Abstract |
Nephrogenic diabetes insipidus is a disorder characterized by polydipsia and polyuria resulting
from failure of the renal tubules and collecting ducts to respond to antidiuretic hormone despite
elevated blood levels of antidiuretic hormone.
We experienced a case of nephrogenic diabetes insipidus in 13 months-old girl probably secondary
to vesicoureteral reflux grade IV.
The clinical manifestations were extreme thirst, polydipsia and polyuria. Family history was
nonspecific and laboratory findings revealed urinary concentration defect by water deprivation test
and pitressin test. But urinalysis revealed normal specific gravity.
Vesicoureteral reflux was corrected by ureteroneocystostomy.
In conclusion, when patient complaints of polydipsia and polyuria, water deprivation test and
pitressin test are mandatory even urinary specific gravity is within normal limit. |
