Radical retropubic prostatectomy can cause urinary incontinence due to sphincter weakness. Higher preoperative urethral closure pressure predicts faster continence recovery after prostatectomy.

Area of Science:

  • Urology
  • Surgical Oncology
  • Reconstructive Urology

Background:

  • Radical retropubic prostatectomy (RRP) is a common treatment for prostate cancer.
  • Urinary incontinence is a significant complication following RRP, affecting patient quality of life.
  • The timing and degree of continence recovery vary considerably among patients.

Purpose of the Study:

  • To investigate the impact of RRP on bladder and sphincter function using urodynamic parameters.
  • To identify predictors of immediate versus delayed urinary continence after RRP.
  • To elucidate the underlying reasons for post-prostatectomy incontinence.

Main Methods:

  • Prospective study involving 63 patients undergoing RRP.
  • Preoperative and postoperative urodynamic examinations were conducted.

  • Urodynamic data were analyzed to assess bladder and sphincter function at baseline and 2 months post-surgery.

    • Main Results:

    • Continence was regained by 68.2% at 2 months and 84.1% at 9 months post-RRP.
    • 15.9% of patients achieved immediate continence after catheter removal.
    • Sphincteric weakness was identified as the primary cause of incontinence; higher preoperative maximal urethral closure pressure correlated with better outcomes.

    Conclusions:

    • Sphincteric weakness is the predominant cause of urinary incontinence after RRP.
    • Patients with immediate postoperative continence demonstrated significantly higher preoperative and postoperative maximum urethral closure pressure.
    • Preoperative urodynamic assessment, particularly urethral closure pressure, may predict the likelihood and timing of continence recovery.
