Liu SYW, Yee CH, Chiu PKF, et al. - Researchers undertook this prospective observational study to assess whether bariatric surgery is effective for attenuating the prevalence as well as the severity of male lower urinary tract symptoms (LUTS) in obese patients. Consecutive morbidly obese men receiving bariatric surgery were included. LUTS prior to and at 1–3 years following surgery was evaluated employing the International Prostate Symptom Score. A significant BMI decrease from 39.1 ± 5.2 kg/m² preoperatively to 30.1 ± 4.8 kg/m² at 1 year and 31.5 ± 4.9 kg/m² at 3 years was evident, post-surgery. There was also an attenuation in the prevalence of moderate to severe LUTS, from 35.0% preoperatively to 21.8% at 1 year and 30.4% at 3 years. Overall, findings demonstrated the effectiveness as well as the durability of bariatric surgery as an intervention for alleviating the prevalence and severity of LUTS in morbidly obese men for up to 3 years.
