title: [Fibroepithelial polyp of the renal pelvis. A case report].
abstract: Benign tumors of the renal pelvis are relatively rare, and only a few reports have been published so far. Recently we experienced a case of a 50-year-old woman with a fibroepithelial polyp in the left pelvis. Drip infusion pyelography and abdominal CT revealed a filling defect and tiny renal stones in the left pelvis under the study of her urinary blood occult. A transitional cell carcinoma of the renal pelvis was suspected, so a left total nephroureterectomy was done. The pathological diagnosis of this tumor was fibroepithelial polyp. As it is said that preoperative diagnosis of such a polyp is difficult, preoperative ureteroscopy or perioperative pathological diagnosis by frozen sections should be attempted. But it is difficult to avoid a nephroureterectomy because low incidence of the disease.
