Short Case Report

Contralateral Ureteric Metastasis from Renal Carcinoma A woman, 55, complained of haematuria and left loin pain for 6 months. No abnormality could be found on clinical examination. An IVP showed a non-functioning right kidney and a space-occupying lesion i n the lower pole of the left. Ascending ureterography demonstrated a filling defect, obstructing the right ureter at the level of L4-5 (Fig.) and a distorted pelvi-calyceal system in the lower pole of the left kidney. Selective renal arteriography confirmed the diagnosis of left reniil tumour.

The right ureter was explored first and a smooth, 2-cm-long polypoid lesion was resected and end-to-end anastomosis of the ureter performed. Histology showed asecondary clear cell tumour consistent with a renal primary. Her postoperative recovery was uncomplicated. After convalescence a repeat IVP showed very poor function of the right kidney. A right ureteric catheter collection of urine showed very poor renal function. The left kidney was explored and a 5 cni lower pole clear cell carcinoma was removed by a gth partial nephrectomy. Postoperatively her blood urea rose t o ;I peak of 15.6 mmol/l. but fell to 12.6 niniol I. by discharge. She remains well at 3 monthh. Cnmment Metastases from renal cell carcinoma ;ire rarely found in the ureter, especially the contralateral one. The presence of a ureteric secondary from a renal carcinoma is usuall! indicative of genernlised metastatic disea4c (Gross and Minkowitz, 1971).
