[Urolithiasis in Isreali children (author's transl)]

Sixty-eight children (ages ranging from 5 months to 16 years) with urolithiasis were treated between 1966 and 1979. There were 36 females (53%) and 32 males (47%). Sixteen children (24%) had associated urinary tract infection; 4 out of these (6%) presented with urinary tract malformation. Fifty-five calculi (89%) were found in the upper urinary tract (kidney and ureter); 24 of the chemically studied calculi (80%) were made of calcium salts. In 30 children, metabolic investigations were carried out, leading to the discovery of hypercalciuria in 17 (57%). In one patient, important vesico-ureteral reflux associated with urolithiasis led to renal failure.
