A Clinical Observation on Malignant Tumors of Renal Pelvis and Ureter / 대한비뇨기과학회지

ABSTRACT

A clinical observation was performed on 15 cases of the primary renal pelvic and the ureteral tumors, observed in our clinic during the period from Jan. 1962 to Dec. 198O. The results were as follows; The incidence of the renal pelvic and the ureteral tumors among the 335 genitourinary tumors during the period was 4.5% (15 cases). Male to female ratio was 2.8:1 and right to left ratio was 2:1 in the renal pelvic and the ureteral tumors. The seventy five percent of the ureteral tumor occurred in the lower ureter. 2. The most common symptom was hematuria in the renal pelvic and the ureteral tumors. 3. Urographic findings in the renal pelvic tumor were filling defect in 5 cases (71.4%) and non functioning kidney in 2 cases (28.6%). In the ureteral tumor, hydronephrosis was 5 cases (62.5%), non functioning kidney in 3 cases (37.5%) and filling defect in 2 cases (25.0%). 4. Treatment of the renal pelvic and the ureteral tumors was performed surgery in all cases. In the renal pelvic tumor, 5 nephroureterectomies, 1 nephrectomy and 1 nephroureterctomy with excision of the bladder cuff were performed. In the ureteral tumor, 5 nephroureterectomies with excision of bladder cuff and 3 nephroureterectomies were done. 5. Histologic analysis showed transitional cell carcinoma in all cases. Histologic grade and stage showed a close correlation with prognosis.
