Echography of renal transplant patients.

Grey-scale echography has been found useful in the detection of rejection, dilatation of the renal cavity system and fluid collections around the renal transplant in 55 patients. Serial ultrasound examinations are essential for the diagnosis of acute rejection as demonstrated in 13 of 19 cases. Authors recommend the extension of ultrasonic examination to the upper abdominal organs and pelvis of renal transplant patients even in symptom-free cases, since in this way it is possible for early detection of occult abdominal diseases, which may jeopardize the success of surgery.
