Noninvasive Tx common for stone disease.

SAN FRANCISCO -- Children with pediatric stone disease require invasive procedures infrequently and have metabolic abnormalities a minority of the time, Kevan M. Sternberg, M.D., reported in a poster presentation at the annual meeting of the American Academy of Pediatrics.

In a study of 123 children with 158 stones, Dr. Sternberg of the Women and Children's Hospital of Buffalo (N.Y.), reported that 46% passed their stones spontaneously and 28% underwent extracorporeal shock-wave lithotripsy.

Only 8% of the children had ureteroscopy, 3% had percutaneous nephrostolithotomy, and 3% had open surgery.

The investigators found hypercalciuria in 12% of the children, hyperoxaluria in 2%, and cystinuria in 2%.

Of the 59 stones whose composition was analyzed, 52 (88%) were calcium based, 4 (7%) were struvite, and 3 (5%) were cysteine.

Fully 41% of the children presented in the fall, while only 21% presented in the summer, 22% in the spring, and 13% in the winter. The investigators suggested that the predominance of fall presentations may have been caused by relative dehydration during the preceding summer.
