How is nocturnal polyuria calculated?

Nocturnal polyuria occurs when urine is overproduced at night while 24-hour urine production volume remains normal. The proportion of urine produced at night can be quantified using the nocturnal polyuria index (NPi), which is calculated as the nocturnal urine volume (NUV) divided by 24-hour urine volume.

What is nocturnal polyuria?

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.

What is the role of antidiuretic treatment in the treatment of nocturia?

Antidiuretic treatment is warranted for patients with nocturia due to NP because, in many patients, it treats the underlying cause (ie, insufficient secretion of antidiuretic hormone arginine vasopressin) that leads to overproduction of urine at night and has been shown to provide statistically significant reductions in nocturnal voids.
