[The ultrasonic diagnosis of ureteral stones in children].

Ultrasonography (USG) was performed in 117 children aged 8 months-14 years with ureterolithiasis. X-ray and ultrasonic evidence was compared for the upper, middle and low parts of the ureter. USG proved preferable for imaging of the upper and low ureter, x-ray negative concrements, in loss of renal function, while x-ray was much more informative for visualizing middle part of the ureter. Thus, USG is thought highly effective in diagnosis of ureterolithiasis in children.
