Review of Single-surgeon 10-Year Experience With Artificial Urinary Sphincter With Report of Sterile Cuff Erosion Managed Nonsurgically

ObjectiveTo review our experience with artificial urinary sphincter (AUS) and to consider the role of nonsurgical management of sterile AUS cuff erosion.MethodsWe retrospectively reviewed our 10-year experience with AUS implantation, including complication rates. We focus on the outcomes of eroded sphincters including 2 unique patients who were managed nonsurgically for sterile cuff erosion.ResultsBetween 2002 and 2012, 126 AUS units were implanted in 79 adult male patients by single surgeon (A.K.S.). Twenty-five patients (31.6%) required at least 1 additional procedure because of urethral atrophy (22.8%) or erosion or infection (8.9%). In addition, 2 patients with congenital anomalies underwent AUS implantation at bladder neck and were followed up nonsurgically for several years after cuff erosion. Both refused surgical management and have since remained continent and infection-free despite chronic erosion for 15 years' duration in 1 patient and for 5 years' duration in the other. Of note, the patient with the longer duration of erosion developed bladder stones requiring surgical removal.ConclusionOur AUS complication rates are consistent with those of prior series. Our unique experience with 2 patients suggests that immediate removal of AUS after sterile cuff erosion may occasionally be instituted only in difficult cases where repeat AUS implantation is not possible. To our knowledge, this is the first report of nonsurgical management of eroded AUS cuff in the literature. Larger prospective series concerning patient selection for salvaging eroded AUS may be warranted.
