[Kidney-sparing surgery for recurrent ureteral and bladder cancers in an aged patient with functionally solitary...

A 79-year-old woman was admitted with recurrent ureteral and bladder cancers. She had a horseshoe kidney with a non-functioning right renal unit. Fifteen months earlier, multiple urothelial tumors had first developed in the left upper ureter and bladder. Transurethral resection of bladder tumor (TUR-Bt) and partial ureterectomy (2 cm) had been performed. Presently, the recurrent tumors were located at the left lower ureter and bladder. Considering the high age of the patient, TUR-Bt and partial ureterectomy (5 cm) were performed. Besides urothelial cancers, she had been operated for carcinomas of the colon, uterus and stomach. Kidney-sparing therapy has successfully maintained her quality of life.
