title: Obstructive uropathy caused by bilateral synchronous ureteral carcinoma: report of a case.
abstract: We report on a 67-year-old man with bilateral, synchronous, ureteral transitional cell carcinoma. He presented with bilateral flank pain accompanied by nausea, vomiting and oliguria. Bilateral hydronephrosis with upper ureteral filling defects was found on antegrade pyelogram. After urinary diversion with bilateral percutaneous antegrade drainages for 6 days, serum creatinine fell from 10.1 to 4.7 mg/dl. Exploration revealed bilateral upper ureteral tumors. Right nephroureterectomy and left ureterectomy with left nephrostomy were done.
