[Dietary and drug treatments of calcium nephrolithiasis (author's transl)].
Dietary and drug treatments of calcium nephrolithiasis depend mainly on the mineral composition of renal stones: calcium oxalate, phosphate or mixed stones. The association with an hypercalciuria is an important factor which must be taken into account because oxalates and phosphates precipitate as calcium crystals in case of urinnary oversaturation. Despite many therapies have been proposed, their efficiency seems to be rather small when they are used alone. Usually, it is necessary to act on several factors with a combination of therapeutic methods. Absorptive hypercalciuria are improved with both low calcium diets and inhibitors of calcium absorption. In renal hypercalciuria, the treatment is based on the administration of thiazide diuretics which enhance calcium renal tubular reabsorption. The other therapeutic methods depend on the nature of renal stones: urinary acidification for calcium phosphate; administration of succinimide, oral phosphate or organic phosphonates for calcium oxalate stones; association with purine biosynthesis inhibitors in case of the presence of urates in renal calculi.
