Purpose:
Inflatable penile prostheses and artificial urinary sphincters are used to treat men with erectile dysfunction and stress urinary incontinence, respectively. After prostate cancer treatment men often experience erectile dysfunction and stress urinary incontinence. Dual prosthetic implantation can improve the quality of life of these men. We evaluated reoperation outcomes in men who underwent dual implantation compared to each device implanted individually.
Materials And Methods:
We queried the SPARCS (New York State Department of Health Statewide Planning and Research Cooperative) database for men who underwent inflatable penile prosthesis and/or artificial urinary sphincter insertion between 2000 and 2014. The primary outcomes were the inflatable penile prosthesis and artificial urinary sphincter reoperation rates (revision, replacement or removal). Multivariable regression analysis was performed to assess the association of dual implantation with reoperation. Adjusted time to event analysis was also performed.
Results:
Median followup in the inflatable penile prosthesis cohort was 66 months (IQR 25-118) and in the artificial urinary sphincter cohort it was 69 months (IQR 27-121). Compared with men who received a penile prosthesis alone those with a penile prosthesis and an artificial urinary sphincter had a higher likelihood of undergoing inflatable penile prosthesis reoperation at 1 year (OR 2.08, 95% CI 1.32-3.27, p <0.01) and 3 years (OR 2.60, 95% CI 1.69-3.99, p <0.01). Compared with an artificial urinary sphincter alone patients with an inflatable penile prosthesis and an artificial urinary sphincter did not have a higher likelihood of undergoing artificial urinary sphincter reoperation at 1 year (p = 0.76) or 3 years (p = 0.73).
Conclusions:
Combined inflatable penile prosthesis and artificial urinary sphincter insertion portends a higher likelihood of inflatable penile prosthesis reoperation at 1 and 3 years. However, artificial urinary sphincter outcomes remain comparable. These findings should be used to better counsel patients about the risk of reoperation when undergoing dual implantation.

01:13Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
