The most obvious cause is a kidney or systemic disorder, including amyloidosis, [2] polycystic kidney disease, [3] electrolyte imbalance, [4] [5] or some other kidney defect. [2] The major causes of acquired nephrogenic diabetes insipidus that produce clinical symptoms (e.g., polyuria) in the adult are lithium toxicity and high blood calcium.
Dent's disease (or Dent disease) is a rare X-linked recessive inherited condition that affects the proximal renal tubules [1] of the kidney. It is one cause of Fanconi syndrome , and is characterized by tubular proteinuria , excess calcium in the urine , formation of calcium kidney stones , nephrocalcinosis , and chronic kidney failure .
