Pediatric Urolithiasis in the 1970s

Abstract

Children (38) presented with urolithiasis between 1970-1977 were studied retrospectively. The sex ratio was 1:1 and the mean age was 9.4 yr. A positive family history was found in 36%. Urinary tract abnormalities predisposing to infective urolithiasis was found in 7 children (18%) but required voiding cystography for detection in 5. Hypercalcemia was found in 3 of 32 (8%), while 28 of the 38 patients (74%) had idiopathic urolithiasis. Idiopathic hypercalciuria was found in 5 of 13 patients (38%) with idiopathic urolithiasis. Investigation of urolithiasis in children should include voiding cystography and measurement of urine Ca, as well as oxalate and uric acid, under home diet conditions.
