[Renal cell carcinoma and bladder tumor observed in the Automated Multiphasic Health Testing and Services of Tokai University Hospital].

From June 1975 through December 1983, 48,604 individuals consisting of 34,535 males and 14,069 females underwent health examinations at the Automated Multiphasic Health Testing and Services (AMHTS) Center in Tokai University Hospital. There were five patients with renal cell carcinoma and three with bladder cancer. We reviewed the clinical courses of these patients and discussed the early detection of urological cancers in AMHTS. Patients with renal cell carcinoma were brought to the urology department with various findings in AMHTS. A 44-year-old male was referred to us for the investigation of multiple metastatic shadows in the chest X-P and left renal tumor was diagnosed by intravenous pyelography (IVP) and computed tomography (CT). Renal tumor of a 57-year-old male was diagnosed by the investigations of abnormal renal calcifications found in AMHTS. A 39-year-old female had undergone health check-ups several times but was not found to have a renal tumor. The diagnosis of left renal tumor was made by the abdominal CT carried out after the operation on cerebellar hemangioblastoma. The fourth patient was a 60-year-old female with microscopic hematuria found in AMHTS and the diagnosis was confirmed by calyceal deformity shown in IVP. The last patient was a 64-year-old male and was accidentally demonstrated to have a right renal mass by ultrasonography when he was reexamined for the hepatic abnormality found in AMHTS. He showed microscopic hematuria in the AMHTS urinalysis. The diagnosis was confirmed by IVP, CT and renal angiography.(ABSTRACT TRUNCATED AT 250 WORDS)
