SAN DIEGO—Bariatric surgery can rapidly and significantly improve storage phase lower urinary tract symptoms (LUTS) in obese men, data presented at the American Urological Association’s 2016 annual meeting suggest.

Asnat Groutz, MD, and colleagues at Tel Aviv Sourasky Medical Center in Israel, prospectively studied 55 obese men who underwent laparoscopic sleeve gastrectomy. Of these, 53 completed all pre- and postoperative questionnaires. Their mean body mass index (BMI) before and 3 months after surgery was 42.8 and 31.3 kg/m2, respectively. Preoperatively, 41 men (77%) had some degree of LUTS, and 39 (74%) were sexually active. Postoperatively, total International Prostate Symptom Score (IPSS) decreased significantly from 5.5 to 2.7, but this change was due to improvement in storage phase LUTS, measured by questions 2 (frequency), 4 (urgency), and 7 (nocturia) of the IPSS questionnaire, Dr. Groutz reported. The frequency score decreased from 1.39 preoperatively to 0.7 postoperatively. The urgency score decreased from 0.78 to 0.2. The nocturia score decreased from 1.4 to 0.55.

The patients also experienced significant improvement in some International Index of Erectile Function domain scores. The mean erectile function score increased from 22.7 to 26.1, the mean intercourse satisfaction score increased from 9.5 to 11.5, and overall satisfaction score rose from 7.9 to 8.9.
