OBJECTIVES: To conduct a prospective study to determine the causes of @entity2183 in @entity1 . METHODS: The study included 41 male @entity1 (mean age 72.5 years) bothered by @entity2183 (two or more micturitions per night). Eleven asymptomatic young @entity1 (mean age 28.4 years) were enrolled as a control group. All completed a 3-day voiding diary. Daytime and nighttime urine samples were collected to determine osmolality and @entity1372 and @entity972 levels. Urodynamic studies were performed for all @entity1 with @entity2183 to evaluate for @entity1876 using the International Continence Society definition. Polysomnography was performed on selected @entity1 to detect sleep @entity386 . RESULTS: The average nighttime voiding frequency was 3.9 in the @entity1 with @entity2183 . Nocturnal @entity2011 (NP) was found in 34 (82.9%) of 41 @entity1 . In these @entity1 , the nighttime urinary @entity1372 excretion was significantly greater than the daytime excretion, with lower nighttime urine osmolality. In contrast, nighttime and daytime @entity1372 excretion was not significantly different in @entity1 without NP, and greater nighttime urine osmolality was noted in the @entity1 without NP and the control group. Of the 41 @entity1 , 24 (58.5%) had a small nocturnal bladder capacity, with detrusor overactivity in 14 of 24 @entity1 . Eighteen @entity1 (43.9%) had both NP and a small nocturnal bladder capacity. Another 18 @entity1 had @entity1876 and NP. Two @entity1 had sleep @entity386 . CONCLUSIONS: Our observations have shown that a significant contributor to male @entity2183 is NP, which results from a disordered diurnal rhythm of @entity1372 excretion and other unknown factors causing nocturnal urinary dilution. However, male @entity2183 can also be secondary to a combination of factors. Detailed workup is necessary to elucidate all causes.
