[Parathormone and renal excretion in healthy controls and patients with nephrolithiasis (author's transl)].

Idiopathic nephrolithiasis with recurrent ca-oxalat stones are investigated for occult renal dysfunction or for disturbed clearance of PTH. After injection of PTE a significant increase of renal excretion of Na+, K+, Ca2+ and uric acid was observed normalizing within 120 min after injection. Healthy controls showed similar changes, and following PTH the cAMP generating capacity of patients with recurrent stones was in normal range. The turn over rate of PTH was 30-40 min without differences in the collectives studied.
