Implantation asynchrone d’une prothèse pénienne (AMS 700) chez des patients avec un sphincter urinaire artificiel (AMS 800) : quels sont les résultats fonctionnels de l’AMS 1500 ?

Abstract

To report the functional results and morbidity after metachronous implantation of an AMS 800 artificial urinary sphincter (AUS) and an AMS 700 inflatable penile prosthesis (IPP). From the 250 patients treated in our department between 2000 and 2011 for the insertion of an AUS, we retrospectively selected patients who also underwent implantation of an IPP. The following data were recorded: age, aetiology of urinary incontinence (UI) and erectile dysfunction (ED), treatment history of UI/ED, date of insertion of the AUS and the IPP and time gap between the two implants. We evaluated both the pad-test and the number of protective pads used per day, before and after AUS insertion. We also analysed the IIEF5 score before and after IPP. Patients were reviewed at 3, 6 and 12 months and annually thereafter. In total, five patients were included. The median age was 69 years. The median follow-up after IPP was 22.6 months and the time gap between the two implants was 50 months. The aetiology of UI and ED was prostate surgery in four cases. Complete continence without leakage was observed in three patients and the IIEF5 score increased from 6.6 preoperatively to 22.2 for four patients. One patient developed a urethral erosion of the AUS cuff 6 months after implantation of the IPP. The AUS cuff has been explanted but the patient remains continent with the IPP cylinders semi-inflated. From our small study, it appears that the combined use of an AMS 800 AUS and an AMS 700 IPP was a feasible and efficacious option in patients with concomitant refractory UI and ED.
