title: [Extracorporeal shockwave lithotripsy in children. Study of the effectiveness and renal consequences in a series of eighteen children].
abstract: 17 children from 18 months to 16 years old were treated by ESWL for calculi of the upper urinary tract using a Sonolith 3000 lithotriptor. 31 calculi (5 to 60 mm) have been treated on 16 renal units and 3 pelvic ureters. The renal parenchyma of all treated kidneys was considered normal on preoperative ultrasound and IVU; 8 patients had a preoperative DMSA. The treatment required 1 to 4 sessions delivering 400 to 3000 shocks per session and 400 to 6000 shocks per treatment at 14 kV. Within three months post treatment, 14 patients (88.23%) were stone free and 3 patients had residual fragments (2 needed further surgical extraction). With a follow up of three months to five years, all patients have a normal blood pressure, serum creatinine and sterile urine. In no instance, IVU or ultrasound revealed a lesion imputable to ESWL. Seven patients had a DMSA six months or more after the last session; 4 of these were normal but the three other patients had a loss of function and an heterogeneous fixation on the treated side. These preliminary results confirm that ESWL is efficient for upper urinary tract calculi destruction in children. However ESWL seems to be susceptible to induce parenchymal damage, detected by DMSA, whose incidence and long term effects particularly on blood pressure need further evaluation.
