RT Journal Article SR Electronic T1 The relationship between obstructive sleep apnea syndrome and two common urological disorders JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P3829 VO 40 IS Suppl 56 A1 Soner Coban A1 Ege Gulec Balbay A1 Kamil Cam A1 Ali Kayikci A1 Oner Balbay YR 2012 UL http://erj.ersjournals.com/content/40/Suppl_56/P3829.abstract AB Erectile dysfunction (ED) and Lower Urinary Tract Symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) usually occur in older men. The aim was to investigate the relationship between Obstructive Sleep Apnea Syndrome (OSAS) and two urological common disorders.Between January 2007 and April 2010, the men over the age of 50 admitted to the outpatient department of pulmonary diseases with suspected OSAS were selected. All patients had polysomniography analysis. A total of 29 patients having moderate and severe OSAS with apnea-hypopnea index (AHI)=15-30 (11 patients) and AHI>30 (18 patients), respectively were included in the first group.21 patients with AHI<5 constituted the control group. Voiding symptoms were evaluated by using International Prostate Symptom Score (IPSS) and uroflowmetry. ED was investigated by administering International Index of Erectile Function (IIEF).Both groups were comparable with regard to age, PSA, prostate volume, and prostate size by digital rectal examination, IPSS values and uroflovmetry results. On the other hand, nocturia and IIEF results were remarkably different between two groups. The average number of nocturia was 1.47, and the mean score of IIEF was 15.48 in patients with OSAS. Those were 0.88 and 19.90 in the control group, respectively (p <0.05).In this study, IPSS and uroflovmetry values showed no difference between patients with and without OSAS. On the other hand, nocturia and IIEF results were both remarkably different in OSAS patients. As a result, OSAS was shown to be associated with nocturia and ED. Therefore, the patients with complaint of either nocturia or ED should be investigated for OSAS.
