Frequency of overactive bladder (OAB) and the factors affecting it in patients with obstructive sleep apnea syndrome (OSAS).

To investigate the prevalence of overactive bladder (OAB) in patients with obstructive sleep apnea syndrome (OSAS) and the factors affecting it. A total of 255 patients were included in this prospectively designed study. Among all patients, 166 were male, 89 were female; 213 patients were married and 42 were single. All patients underwent polysomnography. All patients completed the OAB-V8 form. OSAS was diagnosed via polysomnography. OAB was diagnosed via OABV8. The participants were evaluated as patients with and without OAB and those with and without OSAS. SPSS for Windows version 18.0 software was used for the statistical analysis and the level of significance was set at The prevalence of OAB was high among the OSAS patients (66.3%, OAB is seen at a high rate in OSAS patients. Hypoxia is the main basis for both diseases and probably it is the common pathway. AHI, WASO, age, and marital status can provide valuable information to physicians for predicting OAB.
