Abstract
1. A few experiential reports have recently made on each cases of pelvic, primary ureteral and secondary ureterovesical tumors, briefly with some literatures avaible on this subject considerated.
2. Pelvic tumor; Inpatient, who entered hospital complaining of hematuria and lower abdominal pain, result of X-ray finding tried several times was of great value in determining nephroureterectomy with partial cystectomy because X-ray showed nothing on kidney but the filling defect in lower part of the left ureter. It was histologically concluded that milliary nodes were observed in the renal pelvis and microscopic aspect meant capillary carcinoma and the stricture of ureter due to inflammation.
3. Primary ureteral tumor; Inpatient, who complained of symptomless hematuria, left ureteral nephroureterectomy with partial cystectomy was performed under the diagnosis of left tumor in recognition of the peculiar filling defect at the left ureteropelvic junction from an intravenous and retrograde pyelographies. It was determined the primary papillary carcinma of left ureter under the histological examination.
4. Secondary ureterovesical tumor; Inpatient, who had ever undergone right nephrectomy 8 months before under the diagnosis of right renal papillary tumor, thereafter had gradually increase of hematuria, similarly the rest ureterectomy with partial cystectomy was made under the diagnosis of the secondary papillary tumor. It was ureteral papillary carcinoma under the histological examination.
5. From these remarkable characteristics of tumor via upper urinary tract it should be, if possible, taken away with total nephroureterectomy and partial cystectomy.
