Abstract:
An 85-year-old female was referred to our hospital with chief complaints of right flank pain and gross hematuria. Ultrasonography demonstrated right hydroureteronephrosis and a thumb head-sized solid mass in the lower third of the right ureter. Cystoscopy revealed papillary tumors near the right ureteral orifice. Under the preoperative diagnosis of right ureteral tumor and bladder tumor, transurethral resection of bladder tumor, right nephroureterectomy and partial cystectomy were performed. The gross specimen of the ureter contained a 5 x 3 x 1 cm, polypoid and smooth-surfaced tumor. The pathological diagnosis of the ureteral tumor was transitional cell carcinoma with inverted proliferation, grade 1 >> grade 2. On the other hand, the bladder tumor was papillary transitional cell carcinoma, grade 1. This is a case in which tumor development showed two different types.
