Five cases of chronic hemodialysis patients complicated with bilateral renal cell carcinoma

The incidence of renal cell carcinoma in chronic dialysis patients is higher than that in the general population. In our hospital and its affiliated hospital, routine examination including sonographic examination and CT scan have been performed since 1994. As a result, 5 cases were found to have bilateral renal cell carcinoma and were treated surgically. All cases were male, 47.2±3.3 years old, and treated by hemodialysis for 228.0±51.2 months. Renal failure in these 5 cases was due to chronic glomerulonephritis in 3 cases, and idiopathic in 2 cases. None of these patients demonstrated diabetes mellitus. In 3 cases, clinical diagnosis and surgery on the left and right kidneys were performed at different times. In the other 2 cases, the left and right nephrectomy were performed simultaneously. In these 10 kidneys in 5 cases, clinical diagnosis was based on sonographic examination in all 10 kidneys, CT scan in 9 kidneys, angiography in 2 kidneys. Soon after surgery, anemia worsened transiently in one case, but blood pressure did not changed significantly in any case.
