    Urinary Stone disease may lead to progressive kidney damage. The aim of this study was to evaluate the clinical features and possible risk factors for pediatric urolithiasis.Data belong to 342 children (205 boys, 137 girls) that followed up for the last 10 years was retrospectively reviewed. The mean age of patients was 7.2±5.1 years at presentation. Renal insufficiency was detected in 79 (23.1%) at diagnosis. Of whom 79% had prerenal and 21.1% postrenal renal failure. Stone locations were as follows: 124 patients (36.6%) right sided, 98 (28.7%) left sided and 120 (35.1%) bilateral. Of all, 89.6% of stones were localized in kidney and pelvis renalis. Family history of urolithiasis was found in 25.4% of children. The foremost complaints are abdominal pain (64.3%), irritability (58.2%), dysuria (48.7%) and renal colic (32.4%). Urinalysis revealed leukocyturia in 46.2%, haematuria in 43.6%, proteinuria 32.2% and crystalluria in 18.1% of patients. Urine culture yielded E.coli in 65.4% of patients with urinary tract infection. Stone analysis most frequently showed calciumoxalate stones. The most common encountered metabolic risk factors are hypercalciuria (25.4%) and hypocitraturia (14.0%). In 26.3% of patients there was an additional urinary tract abnormalities. Urolithiasis is important because leading to renal insufficiency. Metablic studies should be performed and additional urinary tract abnormalities should be sought in children with urolithiasis

    (Düzce Üniversitesi, 2009) Bozkurt, Yaşar; Sancaktutar, Ahmet Ali; Yağcı, Sezgin; Kapan, Murat; Murat, Hacı
    Aim: The aim of this study was to evaluate the success rate and factors that effective on stone-free ratio.Materials and methods: Data belong to 146 patients with ureteral stones that treated by ESWL between January 2007 and August 2008, were retrospectively reviewed. Treatment outcome, stone-free and treatment failure ratios and frequency of complications were determined.Results: The mean age and stone diameter of patients were 39 years and 10.3 mm , respectively. Mean of 2.5 séance ESWL was applied at the 4066 shoots. The overall stone-free ratio was 69.2% after 3 weeks of ESWL. No significant difference was found in patients’ age, stone-diameter, amount of shoot and stone-free ratio between lower, mid and upper ureteral stones (P gt;0.05). A significant negative correlation was found between stone diameter and stone-free ratio (r=-0.340, P
