[Adjustable continence therapy balloons in women: Evolution of efficacy within the 24 months following implantation]. / Ballons ACT chez la femme : évolution de l'efficacité au cours des 24 mois suivant l'implantation.

PURPOSE: To analyze the functional outcomes over time of ACT balloon in women with stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD). METHOD: All patients with SUI secondary to ISD who underwent bilateral ACT balloon implantation between September 2008 and November 2015 and regularly monitored for a period of at least 24 months were eligible. The results were studied at 6, 12 and 24 months. Efficacy was defined as: Success - maximum 1 safety pad per day and visual analogue scale (VAS) rating≥9/10. Improvement - decrease in the number of pads used per day and VAS≥5/10. Failure - increase or stability of the number of pads used per day and/or VAS<5/10. Failure was considered as primary when it occurred without any success or improvement. It was considered as secondary when it occurred after an initial period of success or improvement. RESULTS: 18 patients were monitored during 24 months. The success rate was respectively 17 %, 33 % and 33 % at 6, 12 and 24 months of follow-up. The improvement rate was respectively 61 %, 39 % and 17 % at 6, 12 and 24 months of follow-up. The primary failure rate was 22 %. The secondary failure rate was 6 % at 12 months and 33 % at 24 months of follow-up. CONCLUSION: ACT balloon efficacy tends to decrease with time requiring a long-term follow-up of implanted patients. LEVEL OF EVIDENCE: 4.
