Summary

Preserving neurovascular bundles and bladder neck during radical retropubic prostatectomy (RRP) reduces complications. However, preserving puboprostatic ligaments with bladder neck preservation does not improve continence after RRP.

Area of Science:

  • Urology
  • Oncology
  • Surgical Techniques

Background:

  • Radical retropubic prostatectomy (RRP) is a common treatment for prostate cancer.
  • Urinary incontinence and erectile dysfunction are significant morbidities following RRP.
  • Optimizing surgical techniques aims to improve functional outcomes and oncological control.

Purpose of the Study:

  • To evaluate the impact of preserving puboprostatic ligaments and bladder neck on urinary incontinence after RRP.
  • To assess the effect of neurovascular bundle preservation on erectile function recovery post-RRP.
  • To determine the risk of positive surgical margins with precise bladder neck and apical dissection techniques.

Main Methods:

  • RRP was performed using three techniques: tennis racquet reconstruction, bladder neck preservation, or bladder neck and puboprostatic ligament preservation.

  • Continence and surgical margin status were assessed for all techniques.
  • Potency recovery and margin status were evaluated based on the preservation of one, both, or no neurovascular bundles.

    • Main Results:

    • Social continence rates were 90% (tennis racquet), 100% (bladder neck preservation), and 89% (bladder neck and puboprostatic ligament preservation).
    • Time to continence recovery was 2.3 months (tennis racquet), 2.9 months (bladder neck preservation), and 4.3 months (bladder neck and puboprostatic ligament preservation).
    • Bilateral nerve-sparing surgery was performed in 72% of potent patients; positive margins occurred in 9% of these, primarily at the apex (3%).

    Conclusions:

    • Preservation of neurovascular bundles and bladder neck during RRP reduces morbidity with minimal risk of positive surgical margins.
    • Preserving both the bladder neck and puboprostatic ligaments delays continence recovery without improving overall continence rates.
