The present paper describes a case of a male tailor, ages 50 years, who underwent complete removal of the whole urinary tract as a treatment for bilateral asynchronous renal pelvic and bladder tumors. Left total nephro-ureterectomy was carried out in May 1971. The pathological examination of the specimen revealed non-invasive transitional cell carcinoma grade I-II. After 4 years from the above operation, small papillary tumors were recognized in his urinary bladder for several times during the following few years and managed with transurethral resection and fulguration. All of the tumor specimens showed almost similar histological findings as the initial renal pelvic tumor. In June 1979 a quickly growing tumor was found in the residual right pelvis, while he was receiving vesical instillation of antitumor agents. Lymphangiogram, lung tomogram and scintigram of the liver and bones revealed no evidence of metastases. Although there were no obvious tumors in the bladder cystoscopically, a tiny tumor was found at the lower portion of the right ureter. Therefore, right total nephro-ureterectomy and cysto-urethrectomy were performed. Microscopically, both tumors of the right renal pelvis and the ureter were a grade I-II transitional cell carcinoma without invasion. No cancerous lesions were found in the bladder and urethra. His post-operative course has been uneventful without any signs of tumor recurrence under maintenance hemodialysis for 9 month.
Bilateral renal pelvic tumor is rare and 21 previously reported cases of bilateral renal pelvic tumor were compared and discussed.
