PEDIATRIC STONE DISEASE: AN EVOLVING EXPERIENCE

The majority of patients had no congenital abnormalities. Early diagnosis of urological abnormalities and urinary infection, and appropriate management of neurogenic bladder may have reduced the incidence in those groups. Most stones are calcium based but occur in the absence of metabolic disturbances. More patients presented in the fall, perhaps reflecting the increased concentration of urine in the summer. Half of the patients passed the stones and shock wave lithotripsy was curative in most others. Ureteroscopy, percutaneous nephrostolithotomy and open surgery were rarely required.
