Artificial urinary sphincter (AUS) implantation improved urodynamic parameters in men with post-prostatectomy incontinence and bladder dysfunction. Mild bladder abnormalities did not prevent successful AUS outcomes for stress urinary incontinence (SUI).
Area of Science:
- Urology
- Urogynecology
- Surgical Innovation
Background:
- Post-prostatectomy incontinence often presents with detrusor overactivity (DO) and/or reduced bladder compliance.
- Urodynamic assessment is crucial before artificial urinary sphincter (AUS) implantation.
Purpose of the Study:
- To evaluate changes in urodynamic parameters after AUS implantation in patients with post-radical prostatectomy (RP) stress urinary incontinence (SUI) and pre-existing bladder dysfunction.
Main Methods:
- Retrospective review of 16 patients with SUI post-RP and urodynamic bladder abnormalities.
- Comparison of urodynamic parameters before and after AUS implantation.
Main Results:
- Significant improvements observed in bladder capacity (p=0.05) and compliance (p=0.03) post-AUS.
- A decrease in detrusor overactivity (DO) from 50% to 25% was noted.
- Mean pad usage reduced from 5.7 to 1 pad per day.
Conclusions:
- Preoperative urodynamic abnormalities, including mild bladder dysfunction, improved following AUS implantation.
- Mild bladder dysfunction should not be considered a contraindication for AUS placement in SUI post-RP patients.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
