Abstract
- Purpose The artificial urinary sphincter is a common treatment of male urinary incontinence. We sought to characterize long-term rates of artificial urinary sphincter revision/removal and reimplantation, and associated risk factors. Materials and Methods We performed a population based, retrospective study using the Ontario Health Insurance Plan database of all male patients who underwent artificial urinary sphincter implantation from 1994 to 2013. Hospital, diagnostic and billing codes were used to identify patients. The Kaplan-Meier method and multivariable Cox proportional hazards models were applied to examine the cumulative incidence of artificial urinary sphincter reimplantation and revision/removal, and identify risk factors, respectively. Results A total of 1,632 male patients underwent initial implantation of an artificial urinary sphincter. The 10-year revision/removal and reimplantation rates were 34% and 27%, respectively. There was no difference between high and low volume hospitals or between community and academic hospitals in terms of revision/removal. A high level of comorbidity was associated with an increasing risk of removal/revision. The reimplantation rate was significantly lower in patients who underwent insertion at hospitals with the highest volume of surgery (HR 0.55, 95% CI 0.37–0.82, p <0.01). A high level of comorbidity was not associated with an increasing risk of reimplantation. Preimplantation radiotherapy was not significantly associated with the risk of reimplantation (p = 0.17) or revision/removal (p = 0.95). Other factors were not significantly associated with reimplantation or revision/removal. Conclusions Most men who undergo artificial urinary sphincter placement still have a device without repeat surgery 10 years following insertion. Radiotherapy does not increase the risk of repeat surgery. A high level of comorbidity was associated with an increasing risk of removal/revision. [ABSTRACT FROM AUTHOR]
