[The echotomographic study of renal transplants]

The authors emphasize the role of renal sonography in detecting post renal-transplant complications, such as fluid collections and hydronephrosis. Ultrasonic study proved also to be useful in the diagnosis and follow-up of renal allograft rejection. A total of 32 renal allograft patients were studied. Focal areas of decreased parenchymal echogenicity were the most striking sonographic finding in renal rejection. Cortico medullary demarcation was difficult to interpret and was inconsistently related to rejection.
