0 A patient with polyuria, a low urine osmolality, and a high serum osmolality is given
vasopressin, but no change in osmolality is noted. Which type of diabetic insipidus does she have?
Nephrogenic. Vassopressin will not help because the distal renal tubules are refractory to antidiuretic
hormone. In central DI, the pathology involves a problem with the production ofADH in the posterior
pituitary. An increase in urine osmolality of at least 50% will occur with vasopressin administration if the
problem is central DI.
