title: [Primary ureteral tumor in the residual ureter: a report of two cases].
abstract: Two cases of primary ureteral tumor in the residual ureter are reported. One was in a 40-year-old woman who had undergone simple nephrectomy for renal tuberculosis 6 years earlier. The other was in a 59-year-old man 11 years after ureterostomy for hydronephrosis. They presented with hematuria. Cystoscopic examination revealed a ureteral tumor out of the residual ureteral orifice. Computed tomographic scan showed a perivesical mass attached to the urinary bladder. It is useful for examination of ureteral stump's condition. We performed ureterectomy. The pathological study revealed the former high grade transitional cell carcinoma with squamous cell carcinoma and lymph nodes metastasis and the latter low grade transitional cell carcinoma. They have been free of disease for 5.5 years and 1.75 years, respectively. These cases are the nine and tenth reports of primary ureteral tumor of the ureteral stump in the Japanese literature.
