A 59 year-old man, previously healthy first visited our urological clinic on February 25, 1974, with 2-month old intermittent asymptomatic gross hematuria. Urethrocystoscopy revealed a slight stenosis on the membranous urethra and a hen's egg size solid tumor was found on the left lateral wall of the urinary bladder by cystoscopic optics. The mucosa of other parts of the urinary bladder was without remarkable change and the right ureteral orifice was normal. However, a left ureteral orifice was not found because of the infiltration of the tumor. On March 17, 1974, the patient was admitted to our hospital for treatment. Excretory urogram revealed a delay of excretion and a dilatation of the upper urinary tract on the left side in contrast to the right side. A large round defect of the contrast medium at the left lateral side of the urinary bladder was seen by excretory cystography. Pelvic angiography using air cystography for negative contrast revealed abnormal tumor vessels and tumor stain. There was no sign for the metastatic changes in the lungs, gastrointestinal tract and lymphnode by other radiological examinations. Urinary exfoliative cytologic examinations were performed several times using the Papanicolaou stain and the cytologic diagnosis was always transitional cell carcinoma class IV or V. Laboratory tests, including hemograms, serum electrolytes, blood urea nitrogen, creatinine, glucose, calcium, phosphate, serum proteins were normal. An isotope liver scan was normal. The patient underwent a total cystectomy with an ileal conduit as an urinary diversion.
