Correlation between Nocturia and Sleep: A Questionnaire Based Analysis

PURPOSE: This study evaluated the effectiveness and quality of sleep (QoS) in adult patients with nocturnal lower urinary tract symptoms (LUTS) including nocturia and nocturnal polyuria. MATERIALS AND METHODS: A total of 102 patients with nocturia and daytime LUTS were enrolled in this study. All patients completed a questionnaire that included the International Prostate Symptom Score (IPSS), quality of life score (QoL), overactive bladder questionnaire (OABq), and a sleepiness index. The sleepiness index was measured with the Korean Beck Depression Inventory (K-BDI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Berlin Questionnaire (BQ), and the International Restless Legs Syndrome Study Group (IRLSSG). Statistical analyses included the Student's t-test and chi-square test. Differences were considered significant at a p-value of less than 0.05. RESULTS: Nocturia during sleep was experienced by 68 (66.7%) out of 102 patients. There was no significant association between the nocturia- and the sleep-related scales, but with multiple regression analysis for sex and age, the K-BDI score (p=0.05), IPSS score (p=0.05), and OABq (p=0.02) were significantly higher in patients who woke up to void during sleep. A total of 57 (55.9%) patients diagnosed with overactive bladder with nocturia had severe daytime sleepiness on the ESS questionnaire (p=0.019) and more urgency symptoms on the IPSS questionnaire (p=0.007). CONCLUSIONS: Patients with nocturia had a greater risk of being depressive and felt sleepier during the daytime. LUTS including nocturia and sleep quality closely affected each other. Therefore, clinicians should consider patients' LUTS and sleep problems or QoS as well to provide more satisfying outcomes.

Aneurysmal Dilatation of Corpus Cavernosum as an Unusual Complication of Dorsal Penile Neurectomy / 대한남성과학회지

A 43-year-old man presented painless protruding mass on left side of penile shaft only during erection. 1 year ago he had a dorsal penile neurectomy for the treatment of premature ejaculation at local clinic. A protruding cavernousal aneurysm about 2 cm in diameter was developed 6 months after surgery and confirmed on penile duplex ultrasonography after PDE5 inhibitor ingestion with visual sexual stimulation. We have observed the lesion every month and found there was slight enlargement for the last 3 months without any other symptoms. We performed cavernosoplasty under the genereal anesthesia. There was a round cavernosal aneurysm on the left side of penile mid-shaft about 4cm in diameter after artificial erection with intracavernosal saline injection. We prevented cavernosal protrusion by covering the aneurismal surface with bovine pericardium patch (Supple Peri-Guard(R)). There was no side effect for 6 months postoperatively. This is an unusual type of complication of dorsal penile neurectomy.
