Purpose:
The incidence of nocturia is increased in obesity, which causes significant negative impact on quality of life. Bariatric surgery is a reliable method in which to achieve major weight loss and this study aims to determine the effect of bariatric surgery on nocturia and other lower urinary tract symptoms (LUTS) in men and women.
Materials And Methods:
Retrospective study of patients undergoing bariatric surgery had pre- and post-operative questionnaires using the validated International Prostate Symptoms Score (IPSS) to assess nocturia between 2018 and 2021. The primary outcome was effect of bariatric surgery on nocturia RESULTS: A total of 99 patients were included with median age of 52.9 (44.9-60.2) and 83.8% being female. The median weight was 129.9kg (110-151.9) and median BMI was 45.5 (41.4-53.4). Improvements were demonstrated in all criteria assessed in IPSS and nocturia significantly improved with a decrease in 1.14 points (p < 0.05). Linear regression analysis showed that, in the post operative period assessed, there were no significant effect on variables measured such as obstructive sleep apnoea, type 2 diabetes on the effect of IPSS post-bariatric surgery within the follow-up period of 4-6 months.
Conclusion:
Bariatric surgery can have significant improvements on nocturia symptoms in men and women with obesity. This is another means in how bariatric surgery can reduce morbidity and improve quality of life.
