Laparoscopic simple prostatectomy (LSP) and robot-assisted simple prostatectomy (RASP) are safe and effective treatments for enlarged prostates. Both procedures offer significant improvements in patient outcomes.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition causing bladder outlet obstruction.
  • Simple prostatectomy is a surgical option for BPH, with minimally invasive approaches gaining popularity.

Purpose of the Study:

  • To compare the effectiveness and outcomes of laparoscopic simple prostatectomy (LSP) versus robot-assisted simple prostatectomy (RASP).

Main Methods:

  • Retrospective analysis of consecutive LSP and RASP cases (2003-2014) from three institutions.
  • Paired analysis of functional and surgical outcomes.
  • Multivariate analysis to identify predictors of a favorable "trifecta" outcome.

Main Results:

  • 319 patients underwent minimally invasive simple prostatectomy.

  • Prostate volume was larger in the RASP group.
  • No significant differences in catheterization time or hospital stay.
  • Higher overall postoperative complications in RASP group, but no difference in major complications.
  • Both LSP and RASP showed significant subjective and objective improvements.
  • Age and BMI were predictors of favorable trifecta outcome.

    • Conclusions:

    • Laparoscopic simple prostatectomy (LSP) and robot-assisted simple prostatectomy (RASP) are safe and effective minimally invasive treatments.
    • Both techniques provide significant improvements for patients with bladder outlet obstruction due to large prostates.
