Litotripsia extracorpórea por ondas de choque en niños. A propósito de un caso complicado.

Extracorporeal shock wave lithotripsy is an effective procedure for the treatment of renal and ureteral lithiasis. In pediatrics has become widely accepted by the facility of the procedure, availability of lithotripters and faster discharge from hospital. However, complications in pediatric patients can vary from symptomatic (pain) to a compromise renal function. We present a case of a 15 year old female adolescent with bilateral renal lithiasis which underwent for extracorporeal shock wave lithotripsy session which was complicated by a left renal hematoma, confirmed by renal ultrasonography and computerized tomography scan. Conservative management was established and the hematoma became stabilized. The patient developed hypertension and glomerular filtration rate was decreased on the ipsilateral kidney four weeks after the procedure which had spontaneous resolution. Pediatric extracorporeal shock wave lithotripsy is an effective procedure for the treatment of renal and ureteral calculi; its advantages are easiness, speed and accessibility. A renal hematoma as a complication occurs in less than 1%. Patient monitoring and follow-up identified timely this complication. [ABSTRACT FROM AUTHOR]
