Recurrent or persistent urinary incontinence in patients with the artificial urinary sphincter: diagnostic considerations and management.


Clinical experience in the selection of patients for implantation of the artificial urinary sphincter and the surgical techniques for sphincter implantation indicate a need to provide suitable guidelines for patient followup and the management of post-implantation urinary incontinence. Two types of post-implantation incontinence are recognized: 1) immediate post-activation incontinence and 2) delayed or recurrent incontinence. The potential causes, and the diagnostic and management techniques are dependent on not only an understanding of device function but also on the use of already available clinical tools. Physical examination, inflate-deflate roentgenograms of the device, cystoscopy and retrograde urethrography each has an important role in determining the cause and, therefore, the appropriate remedy for the restoration of urinary control. Causes that result in loss of urinary control after implantation include improper operation of the device by the patient, detrusor hyperreflexia, occlusive cuff erosion, improper cuff sizing and device malfunction. Proper recognition of the precise cause of post-implantation incontinence and workable guidelines for management will provide for effective assurance that urinary control can be restored successfully.
