Radiotherapy is associated with reduced continence outcomes following implantation of the artificial urinary sphincter in men with post-radical prostatectomy incontinence
Objectives: The objective of this study is to present the outcomes of men undergoing implantation of artificial urinary sphincter, after treatment for prostate cancer and also to determine the effect of radiotherapy on continence outcomes after artificial urinary sphincter (AUS) implantation.

| Summary: | Objectives: The objective of this study is to present the outcomes of men undergoing implantation of artificial urinary sphincter, after treatment for prostate cancer and also to determine the effect of radiotherapy on continence outcomes after artificial urinary sphincter (AUS) implantation.
Material and Methods: A prospectively acquired database of all 184 patients having AUS insertion between 2002 and 2012 was reviewed, and demographic data, mode of prostate cancer treatment(s) before implantation, and outcome in terms of complete continence (pad free, leak free) were assessed. Statistical analysis was performed by Chi-squared and Fisher's exact tests.
Results: A total of 58 (32%) men had bulbar AUS for urodynamically proven stress urinary incontinence consequent to treatment for prostate cancer in this period. Median follow-up post-AUS activation was 19 months (1–119). Forty-eight (83%) men had primary AUS insertion. Twenty-one (36%) men had radiotherapy as part of or as their sole treatment. Success rates were significantly higher in nonirradiated men having primary sphincter (89%) than in irradiated men (56%). Success rates were worse for men having revision AUS (40%), especially in irradiated men (33%).
Conclusion: Radiotherapy as a treatment for prostate cancer was associated with significantly lower complete continence rates following AUS implantation. |
