A transobturator adjustable system for male incontinence: 30-month follow-up of a multicenter study

Abstract

Purpose: To report long-term results of the Argus T adjustable system for treatment of post-prostatectomy urinary incontinence (PPI). Materials and Methods: From October 2007 to August 2008, 37 patients with PPI were included in a prospective, single-arm, multicenter trial of treatment with the Argus T adjustable system (Promedon, Argentina). Preoperative evaluation included urine culture, urethrocystoscopy, urodynamic testing, 24-h pad weight test (PWT) and quality of life questionnaires. Patients were stratified according to baseline degree of incontinence (mild-moderate or severe). Postoperative evaluation included immediate PWT, quality of life questionnaires and daily use of pads at 1, 12 and 30 months. Results and Conclusions: One patient was lost to follow-up. At the 30-month follow- -up, 24/31 patients (77%) were dry, 3/31 (10%) improved and 4/31 (13%) were failures. In particular, in the mild-moderate group, 8/8 (100%) patients were dry. In the severe group, 20/28 patients (71%) were dry, 3/28 (11%) improved and 5/28 (18%) were failures. Median visual analogue scale (VAS) scores dropped from 9 (4-10) to 0.5 (0-10) and International Consultation on Incontinence Questionnaire Short Form scores from (ICIQ-SF) 19 (12-21) to 1 (0-10). Retrograde leak point pressure increased from 18 (5-29) to 35 (22-45) cm H2O after intraoperative adjustment. Complications included immediate postoperative infection in 2/36 patients (6%) and transient inguinal and/or perineal pain in 22/36 patients (61%). Argus T has a long-term high success rate (86% cure + improvement at the 30-month follow-up). Good outcomes were achieved even in severe incontinence cases and maintained for over 30 months.
