| Background and Aim: Renal stone or urolithiasis is one of the most important and common problems in pediatric field. The prevalence of renal stone is 1.7-4.1% in girls and 4-9% in boys. The incidence of renal stone in pediatric group is 1/1000–1/7600 hospital admission. The aim of this study is to evaluate the prevalence of urolithiasis in patients admitted in Mofid children's hospital. Material and Methods: This is a descriptive study conducted between 2003-2007 on all patients admitted in Mofid Children's Hospital. Children whose ultrasonography reported renal stone were included. The laboratory tests of serum creatinine, venous blood gas, serum calcium, phosphate and uric acid and the urinary levels of creatinine, calcium, phosphate, uric acid, magnesium, sodium, cystine, citrate and oxalate were achieved. The demographic data and the results of ultrasonography and laboratory data were gathered and analyzed by t-test, Fisher's exact test, regression analysis and ANOVA test, when appropriate. Results: The prevalence of renal stone was 17% and the most common etiology for renal stone was hypercalciuria. Hematuria was the most common clinical presentation of renal stone (24%) in study group. There wasn’t any previous history of renal stone in 87.6% of our patients. Our patients showed renal stone in 95.4% and ureteral stone in 4.6%. In 32.2% of the patients ultrasound showed hydronephrosis and in 19.8% renal stone was accompanied with urinary tract infection. The main predisposing factor for renal stone in our study was hypercalciuria (73.5%). We also found a significant correlation between the stone size and urinary levels of calcium, sodium, uric acid, protein, creatinine and specific gravity and serum bicarbonate (p-value <0.000, 0.001, 0.002, 0.002, 0.007, 0.000 and 0.000, respectively). Conclusion: We concluded that renal stone is common in pediatric in patients and the main predisposing factor for renal stone is hypercalciuria. |
