Urinary incontinence after obstetric-gynecological surgery – urodynamic studies

Abstract

Summary Objectives: The aim of the study was to estimate the prevalence rate of patients with urinary incontinence after pelvic surgery, as well as the distribution of urinary incontinence types depending on the type of surgery. Material and methods: 200 consecutive female patients, aged between 33 and 85 years old, administered to urodynamic diagnostic due to urinary incontinence, were included in the study. After collecting medical history and performing a urogynecological examination, a urodynamic study was done. We estimated the relation between urinary incontinence types, bladder activity and type of surgical procedure. Results: 35,5% of patients had undergone obstetric-gynecological operations (abdominal hysterectomy was most frequent, followed by vaginal reconstructive operations, Caesarean sections, adnexal operations and vaginal hysterectomy). We observed 56% of stress urinary incontinence (SUI), 35% of mixed urinary incontinence (MUI) and 9% of overactive bladder (OAB). Among patients with SUI, we found 55% women after abdominal hysterectomy, 5% after vaginal hysterectomy, 20% after adnexal operations, 15% after vaginal reconstructive operations and 5% after Caesarean section. In the group with MUI, 40% patients were after vaginal reconstructive operations, 32% after Caesarean sections, 20% after abdominal hysterectomy and 8% after adnexal operations. Among women with OAB we noticed 33% patients after vaginal reconstructive operations, 33% after abdominal hysterectomy, 17% after Cesarean sections and 17% after vaginal hysterectomy. Conclusions: The results of the study show that patients after obstetric-gynecological surgery procedures make up 30% of all urinary incontinence cases. Distribution of urinary incontinence types in the group of operated women is similar in the entire investigated group. Abdominal hysterectomy and reconstructive vaginal operations are clearly connected with urinary incontinence.
