Objectives:
To analyze the efficacy and complication rates of extracorporeal shock wave lithotripsy in the paediatric age group.
Patients And Methods:
From 1989 to 2000, 29 children (mean age 8 years, range 1-14) underwent ESWL for urinary calculi at our institution. A total of forty-four ESWL sessions were performed in 36 calculi and a previous double pigtail stent was inserted in 11 patients. Intravenous anesthesia was used in the vast majority of cases.
Results:
Complete removal of all stone fragments was achieved in 24 (66.7%) renal units after a first session, 6 (16.7%) after a second session. The rest of the patients became stone-free after 3 sessions in 3 patients, open lithotomy in 1 patient and ureteroscopy in another patient. In one case a watchful waiting was decided after the failure of the first session of ESWL. Mean hospital stay was 3.2 days (range 1-11) for each session. Complications appeared in 10 patients: 4 had renal colic, 3 haematuria, 2 fever and 1 subcutaneous hematoma.
Conclusions:
ESWL is a safe and effective treatment for paediatric urolithiasis so it should be considered the first-line treatment.
