A CASE OF BILATERAL UROTHELIAL CARCINOMA OF THE UPPER URINARY TRACT

Abstract

A 76-year-old woman was admitted with complaints of general fatigue and consciousness disturbance. Clinical examinations showed that she was in a uremic state. Ureteral catheterization revealed an obstruction of the right ureter end. Right nephrostomy was performed, improving her general conditions. Further investigations indicated left renal pelvic carcinoma and right ureter carcinoma extending into the bladder. Left nephroureterectomy and right ureterectomy with total cystectomy were carried out. By pathological examination, the right ureter tumor was an invasive urothelial carcinoma extending into the bladder, and the left renal pelvic tumor was an invasive urothelial carcinoma invading almost of all the renal parenchyma, which has made the renal function extinct. She died of multiple liver metastases 9 months postopetatively. Reported cases of bilateral tumor of the upper urinary tract were reviewed and the causes of non-functioning kidney by renal pelvic tumor were discussed.
