The AdVance transobturator male sling for postprostatectomy incontinence: clinical results of a prospective evaluation after a minimum follow-up of 6 months.

Abstract

Transobturator male slings have been proposed to manage stress urinary incontinence (SUI) after prostatic surgery, but data are still lacking. To determine the safety and prospectively evaluate the clinical outcome after management of SUI after prostatic surgery by placement of a transobturator male sling. We conducted a prospective evaluation on 102 patients treated in a single center between 2007 and 2009 for mild to moderate SUI following prostatic surgery. Placement of a suburethral transobturator sling and clinical follow-up. Patients were evaluated by medical history, preoperative urodynamics, maximum flow rate measurement, 24-h pad test, and daily pad use. During follow-up, data on patients' pad use, complications, and answers to the Patient Global Impression of Improvement (PGI-I) questionnaire were collected. Cure was defined as no pad usage or one pad for security reasons and improvement as reduction of pads≥50%. Median follow-up was 13 mo (range: 6-26). Most patients (95%) presented post-radical prostatectomy incontinence (PRPI). Hospital stay was 2 d in 97 cases, and all patients were catheterized for 24h except two (48 h). Of 102 patients, 64 were cured, 18 were improved, and 20 were not improved. According to the PGI-I questionnaire, 85%, 11%, and 4% of patients described a respectively better, unchanged, and worse urinary tract condition, respectively. Previous radiation was associated with higher rate of failure (p=0.039). Neither severe complication nor postoperative urinary obstruction was noted during follow-up. Placement of a transobturator sling is a safe and effective procedure, giving durable results after >1 yr of follow-up. Further evaluation and high-quality controlled, randomized studies are needed to assess long-term efficacy and precise indications of this procedure for post-prostatic-surgery SUI management.
