両側性腎癌の1例

Abstract

A 60-year-old man, who complained of gross hematuria, was admitted because of bilateral renal space occupying lesions on CT-scan. DIP revealed that the right pyelogram was compressed medially and the left pyelogram showed a filling defect due to the presence of coagula. Selective renal arteriography revealed that right kidney was enlarged and had a hypervascular tumor laterally, and left kidney had two oval hypervascular tumors at the upper and middle portions. Von Hippel-Lindau sydrome, tuberous sclerosis and metastatic renal cancer were ruled out as a result of the other examinations. No distant metastases were observed by bone scanning, liver scanning, lymphangiography and chest X-ray studies. Through lumbar incision, bilateral nephrectomy was performed and A-V shunt was constructed on the same time. Hemodialysis was started on the next day. Convalescence was uneventful. But the patient died 67 days after operation with cardiac failure during hemodialysis at the other hospital.
