Long-Term Follow-Up after Extracorporeal Shock Wave Lithotripsy in Children

In 34 children (25 girls and 9 boys), aged 1-14 years, extracorporeal shock wave lithotripsy (ESWL) was performed for renal and ureteral calculi between March 1985 and December 31, 1989. The patients were treated with the HM3-Dornier lithotripter under general anesthesia. Of the 34 children, 24 with an interval of more than 12 months since ESWL were called in for control check up, 17 of them ultimately came. Seven were lost for long-term follow-up as they moved out of the area. The children were free of urinary symptoms and without urinary tract infections. Creatinine was normal and urinalyses were negative in all 17 children. 16/17 children were stone free and had normal blood pressure, 1 patient with a polycystic kidney on the left nontreated side already demonstrated elevated pretreatment blood pressure. Radioisotope examinations with separate clearance tests gave results in the normal range in 14/17 patients. The sonographic findings on the longitudinal and transverse diameter of the treated and untreated kidneys did not show marked differences as they all remain below the 5% limit.

Long-Term Results of Extracorporeal Shock Wave Lithotripsy in Children

Extracorporeal shock wave lithotripsy was performed for treatment of calculi of the upper urinary tract in 73 children. All patients were treated with the standard HM3 Dornier lithotriptor. A total of 138 calculi in 86 renal units was treated, requiring 111 extracorporeal shock wave lithotripsy sessions. After therapy no serious complications were encountered. Six months after treatment 79 per cent of the patients were free of stones and 17 per cent had small residual fragments (less than 3mm.), while extracorporeal shock wave lithotripsy was considered to be unsuccessful in 3 children, although disintegration could be obtained in all patients. During a median followup of 24 months (range 13 to 40 months) growth of residual fragments was noted in 33 per cent of the patients and the recurrence rate was 10 per cent.

Experience with extracorporeal shock wave lithotripsy in children.

In 14 children, aged 2-14 years, extracorporeal shock wave lithotripsy was performed for renal and ureteral calculi. In 12 out of 14 children, including 1 patient with a staghorn calculus, complete stone clearance was achieved within the first 3 months following treatment representing 85%. No undue side effects or complications were encountered in this series.

Initial Experience with Extracorporeal Shock Wave Lithotripsy in Children

The clinical experience is presented of 4 United States centers at which extracorporeal shock wave lithotripsy was used for the treatment of renal calculi in 38 children 12 months to 16 years old. Patient characteristics, treatment specifics and followup data are detailed. Complete fragmentation of calculi was obtained in 97 per cent of those treated, with a 5 per cent complication rate. This experience demonstrates that with proper safeguards, extracorporeal shock wave lithotripsy can be performed safely and effectively in the pediatric population.

Extracorporeal Shock Wave Lithotripsy in Childhood

Extracorporeal shock wave lithotripsy is the treatment of choice for the majority of upper urinary calculi in adults. Technical limitations, including patient size and concerns over post-treatment stone fragment passage, have made the application of extracorporeal shock wave lithotripsy in children less clearly defined. We report the successful application of the Dornier lithotriptor in the management of 18 children (22 kidneys) with upper urinary calculi.
