Methods The urinary system of totally 5337 children were examined with high frequency convex ultrasound probe,the characteristics of the images were analysed. CT plain scan method was used when ultrasound result was in difficulty. Results There were 360 cases with calculus in the 5337 children. In the 360 cases, unilateral calculus was in 92 cases, bilateral calculus in 48, bladder stone in 3, urethra stone in 1, kidney calcium deposition in 2, suspicion stone in 214 cases, urinary obstruction in 28 of them. The size of the stones ranged from 3 mm×2 mm to stag-horn calculus. Conclusions The urinary calculi caused by melamine is sandy stone. Ultrasound result is equivocal in the disease, CT plain scan can be a method of choice. High frequency convex probe provides more clear images, more evident adminstrative levels of anatomise than general abdominal probe does. It is beneficial for diagnosing and differential diagnosing of these diseases.
