TREATMENT OF DISTAL URETERAL STONES IN CHILDREN: SIMILARITIES TO THE AMERICAN UROLOGICAL ASSOCIATION GUIDELINES IN ADULTS

Abstract

Purpose: The American Urological Association (AUA) published clinical guidelines for the treatment of ureteral calculi in adults and note that up to 98% of stones less than 5 mm. in diameter will pass spontaneously. Ureteroscopy and shock wave lithotripsy were acceptable treatment choices for stones less than 10 mm. in diameter in the distal ureter. We reviewed our management of distal ureteral stones in children to see if the AUA Guidelines for adults would apply.Materials and Methods: A total of 14 males and 19 females with a mean age of 12 years (range 0.5 to 17) required hospitalization in the last 6 years for distal ureteral obstruction due to stones. Excretory urography or computerized tomography was performed in all cases, and mean stone size was 4 mm. (range 1 to 15). When stones did not pass spontaneously most patients were treated with ureteroscopic laser lithotripsy.Results: There were 12 (36%) with a mean age of 11 years and a mean stone size of 2 mm. (range 1 to 3) who passed stones spontaneo...
