cancer.
- Laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RAP) are minimally invasive surgical options.
Purpose of the Study:
- To compare the outcomes of pure laparoscopic radical prostatectomy (LRP) with robot-assisted radical prostatectomy (RAP).
Main Methods:
- A retrospective comparison of 100 patients with localized prostate cancer undergoing either LRP or RAP (50 each).
- Patient groups were matched for age, PSA, Gleason score, and clinical stage.
- Intraoperative data and early functional outcomes were analyzed.
Main Results:
- Mean surgical time was 235 min for LRP and 202 min for RAP (P > 0.05).
- Mean blood loss was significantly lower in RAP (206 mL) compared to LRP (299 mL) (P = 0.014), with no transfusions required for either group.
- Positive margin rates (14% LRP, 12% RAP) and early functional outcomes were similar, with no biochemical recurrence in either group.
Conclusions:
- Both LRP and RAP are feasible and beneficial for patients with localized prostate cancer.
- No significant surgical differences were observed between LRP and RAP.
- Robot-assisted radical prostatectomy (RAP) presents a higher cost compared to LRP.
