[Ultrasonographic and x-ray diagnosis of nephrolithiasis]

Neither the ultrasonic, not the x-ray method alone cannot provide the correct diagnosis in nephrolithiasis. Ultrasonic scanning of the kidneys is indicated at the first stage of the diagnosis. In case of a concrement detection without dilatation of the pelvic calyceal system and the presence of a typical pattern of a calcified papilla or coral-like concrement on the picture the diagnosis can be considered made. If ultrasonic scanning detects, besides the concrement shade, a dilatation of the pelvic calyceal system, excretory urography and x-ray television pyeloscopy are necessary to specify the urodynamic state, that is important to predict the concrement of its fragments elimination under the effect of conservative therapy or long-distance lithotripsy.
