[Sonography in the evaluation of reduced function of kidney transplants (author's transl)]

Sonography of 58 kidney transplants has been performed in 56 patients and morphological alterations have been registrated. These results have been compared with clinical examination, blood samples and histological evaluation whenever possible. It is our opinion that certain sonographical phenomena exist, which make the rejection of kidney transplants most probable and even allow for differentiation of different degrees. We found a correlation of right results between sonography and final pathological diagnosis in more than 80% of our patients. Moreover sonography permits the diagnosis of ureteral obstruction or leakage.
