Abstract
A 68-year-old man undergoing hemodialysis for a renal failure due to polycystic kidney (PCK) was pointed out having gastric cancer and underwent a gastrectomy. PCK is transmitted as an autosomal dominant trait and ends up uremia. In patients with PCK, the bilateral kidneys massively enlarge by numerous cysts. PCK is expected to have a good prognosis compared with other diseases causing renal failure, because heart failure is relatively rare in PCK due to mild degrees of anemia and preservation of urinary output. But at operation, enlarged kidneys can occupy the procedure field, and once the cystic wall is injured we need a nephrectomy for an uncontrolled bleeding. Rarely, perinephric or retroperitoneal hematona may occur after the operation due to a rupture of the renal cyst. Cerebral aneurysm, heart vulve disorder, and diverticula in the colon are often coexistent with PCK so that we should pay attentions to them in periopetative period. PCK patients account for about 3% of all patients on hemodialysis. In general, hemodialysis patients are more prone to gain some malignant disease, especially gastrointestinal carcinoma. Regular survey of the GI tract must be made for such patients.
