The patient was a 61-year-old male who had undergone right nephrectomy for nephrolithiasis 35 years before. He had been on hemodialysis for 6 years for chronic renal failure caused by left renal staghorn calculus and hydronephrosis. He was admitted to our hospital because of macroscopic hematuria and sense of residual urine which had persisted for 3 months. Cystoscopic examination showed an extensive papillary tumor in the urinary bladder, which histologically was an adenocarcinoma.
Giant left hydronephrosis associated with staghorn calculus noted by KUB and CT scan. Total cystectomy, intraoperative radiotherapy, and left nephrostomy were performed under the diagnosis of adenocarcinoma of the urinary bladder and left hydronephrosis.
The bladder tumor was found to be a mucinous adenocarcinoma. The patient died from a cerebral hemorrhage on the 17th postoperative day. At autopsy, tumors were found in the pelvis of the left kidney and the middle and lower regions of the ureter, which were adenocarcinoma like the bladder tumor.
Adenocarcinoma occurring simultaneously in the renal pelvis and bladder has not been previously reported to our knowledge, in Japan or elsewhere.
