Intravesical migration of AMS 800 artificial urinary sphincter and stone formation in a patient who underwent radical prostatectomy.
A patient who underwent placement of AMS 800 urinary sphincter for incontinence after salvage prostatectomy after radiation therapy failure, experienced urethral erosion of the cuff after 54 months. He was treated with cuff removal and prosthesis deactivation. Thirteen months later, a large bladder stone was removed transvesically, and it contained the reservoir. The remaining sphincter components were also removed. Patients with previous radiotherapy are particularly at risk for sphincter erosion, but intravesical displacement of the reservoir is a very uncommon complication.
