these data indicate that pd impairs ca reabsorption in tubular segments before but not within the distal convoluted tubule , so that hypercalciuria is ultimately a result of decreased ca transport either in the terminal nephron or in deeper nephrons where po ( 4 ) infusion stimulates ca transport independent of parathyroid hormone or changes in the filtered load of ca .
