[Avoidable complications in the management of a patient with an artificial urinary sphincter].

All the patients who underwent implantation of an artificial urinary sphincter can have three types of complications: those coming from the own patient, mechanical complications and other aleatory ones. J. L. C. A., a 13-year-old boy with secondary neurogenic bladder, received the implantation of a model AUS 800 artificial urinary sphincter for urinary incontinence. After 15 months without problems, he was admitted in our hospital with pump erosion in the scrotum. He was operated on and the pump system was preserved. No plain roentgenograms were made neither before nor after surgical procedure. However, the balloon pressure reservoir was not seen in a control pielogram performed before his discharge from the hospital. Three months later the entire device should be removed because of infection. In the operation a cut off tube was found. A new artificial urinary sphincter was reimplanted and the cuff was placed around the bulbous urethra one year later. Retrospective analysis of this case can help to review the possible complications and their management.
