Effects of bariatric surgery on male lower urinary tract symptoms and sexual function

Aim To investigate the effect of bariatric surgery on male lower urinary tract symptoms (LUTS) and sexual function. Methods Fifty‐five consecutive obese men who underwent a laparoscopic sleeve gastrectomy were prospectively enrolled. Two validated questionnaires, the International Prostate Symptoms Score (IPSS) and the International Index of Erectile Function (IIEF) were used to assess LUTS and sexual function, before and 3 months after surgery. Fifty‐three men (mean age 39 ± 12.5 years) completed all pre and postoperative questionnaires. Mean body mass index (BMI) before and 3 months after surgery was 42.8 ± 5.3 and 31.3 ± 5.4 kg/m2; respectively. Results Preoperatively, 41 (77%) men (mean age 40 ± 12.9, mean BMI 42.2 ± 5 kg/m2) had some degree of LUTS and 39 (74%) men (mean age 40.7 ± 12.4, mean BMI 42.8 ± 5.6 kg/m2) were sexually active. Postoperatively, the total IPSS score decreased significantly (5.5 ± 4.4 vs. 2.7 ± 2.6; P
