Transperitoneal or extraperitoneal laparoscopic radical prostatectomy: does the approach matter?

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Transperitoneal laparoscopic radical prostatectomy (TLRP) showed limitations in achieving normal continence post-surgery.
• Bladder dysfunction was hypothesized as a potential cause for reduced continence after TLRP.
• Extraperitoneal laparoscopic radical prostatectomy (ELRP) was proposed as an alternative approach to improve outcomes.

Purpose of the Study:

• To compare the outcomes of transperitoneal laparoscopic radical prostatectomy (TLRP) with extraperitoneal laparoscopic radical prostatectomy (ELRP).
• To evaluate the impact of surgical approach on operative time, blood loss, hospitalization, catheterization duration, and functional recovery (continence and erection rates).

Main Methods:

• A comparative study of 100 patients undergoing TLRP and 100 patients undergoing ELRP for prostate cancer (T3aN0M0 or less).
• Patients were operated on by a single surgeon.
• The study analyzed outcomes including operative time, blood loss, hospitalization, catheterization duration, and pad-free rates at 3 and 12 months, as well as erection rates at 12 months.

Main Results:

• ELRP demonstrated significantly shorter operative times, reduced blood loss, shorter hospital stays, and shorter catheterization durations compared to TLRP.
• While ELRP showed a lower 3-month pad-free rate (56% vs. 80%), the 12-month pad-free rate was higher (96% vs. 90%).
• ELRP also showed a higher 12-month erection rate (82% vs. 61%) compared to TLRP.

Conclusions:

• Extraperitoneal laparoscopic radical prostatectomy (ELRP) is a superior approach to transperitoneal laparoscopic radical prostatectomy (TLRP).
• ELRP offers advantages in terms of reduced operative time, shorter hospitalization, and improved early continence.
• The findings suggest ELRP may lead to better functional recovery in patients undergoing radical prostatectomy.
