10 years follow‐up after mid‐urethral sling implantation: high rate of cure yet a re‐occurrence of OAB‐symptoms

Abstract

AIMS: To assess the long-term outcome of mid-urethral slings regarding urinary incontinence (UI) and lower urinary tract symptoms and to identify risk factors for an unsatisfactory outcome. METHODS: Analysis of a prospective institutional database. For the current analysis only women who reached the 10 years follow-up were eligible. Outcome was assessed using a detailed, non-validated questionnaire on continence status and on several aspects of lower urinary tract function. RESULTS: A total of 256 women were operated during 1999-2004, in 139 (54.3%), a 10 years follow-up was available and these patients were included. Mean age at surgery was 63 years. At the 2, 5, and 10 years follow-up, the percentages of women reporting 0-1 pads/day were 96.4%, 97.1% and 88.5%, respectively. More than 95% of the patients reported no stress UI at the 2, 5, and 10 years follow-up. At baseline, urgency was reported by 61.2%, this figure dropped to 17.3% at 2 years and increased thereafter to 32.4% (5 years) and 41.7% (10 years). De novo urgency was present in 3.6% after 2 years, in 10.8% after 5 years, and 14.4% after 10 years. The percentage of patients with a high degree of treatment satisfaction declined from 79.1% at 2 years to 70.5% at 5 years, and 62.6% at 10 years. Risk factors for an unsatisfactory long-term outcome were advanced age, the presence of urgency, nocturia, and decreased bladder capacity at baseline. CONCLUSIONS: This study confirms the excellent long-term efficacy of mid-urethral slings regarding the management of stress UI. A substantial number of women develop OAB-symptoms after the procedure that largely contribute to outcome dissatisfaction. Neurourol. Urodynam. 36:614-619, 2017. © 2016 Wiley Periodicals, Inc.
