[The value of sonography in evaluation of unilateral nonvisualized kidney (author's transl)].
In a comparative study with 35 patients, sonography, angiography and radiorenograms are investigated on their validity for evaluation of nonvisualized kidneys. In our group of patients, angiography showed an accuracy quota of 97% (34/35) and sonography showed an accuracy quota of 88% (31/35). In 12 patients, the radiorenograms unequivocally show functional loss with the nephrectomy type. Sonography should be used first as a simple noninvasive procedure. It is independent of the remaining renal function and indicates the size of the organ. For hydronephrosis sonography cannot clarify the cause of the urinary stasis in some cases; for this purpose, further examinations are indicated (retrograde pyelography, antegrade pyelography).
