Nocturia has a prevalence of 63% in men over the age of 65, and the prevalence of OSA is near 70%. Despite these high percentages, at the VA Boston Healthcare System, only 4% of patients carry a concomitant ICD-9 code for both nocturia and OSA, suggesting an under diagnosis of sleep disorders within the urologic patient population. Given this, we sought to determine if men presenting to a urology clinic with nocturia and/or voiding complaints were also more likely to be at risk for an unrecognized sleep disorder. METHODS A case-control study was conducted on all patients who presented to the VA Boston Healthcare System urology clinic between August 2012 and January 2013. As part of routine evaluation, all patients over age 50 were administered the International Prostate Symptom Score (IPSS) and Berlin sleep questionnaires at the time of clinic check in.Patients completed the questionnaires voluntarily while in the waiting room and the responses were addressed during the clinical visit. RESULTS A total of 633 male patients completed the questionnaires. Of those, 65% (n=410) were found to have nocturia (> 2 voids/night). Of the patients with nocturia, 55% had a positive response on the Berlin questionnaire, suggesting an underlying presence of a sleep disorder. Having nocturia increased the probability of a positive Berlin score (OR 2.09, p<0.01). However, we did not find a significant association between amount of nocturia and Berlin score. Additionally, patients with a positive Berlin response had a higher mean bother score than those with a negative Berlin response (p<0.0001) Not surprisingly, patients with a positive Berlin score had a higher BMI when compared to those with a negative Berlin score (31.7 vs 26.6, p<0.001). CONCLUSIONS Published studies postulate that higher circulating levels of ANP are observed in patients with OSA, leading to polyuria and nocturia. The findings of our study suggest that indeed, nocturia is found in patients at high risk for sleep disorders, an association that has not been significantly explored. OSA is associated with an overall increase in morbidity and poorer patient outcomes and life expectancy, of which nocturia may be the first/most bothersome, indicator. For patients refractory to standard urologic approaches to lower urinary tract symptoms, further investigation into other etiologies of nocturia, such as undiagnosed sleep disorders, is important and referral for evaluation may be prudent. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e151 Peer Review Report Advertisement Copyright & Permissions© 2014MetricsAuthor Information Arun Rai More articles by this author Nannan Thirumavalavan More articles by this author Lori Lerner More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
