Q

Explain the difference of cranial and nephrogenic DI and how to differentiate?

A 
Nephrogenic = kidneys not responsive to ADH.
Cranial = insufficiency of ADH.

Desmopressin stimualtion test: Patients are given desmopressin subcutaneously. Serum osmolality, urine osmolality, and urine volumes are measured hourly over the next 4 hours.
- Central DI: >50% increase in urine osmolality following desmopressin (more concentrated).
= Nephrogenic DI: no or <50% increase in urine osmolality following desmopressin and still high urine output.
