Not all surgical records were available for all patients, percentages and averages were based on available data for each variable. Primary: first procedure done for PPUI. Secondary: previous AUS placement, sling, or bulking done at an outside institution. Revision reason refers to mechanical failure of the device (e.g., cuff leak, tubing breakdown), urethral erosion under the cuff, infection of the device, or replacement of a previously explanted device. Revision component refers to total device replacement or of individual device components.
AUS, artificial urinary sphincter; SD, standard deviation.
