Effect of Continuous Positive Airway Pressure on Overactive Bladder Symptoms in Patients with Obstructive Sleep Apnea...

To evaluate overactive bladder (OAB) in male and female patients with moderate or severe obstructive sleep apnea syndrome (OSAS) and to investigate the impact of three months of continuous positive airway pressure (CPAP) therapy on the symptoms of OAB.

Twenty-eight female and 45 male patients with moderate and severe OSAS whose obstructive sleep apnea (OSA) severity was evaluated according to the apnea-hypopnea index were included in the study. Patients' voiding symptoms were evaluated using the validated Turkish translations of overactive bladder symptom scores (OAB-V8) and the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) at OSAS diagnosis and at 3-months after the CPAP therapy.

Patients with moderate and severe OSAS were more likely to have OAB than the average population, and CPAP therapy improved the symptoms of OAB in both male and female patients. In addition, a positive association was observed between OSA severity and OAB-V8 and ICIQ-SF in female patients and between OSA severity and OAB-V8 in male patients.

Our findings suggest that CPAP therapy improves the clinical symptoms of OAB. Thus, unnecessary medical or interventional treatment of OAB can be avoided in such patients.
