Summary

Laparoscopic extraperitoneal radical prostatectomy is safe for patients with higher body mass index or large prostates. These factors did not negatively impact outcomes, suggesting the procedure

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Radical prostatectomy is a standard treatment for localized prostate cancer.
  • Certain patient factors, including high body mass index (BMI), prior pelvic surgery, and large prostate size, are traditionally considered contraindications or risk factors for radical prostatectomy.
  • Laparoscopic extraperitoneal radical prostatectomy (LERP) offers a minimally invasive approach that may overcome some of these limitations.

Purpose of the Study:

  • To evaluate the impact of body mass index (BMI), previous pelvic surgery, and prostate weight on perioperative and pathological outcomes in patients undergoing laparoscopic extraperitoneal radical prostatectomy.
  • To determine if LERP is a viable option for patients with traditionally unfavorable surgical characteristics.

Published on: January 3, 2020

  • A retrospective analysis of 300 patients who underwent LERP between January 2004 and May 2005.
  • Patients were categorized into groups based on BMI (≤25, 25.1-30, 30.1-36, >36 kg/m²), prostate weight (≤20, 20.1-40, 40.1-60, >60 gm), and prior pelvic/prostatic surgery (yes/no).
  • Statistical analyses, including logistic regression and Kruskal-Wallis test, were used to assess outcomes.

Main Results:

  • High BMI, large prostate size, and prior pelvic surgery did not significantly affect positive surgical margin rates.
  • Prostate weight correlated with delayed Foley catheter removal (3 days, p=0.0005).
  • Higher BMI was associated with a slightly prolonged hospital stay (16 hours, p=0.02), and prostates >40 gm had slightly increased blood loss (56 cc, p=0.03), without impacting transfusion rates.

Conclusions:

  • Laparoscopic extraperitoneal radical prostatectomy can be safely performed in patients with high BMI, large prostates, or a history of pelvic surgery.
  • The procedure does not appear to increase perioperative morbidity in these complex cases.
  • LERP offers potential benefits for obese patients and those with large prostates seeking surgical treatment for localized prostate cancer.
