Aim To identify short-term effects of extracorporeal shock wave lithotripsy (ESWL) on renal function in children and adolescents with single kidney stones. Methods In a 4-year period 30 children (15 boys and 15 girls) from 10 to 18 years of age were treated for unilateral renal stones with ESWL. Inclusion criteria were: up to 18 years of age, kidney stone (from 4 to 20 mm in diameter) visible on X-ray, first ESWL treatment, unilateral lithotripsy treatment without previous kidney surgery,

Serum enzymes (alkaline phosphatase, lactate dehydrogenase), cystatin C, serum and urine electrolytes (sodium, potassium, chloride), and urine neutrophil gelatinase-associated lipocalin (uNGAL) were tested before, on the first and fifth day after the treatment. Results An increase of alkaline phosphatase and lactate dehydrogenase was statistically significant on day 1 (p<0.05) and values returned to normal on day 5. Serum cystatin C level was also significantly increased during the first four days after ESWL treatment (p<0.05) and returned to baseline on post-treatment day 5. There was a statistically significant difference in the level of uNGAL in urine before and 24 hours after ESWL treatment (p<0.05). Conclusion The ESWL is a safe and curative procedure for the treatment of kidney stones in children and adolescents with no evidence of serious adverse effects on renal function.
