Nocturia (derived from Latin nox, night, and Greek [τα] ούρα, urine), also called nycturia (Greek νυκτουρία), is the need to get up during the night in order to urinate, thus interrupting sleep. Its occurrence is more frequent in the elderly. Nocturia could result simply from too much liquid intake before going to bed, or it could be a symptom of a larger problem, such as chronic renal failure, urinary incontinence, Interstitial Cystitis, diabetes, benign prostatic hyperplasia, Ureteropelvic junction obstruction[1] or prostate cancer.

Historical Perspective

  • Nocturia was defined by International Continence Society (ICS) in 2002, as the need to wake up one or more times at nights to void. [2]
  • Clinical definition of nocturia is awaking from sleep to urinate two or more that two times per night. [3] [4]

Causes by Pathogenesis

Causes of Nocturia
Due to Hormonal imbalance
Due to Vesical problems
Global Polyuria
Nocturanl Polyuria
Sleep disorders
Bladder storage disorders

Causes Due to Hormonal Imbalance

Global Polyuria Nocturnal Polyuria Sleep disorders

Defined as a 24-hour urine volume that exceeds 3 liters per day (or 40 mL per kg). The common causes of global polyuria are

Nocturnal polyuria is defined as an increase in urine production during the night but with a proportional decrease in daytime urine production that results in a normal 24-hour urine volume. Nocturnal polyuria may be due to age-related changes in the secretion and action of arginine vasopressin (AVP). There is a diurnal periodicity in AVP release in young, healthy subjects, with higher AVP plasma levels in the evening contributing to decreased nighttime urine output. The diurnal variation in AVP release is absent in many older people. Compared with the normal patients, nocturia patients have a nocturnal decrease in AVP level. Other causes of nocturnal polyuria include diseases such as

Sleep disorders have been demonstrated to be a frequent cause of nocturia in men younger than 50 years and in women with symptoms of daytime overactive bladder syndrome. Primary sleep disorders may result in nocturia either because of hormonal changes related to sleep-disordered breathing or due to patient misperception of the reason for awakening due to the sleep disturbance but recall this as an awakening to void. e.g.

OSA may also cause nocturnal polyuria by release of atrial natriuretic peptide (ANP).

Causes Due to Vesical Problems

Bladder storage disorder

Reduced bladder capacity or impaired bladder function results in low-volume voids. Most common causes of low-volume bladder voids are

Epidemiology and Demographics

  • The prevalence of nocturia ≥ 1 voids is approximately 69000 per 100,000 men aged ≥ 40 years and 76000 per 100,000 women aged ≥ 40 years in the United States, United Kingdom, and Sweden. [8] [6]
  • The prevalence of nocturia ≥ 2 voids in population aged 20-30 years is approximately 4000 to 18000 per 100,000 women and 2000 to 17000 per 100,000 men. [9]
  • The prevalence of nocturia ≥ 2 voids in population aged 70-80 years is 28000 to 62000 per 100,000 women and 29000 to 59000 per 100,000 men. [9]
  • The prevalence of nocturia ≥ 2 voids in in Canada, Germany, Italy, Sweden, and the United Kingdom is 13000 to 17000 per 100,000 individuals aged < 40 years and 20000 to 21000 per 100,000 middle-aged populations and 35000 to 36000 per 100,000 individuals aged ≥ 60 years. [10]

Risk Factors


There is insufficient evidence to recommend routine screening for nocturia.

Natural History, Complications, and Prognosis


Diagnostic Study of Choice

  • The diagnosis of nocturia is based on the clinical history defined by International Continence Society (ICS) in 2002, which includes wake up at night ≥1 times to void. [20]
  • According to new revised definition in 2017 , nocturia is to wake up to void during the sleep period. [21]
  • Bladder diary should be asked from the patients, including [22]
    • the amount of water intake
    • the time of water intake
    • time and volume of urination
      • the number of urinations during the day
      • the number of nocturia (urination during the sleep),
      • the number of urinations and the amount of urine production during the day
  • Frequency- volume charts can be diagnostic for nocturia. [4]

Other Diagnostic Studies


Medical Therapy


  • Treatment options for nocturia depend on the underlying causes.
  • Behavioral modification includes [22] [4]
  • Pharmacologic medical therapies for nocturia include
    • desmopressin (arginine vasopressin) [22]
      • It decreases urine volume through vasopressin V2 receptors, which leads to increase water reabsorption in renal tubules.
      • It is the preferred drug for the treatment of nocturia due to nocturnal polyuria according to the European Association of Urology (EAU) recommendation. [25]
    • α-blockers
    • antimuscarinics
    • phosphodiesterase type 5 inhibitors
    • Botulinum toxin
