Summary

The extraperitoneal robotic-assisted simple prostatectomy (RASP) is effective for large prostates, offering results comparable to open surgery and transperitoneal RASP. This approach demonstrates efficiency and favorable outcomes in managing benign prostatic hyperplasia.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Benign prostatic hyperplasia (BPH) often requires surgical intervention for large prostates.
  • Traditional open simple prostatectomy can be associated with significant morbidity.
  • Robotic-assisted simple prostatectomy (RASP) offers a minimally invasive alternative.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of an extraperitoneal approach for RASP.
  • To replicate the vesicocapsular incision technique used in open surgery within a robotic setting.
  • To assess the efficacy of this technique in patients with large prostates (>80 cm³).

Main Methods:

  • Ten patients with large prostates underwent extraperitoneal RASP.
  • Preoperative assessment included uroflowmetry, PSA, postvoid residual, and IPSS.
  • Perioperative data and 1- and 6-month follow-up outcomes were prospectively recorded.

Main Results:

  • All ten procedures were successfully completed with minimal blood loss (mean 230 mL) and no transfusions.
  • Mean operative time was 122.5 minutes, with a mean catheterization period of 7.4 days.
  • Patients showed significant improvement in International Prostate Symptom Score (IPSS) postoperatively.

Conclusions:

  • The extraperitoneal approach for RASP is efficient for managing large prostates.
  • Outcomes are comparable to transperitoneal RASP and open simple prostatectomy.
  • This technique presents a viable, minimally invasive option for BPH treatment.
