Impact of bariatric surgery on urinary incontinence in morbidly obese individuals.

Abstract

There is scanty evidence on the impact of bariatric surgery on urinary incontinence (UI) in the Asian population. Patients who underwent bariatric surgery from June 2018 to June 2019 were screened using the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) questionnaire. Patients having UI were identified and followed until 1year of surgery using the ICIQ-UI-SF. These were classified as having stress, urge, or mixed type of UI. The prevalence, change in scores, and the number of pads used were compared at baseline and at follow-up. A total of 148 patients underwent bariatric surgery of whom, 41 patients (M = 2, F = 39) had UI. Stress incontinence was seen in 70.7%, 19.5% had urge incontinence, and rest had the mixed type. Using logistic regression, it was found that female gender was the most important predictor of having UI (OR: 8.33). The prevalence of UI decreased from 27.7% at baseline to 8.1% at 6months and 3.4% at 12months. The mean ICIQ-UI-SF score improved from 8.76 (SD = 3.2) at baseline to 0.66 (SD = 2.1) at 12months of follow-up. The proportion of patients with UI using any number of pads decreased from 92.7% at baseline to 9.8% at 12months. There was a decrease in the number of patients having moderate to very severe UI from 35 (85.4%) at baseline to 2 (4.9%) at 12months. Proportion of patients showing resolution was highest among the stress incontinence group at 96.5%. Presence or absence of comorbidities did not significantly influence the ICIQ-UI-SF scores. Bariatric surgery leads to profound improvement in UI in obese individuals which is well sustained until 1year of follow-up. Resolution rates might be higher in Asian population.
