Nocturnal polyuria syndrome (NPS) denotes nocturnal polyuria (NP) in the absence of identifiable contributory factors. The trajectory of nocturnal urine production (NUP; typically expressed as ml/hour) may be useful in delineating between NP patients with versus without NPS, but changes in absolute urine volume, the directly measured substrate for behavioral and pharmacologic interventions targeting nocturnal urine production, have not been well characterized.
Nocturnal polyuria (NP), the most common etiology of nocturia, can be caused by various medical conditions, including cardiovascular disease, obstructive sleep apnea, renal tubular dysfunction, as well as medications (e.
Nocturnal polyuria (NP), characterized by overproduction of urine at night (greater than 20-33% of total 24-hour urine volume depending on age), is a major contributing factor in most nocturia cases.
A recent update in International Continence Society (ICS) terminology now recognizes nocturnal polyuria (NP) and diurnal polyuria (DP) as related subcategories of "Polyuria (global symptom)".
Compare the circadian trajectory of diuresis between nocturnal polyuria (NP) patients with versus without identifiable contributory comorbidities.
