Long-term treatment of hypercalciuria with thiazides, sodium or potassium cellulose phosphate, separately or in combination.

Urinary supersaturation in respect to brushite or calcium oxalate represents the main pathogenic factor in stone formation. Of the patients with calcium oxalate stones 30 to 40% present with hypercalciuria. Herein we determine and compare the effects and side effects in the treatment of hypercalciuria with sodium cellulose phosphate or Campanyl, a potassium versus calcium ion exchanger, and thiazides alone or in combination with an ion exchanger.
