Ureteroscopy in the management of pediatric urinary tract calculi.
J Endourol. 2005 Mar; 19(2):151-8.JE

Abstract

PURPOSE

To report our experience with ureteroscopy in the treatment of pediatric urinary tract calculi and present a review of the literature.

PATIENTS AND METHODS

Between 1988 and 2003, 52 ureteroscopic procedures were performed in 25 male and 10 female children aged 11 months to 15 years (mean 5.9 years). Using a semirigid 6.8F 43-cm ureteroscope and routine antibiotic prophylaxis, stones were fragmented with a pulsed-dye laser (N = 14; stone size 6-15 mm with a mean of 9.6 mm), electrohydraulic lithotripsy (EHL) (N = 26; stone size 3-20 mm with a mean of 8.4 mm), or a holmium laser (N = 7; stone size 5-15 mm with a mean of 10 mm); removed by basket extraction (N = 5; stone size 5-8 mm with a mean of 7 mm); or both. Stenting or ureteral dilatation was not performed routinely.

RESULTS

With the pulsed-dye laser, there was an overall stone-free rate of 72%. Complications consisted of one ureteral perforation and one stenosis of the intramural portion of a megaureter (14% complication rate). With EHL, the overall stone-free rate was 92%. Complications consisted of one case each of ureteral perforation and incipient urinary retention and five of mild fever (27%). With the holmium laser, the overall stone-free rate was 100%, and there were no complications. Basketing likewise produced a 100% stone-free rate, and there was one complication, a mucosal tear in a patient who also underwent pulsed-dye laser lithotripsy.

CONCLUSION

Ureteroscopy is a safe and effective means of treating the majority of pediatric ureteral calculi, although retreatment rates are higher with multiple stones and in younger children. Dilatation of the vesicoureteral junction is usually not necessary with ureteroscopes <8F, nor is ureteral drainage required after uncomplicated ureteroscopy. The holmium laser is the most effective and safest method of fragmentation regardless of stone composition. Ureteroscopy for this indication should be performed only by an experienced endoscopist.
