Abstract
- Between January 1975 and July 1976 We had the opportunity to treat 3 patients with upper urinary tract calculi. Both the incidence and clinical characteristics of urinary calculi vary greatly from one part of the world to another and from one historical period to the next. Although this variation is seen in adult disease it is even more evident in pediatrics, and recent contributions on the subject from different countries emphasize this wide range. Prior to this century urinary tract calculi in children were endemic and primarily located in the bladder but have been gradually disappearing since World War I. Williams' recent series of 133 cases of childhood calculi describes the majority of stones to be renal in origin, either related to some anatomic defect or idiopathic but with urinary infection, the bulk being made up of calcium phosphate and magnesium ammonium phosphate often times in a matrix of uncalcified material. In this report, all of the 3 cases were upper urinary tract calculi and misdiagnosed initially. No underlying cause was found.
