[Computer tomography of the renal bed after nephrectomy].

An early diagnosis of the tumour relapse after performed nephrectomy for a malignant kidney tumour is necessary in order to influence further fate of the patient. The most suitable method for determining a correct diagnosis is computer tomography. The authors present a cohort of 79 patients with a pathological finding in 21 of them. In the other patients the finding after the operation proved to be normal, i.e. the bed was free after the performed nephrectomy, retroperitoneal vessels were free and the line of m. psoas on the surgically treated side proved to be intact. Computer tomography can prove not only the relapse, but also metastatic affection of other organs, particularly in the liver and adrenals.
