Five-Year Outcomes and Learning Curve of ProACT for Postprostatectomy Incontinence
Overview
This retrospective single-center study evaluates the five-year outcomes and learning curve of adjustable continence therapy (ProACT) in managing postprostatectomy incontinence (PPI). The study highlights surgical success rates, complication profiles, and the impact of surgeon experience on patient outcomes.
Background
Postprostatectomy incontinence (PPI) affects up to 20% of patients after radical prostatectomy, significantly impairing quality of life. Stress urinary incontinence due to sphincter dysfunction is the predominant type, often managed surgically when conservative therapy fails. The artificial urinary sphincter (AUS) is the gold standard but has limitations including patient manipulation requirements. ProACT, a minimally invasive adjustable balloon system, offers an alternative with comparable efficacy and fewer complications, particularly beneficial for patients with impaired hand function. However, ProACT implantation is technically challenging, and the learning curve for surgeons remains underexplored.

Key Findings
ProACT implantation achieved a 53% surgical success rate defined as 0–1 pad per day use.
The overall complication rate was 31%, with device explantation occurring in 27% of cases.
ProACT is less invasive and requires shorter surgical time compared to artificial urinary sphincter implantation.
The device requires no patient manipulation during urination, benefiting patients with impaired hand function.
Complication and revision rates decrease as surgeons gain experience, indicating a significant learning curve.
ProACT can be easily removed in an outpatient setting if complications arise.
Clinical Implications
ProACT offers a viable, less invasive alternative to artificial urinary sphincters for managing PPI, especially in patients with limited manual dexterity. Understanding the learning curve is essential for centers considering adoption, as surgeon experience significantly impacts complication and revision rates. The ability to adjust balloon volume post-implantation allows for individualized treatment optimization.
Conclusion
Adjustable continence therapy with ProACT demonstrates comparable efficacy to artificial urinary sphincters with fewer complications and easier management, though surgical expertise is critical to optimize outcomes. Increased surgeon training and experience can reduce complications and improve patient satisfaction over time.
