In situ extracorporeal shock wave lithotripsy (ESWL) for the management of primary ureteric calculi in children

A retrospective analysis was done to determine the efficacy of shock wave lithotripsy (SWL) and ureteroscopy in the treatment of paediatric ureteral calculi. We reviewed the records of 67 (35 boys, 32 girls) children (71 ureters) admitted to our clinic for treatment of ureteral calculi during 1990-2005. The initial treatment method was SWL in 80.3% (57 ureters), ureteroscopy in 11.3% (eight ureters) and open surgery in 8.5% (six ureters) of the renal units. The mean age of the patients was 10.67 +/- 4.4(1-16) years. The stone-free rates after SWL for upper, middle and lower ureteral calculi were 74.1, 100 and 75.9%, respectively. Increased stone diameter (P = 0.014) and/or burden (P = 0.002) were found to be significant factors that had an adverse affect on the stone-free rate after SWL while the success rates of SWL were independent of location. Including six patients (seven ureters) with failed SWL, a total of 14 patients (15 renal units) subjected to ureteroscopy for lower ureteral calculi yielded a stone-free rate of 93.3%. Thus, the overall stone-free rates after SWL, ureteroscopy and open surgery were found to be 75.4, 93.3 and 100%, respectively. Depending on the stone burden, SWL might be a good option for initial treatment of most ureteral calculi in children. Ureteroscopy offers a high success rate for lower ureteral calculi, including SWL failures.

Our objective was to determine the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of paediatric ureteral calculous disease. We reviewed the records of 41 (23 boys, 18 girls) paediatric patients admitted to our clinic for the treatment of ureteral calculi between between 1989-2001. Patients' age varied between 4-16 years. The majority of the patients, 38 (92.7%) cases were treated initially with ESWL whereas 3 (7.3%) cases were subjected to ureterolithotomy. The mean age of the patients was found as 12.8+/-3.86 (4-16) years. Most calculi were located at either upper or lower ureter. The mean stone burden was 45.16+/-30.65 mm2 and the mean shock wave number per session and power as 2826.72+/-605.18 and 17.69+/-1.11 kV respectively. Minor complications included skin ecchymosis at the site of entry of shock waves in all cases and renal colic that responded to analgesics and emetics in 3 (7.9%) patients. The overall stone-free rate after ESWL was found to be 81.6%. Two (5.3%) cases have residual fragments that escaped to lower calices after lithotripsy for upper ureteral calculi and are still followed. There were 5 (13.2%) failures who were treated with ureterolitotomy for 1 upper and 1 lower ureteral calculi and with ureteroscopy for the rest. It appears that ESWL is still a good option for the initial treatment of most ureteral calculi in children as it is less invasive than ureteroscopy and has a high success rate as a first-line therapy.
