[Extracorporeal lithotripsy in children].
14 patients of pediatric age with renal and ureteral calculi were treated with extracorporeal shock wave lithotripsy (Piezolith 2300). Three of the 14 patients had bilateral renal calculi. There were nine male and five female patients with an average age of 9.7 years. Most of the calculi were the renal pelvis. four calculi were smaller than 10 mm, 12 were between 10 and 20 mm and one was a partial staghorn calculi. A double "J" stent way placed in two patients, one with an ureterostomy and another with a partial staghorn calculi. The average number of shock waves received for patient was 4275 with an average voltage of 582 bars. Only 2 patients (16.6%) required sedation, six patients (47%) required more than one session of lithotripsy. The results at 3 months showed that 71.4% of the patients were free of stones. Hematuria was present in all the patients, hyperthermia greater than 38 degrees C and renal colic were present in 21.4% of the cases, two patients with retained ureteral calculi were rendered stone free by endoscopic procedures. In conclusion our results are similar to those reported in the world literature. The use of ultrasound for stone localization prevents unnecessary radiation of the children, and finally with the machine employed most of the treatments can be performed without anesthesia.
