A CASE OF PN₁ URETERAL TUMOR WITH SPECIAL REFERENCE TO THE SIGNIFICANCE OF LYMPHADENECTOMY

Abstract

A 59-year-old woman visited our hospital because of gross hematuria and left flank dull pain in May 1985. On IVP left renal function was severely deteriorated. Retrograde ureteropyelography revealed an irregular filling defect in the left lower ureter. She underwent left nephroureterectomy and left pelvic lymphadenectomy. Histological examination disclosed transitional cell carcinoma in the left lower ureter invading the ureteral smooth muscle and not penetrating it. Of 16 excised left pelvic lymph nodes only one external iliac node had metastatic lesion. After the operation adjuvant chemotherapy with cisplatin and methotrexate was carried out. She was well without recurrence in 18 months after the surgery. We discussed the significance of lymphadenectomy for the renal pelvic and ureteral tumor.
