Introduction.  Diabetes is a common risk factor for overactive bladder (OAB) syndrome and erectile dysfunction (ED).

Aim.  The study evaluated the risk factors of OAB and association of OAB and ED in type 2 diabetic men.

Methods.  The diagnosis of ED and OAB was based on a self-administered questionnaire containing Sexual Health Inventory for Men (SHIM) and OAB symptom score (OABSS, 0–15, indicating increasing severity of symptoms), respectively.

Main Outcome Measures.  The clinical variables and diabetes-associated complications, including ED, which are risk factors for OAB, were evaluated.

Results.  Of 453 consecutive subjects attending outpatient diabetic clinic with a mean age of 60.6 years, 25.4%, 10.2%, 81.9%, and 28.3% reported having OAB, OAB wet, ED, and severe ED, respectively. The OABSS is inversely associated with SHIM (correlation coefficient—0.275). The patients with OAB have significantly lower SHIM score, testosterone level, and serum albumin level, have more proportion of severe ED, were older, and have longer duration of diabetes mellitus (DM). After adjustment for age and duration of DM, the presence of severe ED was associated with OAB (odds ratio [OR] = 1.58), and severe ED (OR = 2.36), SHIM score (OR = 0.92), and serum albumin level (OR = 0.24) were risk factors for OAB wet (patients with urgency incontinence, once a week or more). The OR of ED in patients with OAB or OAB wet compared with no OAB was 1.82, and 3.61, respectively. Among the OAB components, urgency incontinence has the strongest impact on ED (OR = 4.06), followed by nocturia, urgency, and frequency. About 15.1% (N = 68) without OAB and ED are younger and have shorter DM duration, lower systolic BP, and higher serum albumin level after multivariate analysis compared with patients with OAB or ED.

Conclusion.  The presence of severe ED was significantly associated with OAB, especially OAB wet. The presence of OAB wet increased the risk and severity of ED.
