BACKGROUND: The reported prevalence rates and etiologies of acute kidney injury (AKI) are quite variable in different regions of the world. The current study was planned to determine the etiology, clinical profile, and short-term outcome of pediatric AKI at our hospital. METHODS: A prospective, observational study was carried out from April 2014 to March 2015. All pediatric patients (1 month to ≤15 years) diagnosed as AKI using modified pRIFLE criteria were studied and followed for 3 months to document short-term outcome...

The goal of this study was to investigate metabolic risk factors in pediatric stone formers in an emerging economy. A prospective, data collection enrolled 250 children age <1-15 years at our center. Risk factors were evaluated by gender and in age groups <1-5, 6-10 and 11-15 years. Patients were evaluated for demographics, blood and 24 h urine for calcium, magnesium, phosphate, uric acid, electrolytes and additional protein, citrate, ammonia and oxalate in urine. All reported values were two sided and statistical significance was considered at p value ≤0...

The Objective of this study is to analyze the difference in renal stone composition between Uyghur and Han children with urolithiasis in China and possible reasons. From May 2011 to September 2013, we analyzed the stone compositions of 274 Chinese children with urolithiasis, including 151 Uyghur children from Xinjiang Province and 123 Han children from Guangdong Province. All the stone components were determined by Infrared spectroscopy and the main components were recorded. We also evaluated the data, including age, gender and geographic region of the patients...

PURPOSE: Treatment of pediatric urolithiasis is still on debate. This study was designed to evaluate the safety and efficacy of laparoscopic pyelolithotomy in five children less than two years old. MATERIALS AND METHODS: Five children (less than two years old) with large kidney stones underwent laparoscopic pyelolithotomy. All patients underwent laparoscopic pyelolithotomy via a transperitoneal approach. After medial mobilization of colon and once renal pelvis and ureteropelvic junction were exposed, a longitudinal or circular incision was made on the renal pelvis, depending on the location and shape of the stone...

BACKGROUND: Urolithiasis (UL) is a common problem in pediatric nephrology practice. About 9-23% of all pediatric UL cases consist of patients under 1 years old. The aim of the present study was to determine etiologic causes, clinical features and short term prognosis of urolithiasis in the first two years of life. METHODS: Two-hundred children between 0-2 years of age (mean age 10.3±6.1 months) with urolithiasis were included to the study. All children were completely evaluated for urolithiasis etiology...

BACKGROUND: The illegal use of melamine in powdered baby formula resulted in a widespread outbreak of melamine-associated pediatric urolithiasis and kidney damage in China in 2008. We conducted this study because more needs to be known about the long-term effects of melamine-associated urolithiasis and kidney damage. OBJECTIVES: To determine the prognosis and long-term implications of chronic kidney damage in children with urolithiasis resulting from melamine consumption...

OBJECTIVE: Pediatric stone disease is a significant health issue which has increased in incidence because of lifestyle changes, dietary habits, and obesity. The incidence of urolithiasis among pediatric age groups varies according to region and is high in Turkey. The management of stone disease in children has improved dramatically over the last two decades. The high success rate of percutaneous nephrolithotomy (PNL) have led modern researchers to suggest that it be used as a first-line treatment of kidney stones greater than 2 cm in size...

OBJECTIVE: To identify longitudinal trends of economic impact and resource utilization for management of pediatric urolithiasis using national databases. METHODS: We analyzed the 2006-2012 Nationwide Emergency Department Sample and Nationwide Inpatient Sample. We used ICD-9 (International Classification of Diseases) codes to identify patients (≤18 years) diagnosed with urolithiasis. Diagnostic imaging and surgeries were identified using ICD-9 and Current Procedural Technology codes...

AIM: The incidence of pediatric urolithiasis has increased over the last century because of dietary changes, metabolic abnormalities, climate change, and genitourinary abnormalities. Data on pediatric urolithiasis in non-endemic countries are limited. The aim of this study was to evaluate the clinical findings and metabolic etiology of urolithiasis in Korean children. MATERIAL AND METHODS: The medical records of 73 Korean children who were newly diagnosed with urolithiasis from January 2010 to December 2013 were retrospectively analyzed...

PURPOSE: To present a combining pyelolithotomy and endoscopy, an alternative approach for treating staghorn calculi in children. MATERIALS AND METHODS: We treated 1414 children (age, 10 months to 17 years) with urolithiasis between 2009 and 2013 in the Pediatric Surgery Department and in the Pediatrics and Nephrology Department, Military Institute of Medicine in Warsaw. Most patients were treated conservatively. In 162 cases, an extracorporeal shockwave lithotripsy (SWL) procedure was needed...

INTRODUCTION: The aim of this review was to identify trends and developments in basic research, epidemiology, diagnosis, conservative and surgical management of urinary stone disease, and to demonstrate the evolution of urolithiasis management in the new millennium. EVIDENCE ACQUISITION: We performed a literature search on Medline according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement up to December 2015 using the following key words: urolithiasis prevalence, recurrent urinary stone, metabolic syndrome and urolithiasis, urinary stone/urolithiasis metabolic evaluation, shockwave lithotripsy, ureterorenoscopy, percutaneous nephrolithotomy/nephrolitholapaxy...

INTRODUCTION: Pediatric urolithiasis has become more prevalent in recent decades, with high recurrence rates and considerable morbidity. Most children with idiopathic urolithiasis have an underlying metabolic abnormality and proper research provides therapeutic interventions to reduce the formation of new stones and its complications. OBJECTIVE: To identify demographic and clinical characteristics of pediatric urolithiasis, etiology, treatment management, disease recurrence and patient outcomes in a tertiary care pediatric hospital...

PURPOSE: Shock wave lithotripsy has been commonly used to treat children with renal and ureteral calculi but recently ureteroscopy has been used more frequently. We examined postoperative outcomes from these 2 modalities in children. MATERIALS AND METHODS: We reviewed linked inpatient, ambulatory surgery and emergency department data from 2007 to 2010 for 5 states to identify pediatric admissions for renal/ureteral calculi treated with shock wave lithotripsy or ureteroscopy...

PURPOSE: The increasing incidence of pediatric nephrolithiasis is a growing concern and its association with obesity continues to be an area of debate. We present data on urine chemistries of overweight/obese children compared to those with a normal body mass index and history of urolithiasis treated at a single institution in the United States, and assess risk factors. MATERIALS AND METHODS: We retrospectively identified 110 stone forming patients who underwent 24-hour urine collection and stratified them according to the Centers for Disease Control and Prevention definitions of overweight/obese (body mass index above 85th/95th percentile)...

Polymorphisms in the vitamin D receptor (VDR) gene have recently been reported to be associated with urinary calculi in pediatric and adult cases, but no studies have looked at the youngest period of life. The purpose of this study was to investigate the role of VDR gene polymorphisms in infantile urolithiasis in a Turkish population. We compared a study group of 104 infants (55 girls and 49 boys, mean age 6.94 ± 3.81 months) with a control group of 96 infants (51 girls and 45 boys, mean age 7.51 ± 3...
