Critical evaluation of the overactive bladder and urgency urinary incontinence association with obstructive sleep apnea syndrome in a relatively young adult male population

AimsTo evaluate the prevalence of Overactive Bladder (OAB) and Urgency Urinary Incontinence (UUI) in males with Obstructive Sleep Apnea Syndrome (OSAS) using the OSAS grading system. MethodsA total of 194 patients who underwent Polysomnography (PSG) were included in our prospective cross sectional study. Patients were divided into four groups according to Apnea-Hypopnea Index (AHI). Group 1, 35 patients with normal AHI (<5) as a control group; Group 2, 47 patients with mild OSAS (AHI 5 and <15); Group 3, 51 patients with moderate OSAS (AHI 15 and <30); Group 4, 61 patients with severe OSAS (AHI 30). Over Active Bladder (OAB-V8), ICIQ-SF, and IPSS questionnaires were filled out for all patients. Prevalence of OAB, UUI, nocturia, and scores of OAB-V8, ICIQ-SF, IPSS were compared between the study groups. The statistical analysis was adjusted by the demographics of age and BMI. ResultsThe mean age was 44.611.2 years, and the mean BMI was 29.9 +/- 4.9 within the whole study group, and both were statistically different between the groups. The scores of OAB-V8 (P=0.298), ICIQ-SF (P=0.392), IPSS total, IPSS storage, and IPSS voiding (P=0.268, P=0.380, P=0.167, respectively), the prevalence of OAB (P=0.078), UUI (P=0.423), and nocturia (P=0.096) were not statistically different between the study groups. ConclusionsOur findings demonstrated that there is no increase in prevalence of OAB and UUI in relatively young adult male with OSAS. Furthermore, analysis revealed that the higher OSAS grade does not mean the higher prevalence of OAB.
