Definition CSP polyuric disorder characterized by normal rates of renal filtration and solute excretion, but a persistent hypotonic urine due to the failure of renal tubules to respond to antidiuretic hormones, such as vasopressin, to reduce urine volume; tubular insensitivity to vasopressin can result from genetic defects, diseases, drug effects, or may occur with pregnancy.

Nephrogenic Diabetes Insipidus

In nephrogenic diabetes insipidus, the kidneys produce a large volume of dilute urine because the kidney tubules fail to respond to vasopressin antidiuretic hormone and are unable to reabsorb filtered water back into the body. Often nephrogenic diabetes insipidus is hereditary, but it can be caused by drugs or disorders that affect the kidneys. To treat nephrogenic diabetes insipidus, people restrict salt in their diet and sometimes take drugs to reduce the amount of urine excreted. See also Introduction to Disorders of Kidney Tubules. Both diabetes insipidus and the better-known type of diabetes, diabetes mellitus , result in the excretion of large volumes of urine. Otherwise, the two types of diabetes are very different. In nephrogenic diabetes insipidus, the kidneys do not respond to vasopressin antidiuretic hormone , so they continue to excrete a large amount of dilute urine.

Nephrogenic diabetes insipidus NDI is a form of diabetes insipidus primarily due to pathology of the kidney. This is in contrast to central or neurogenic diabetes insipidus , which is caused by insufficient levels of antidiuretic hormone ADH, also called vasopressin. Nephrogenic diabetes insipidus is caused by an improper response of the kidney to ADH, leading to a decrease in the ability of the kidney to concentrate the urine by removing free water. The clinical manifestation is similar to neurogenic diabetes insipidus, presenting with polydipsia excessive thirst and polyuria excretion of a large amount of dilute urine. Dehydration is common, and incontinence can occur secondary to chronic bladder distension. As pituitary function is normal, ADH levels are likely to be abnormal or raised. Polyuria will continue as long as the patient is able to drink.

NCBI Bookshelf. Hereditary nephrogenic diabetes insipidus NDI is characterized by inability to concentrate the urine, which results in polyuria excessive urine production and polydipsia excessive thirst. Affected untreated infants usually have poor feeding and failure to thrive, and rapid onset of severe dehydration with illness, hot environment, or the withholding of water. Short stature and secondary dilatation of the ureters and bladder from the high urine volume is common in untreated individuals. The diagnosis of hereditary NDI is established in a male proband with NDI by identification of a hemizygous pathogenic variant in AVPR2 or identification of a compound heterozygous or homozygous pathogenic variant in AQP2 by molecular genetic testing.
