Pediatric Extracorporeal Shockwave Lithotripsy: Its Efficiency at Various Locations in the Upper Tract

Several reports demonstrated the effectiveness of extracorporeal shockwave lithotripsy (SWL) in the management of pediatric upper tract urolithiasis. The majority of these studies used the stone-free rate as the main indicator for treatment success. Efficacy Quotient (EQ) is an important outcome measure because it not only takes into consideration the stone-free rate, but also includes other undesirable outcomes that increase patient morbidity and utilizes hospital resources. Nevertheless, very few studies reported on the EQ of pediatric SWL at various locations in the upper tract.
