PURPOSE: We demonstrate the successful conservative management of a ureteral tumor in a horseshoe kidney.
MATERIALS AND METHODS: A patient with low grade transitional cell carcinoma of the left lower ureter had asymptomatic horseshoe kidney. Biopsy specimen revealed low grade tumor in the lower urinary tract that was associated with a congenital abnormality. The patient underwent total ureterectomy with bladder cuff excision and ileal ureteral interposition.
RESULTS: With this technique renal function was preserved without resection through the isthmus of the kidney. The patient has no evidence of recurrent disease after 20-month followup by cytology, computerized tomography, excretory urogram and cystoscopy.
CONCLUSIONS: Organ preserving surgery is an alternative to total nephroureterectomy in lower ureteral tumors in select patients.
