Associated Factors for Immediate Success Rate and Stone-Free Rate of Pediatric Extracorporeal Shock Wave Lithotripsy (ESWL) in Cipto Mangunkusumo Hospital: An 8-year Single Center Experience

Extracorporeal shockwave lithotripsy (ESWL) is still considered as the first favorable therapeutic option for urinary stone disease with acceptable effectivity. However, factors associated with favorable outcome has not widely been studied due to the small number of urinary stone prevalence in pediatrics. This study aims to evaluate the factors associated with immediate success and stone-free rate of pediatric ESWL in our center. We provide our data regarding all pediatrics patients <18 years old diagnosed with urinary stone dated from January 2008 until August 2015 were retrospectively analyzed. Patient’s characteristics including age, gender, BMI, stone location, stone length, stone burden, stone opacity, and number of ESWL sessions were gathered from the medical record. Nutritional status was determined according to the Centers for Disease Control and Prevention (CDC) BMI curve. Rate of immediate success and 3-months stone free status were regarded as the main outcome and was recorded for further analysis of each associated factor.
