[Advances in clinical study of nocturia].
Nocturia is one of the most common reasons for interrupted sleep in general adult population. The condition affects both men and women, with an incidence that increases dramatically with age. Nocturia has a negative impact on quality of life, affecting both morbidity and mortality. International Continence Society (ICS) issued a report of terminology standardization in 2002, in which nocturia is defined as waking during the night at least once to urinate. Nocturia is a common complaint in elderly population. Although most cases of nocturia are assumed to be caused by urologic problems, the interacting effects of aging and sleep on renal and urinary function, in fact, cause nocturia in the elderly. Effective diagnosis of the condition is dependent on a clear understanding of its underlying etiology. Multiple factors may cause nocturia, such as behavioral or environmental factors and pathologic conditions. In general, the causes of nocturia fall into three categories: diurnal polyuria, nocturnal polyuria, and low bladder capacity. Careful evaluation of medications and underlying medical conditions is essential for the proper management of nocturia. A voiding diary is necessary to diagnose the syndrome of nocturnal polyuria, which is a common cause of nocturia. Addressing any underlying conditions that contribute to nocturia is the first step in treating the condition. Lifestyle and behavioral changes may provide benefit in some individuals, but for many cases, pharmacotherapy is the best option. Antimuscarinic agents are first-line therapies for overactive bladder and are often used in the management of nocturia. Current treatment options also include desmopressin, a synthetic analog of arginine vasopressin, which can increase urinary osmolality and decrease total urinary volume. The desmopressin therefore increases the length of time until the first nocturnal void and decreases the number of nocturnal voids, the NUV voided, and the percentage of urine voided at night.
