How Artificial Urinary Sphincter Impacts Toileting Habits 1 Year After Implantation

Area of Science:

• Urology
• Men's Health
• Surgical Outcomes

Background:

• Artificial urinary sphincter (AUS) is a gold standard for moderate to severe male stress urinary incontinence (SUI).
• Patient-reported outcomes and behaviors post-AUS implantation require further investigation.

Purpose of the Study:

• To evaluate the association between self-reported toileting behaviors and quality of life (QOL) after AUS implantation.
• To assess patient satisfaction and continence outcomes following AUS implantation.

Main Methods:

• Prospective, multicenter study (AUSCO) involving 115 men with primary SUI receiving AMS 800 AUS.
• Data collected on incontinence events, toileting habits, device use, and QOL (I-QOL, IIQ-7, EQ-5D-5L) at 3, 6, and 12 months.
• Exclusion of patients with predominant overactive bladder symptoms.

Main Results:

• High success rates: 94% achieved ≥50% reduction in pad weight, 92% reported satisfaction at 12 months.
• Significant QOL improvements (p < 0.001) correlated with reduced incontinence and ease of device use.
• Toileting habits showed minimal change and were not associated with satisfaction; postvoid dribbling persisted in 68%.

Conclusions:

• AUS implantation offers high satisfaction and significant QOL improvement in men with SUI at one year.
• Ease of use and effectiveness are primary drivers of satisfaction.
• Toileting behaviors are largely unaffected, informing preoperative counseling and patient selection.
