Adjustable Continence Therapy Balloons in Female Patients with Stress Urinary Incontinence: A Systematic Review

Abstract

Introduction: The aim of this study was to perform a systematic review of studies reporting the outcomes of ACT® balloons in female patients with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD). Methods: In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) standards, a systematic search of the PubMed (Medline) and Scopus electronic database was performed in June 2022. Terms used for the query were (“female” or “women”) and (“adjustable continence therapy” OR “periurethral balloons”). Results: Thirteen studies were included. All were retrospective or prospective case series. The success rates ranged from 13.6% to 68% and the improvement rates from 16% to 83%. The intraoperative complication rate ranged from 3.5 to 25% and consisted of urethral, bladder, or vaginal perforations. The rate of postoperative complications varied from 11 to 56% without major complications. Between 6% and 38% of ACT® balloons were explanted and subsequently reimplanted in 15.2–63% of cases. Conclusion: ACT® balloons can be considered as an option to treat SUI due to ISD in female patients with a relatively modest success rate and quite a high complication rate. Well-designed prospective studies and long-term follow-up data are needed to fully elucidate their role.
