[Transurethral resection of papillary tumor in the lower end of the ureter: report of two cases].
Two cases of papillary ureteral end tumors, treated by transurethral resection are presented. Case 1: A 71-year-old female visited us for asymptomatic macroscopic hematuria. Cystoscopy revealed a papillary pedunculated tumor in the bladder protruding from the right ureteral orifice. Under a diagnosis of superficial tumor at the right ureteral end, transurethral resection was performed using a rigid ureteral resectoscope. Pathological examination revealed transitional cell carcinoma, grade 2 without muscular invasion. There is no evidence of recurrence after 25 months of follow up postoperatively. Case 2: On a routine cystoscopy after transurethral resection of bladder tumor in a 68-year-old male, papillary pedunculated tumors protruding from the right ureteral orifice were found. Under a diagnosis of superficial tumor at the right lower ureter, transurethral resection was performed using cold cup forceps and loop electrocoagulation. The tumor was transitional cell carcinoma, grade 1 without invasion. No evidence of recurrence was detected 15 months postoperatively. Transurethral resection of the ureteral tumor at the lower end appeared to be useful for the selected cases. The indications, complications and follow up for this procedure were discussed.
