RESUMO
INTRODUCTION: Treatment of pelvic organ prolapse (POP) associated with stress urinary incontinence (SUI) is a surgical challenge. Surgeons may perform combined prolapse and incontinence surgery or may correct prolapse first and evaluate incontinence afterwards. We present a prospective study to evaluate the effect of abdominal sacrocolpopexy (ASC) on urethral anatomy and continence using dynamic magnetic resonance imaging (MRI). METHODS: Twenty females with concomitant apical prolapse and SUI due to urethral hypermobility were included. Patients with intrinsic sphincteric deficiency (ISD) were excluded. All patients underwent ASC operation as a sole treatment without anti-incontinence procedure. Patients were informed they may need anti-incontinence procedure afterwards. Symptom-specific questionnaires assessing prolapse, incontinence, sexual function and quality of life (QoL), dynamic MRI and pressure flow urodynamic study were administered before and after surgery. RESULTS: Mean age was 53 years. All patients had apical prolapse; four with cystocele, and five with rectocele. Urethral hypermobility was positive in all patients. After performing ASC, all patients reported significant improvement of all prolapse and incontinence questionnaires as well as QoL and sexual function. Significant improvement of incontinence parameters on dynamic MRI (bladder neck descent, posterior urethrovesical angle and urethral inclination angle) was observed after ASC. Similarly, significant change in the position of the leading edge of prolapse and anorectal junction was observed. CONCLUSIONS: In patients with prolapse and urethral hypermobility, ASC may return bladder neck and urethral anatomy towards normal as proved by dynamic MRI. However, further studies on larger number of patients with longer follow-up period are required.
