[Daily ultrasonic examinations of kidney transplants in the diagnosis of rejection].

The volume of transplanted kidneys was measured in 54 patients in the first 20 days post operation using short-term sonography. In non-rejecting patients it increased by 20% on average, by 35% in rejecting ones and by nearly 50% in rupturing patients. There were significant differences between the groups of rejecting and non-rejecting patients. Sonography is thus a suitable screening method for rejection diagnosis.
