Transitional cell carcinoma of the renal pelvis has been encountered in 54 cases at the Jikei University Hospital and related facilities.
The purpose of this review was to determine the association of ureter and bladder lesion with the renal pelvic tumor.
There were 14 women and 40 men (a ratio of 1.0 to 2.9). The range of age was from 22 to 78 years with an average of 59.
Twenty-six of the 54 patients (48%) with urotherial tumors of the renal pelvis had a synchronous or asynchronous tumor in the ureter and/or bladder. Seven of 20 patients were found to have bladder tumors concurrent with their renal pelvic neoplasms. Subsequent bladder tumor occurred in 13 of 20 patients. It developed 3 to 26 months (average 9.8 months) after the treatment of the pelvic tumor. Two cases had a previous history of bladder tumor.
High recurrence rate of the bladder tumor was observed with the association of multifocal tumors of upper urinary tract lesions at the time of operation. From the point of surgical treatment the recurrent bladder tumor was much more satisfactorily prevented by complete nephro-ureterectomy including a cuff of bladder.
Histopathologically the grading of the bladder tumors was usually simillar to that of original pelvic lesion.
And the majority of bladder lesions were superficial.
