title: [Fibroepithelial polyps of renal pelvis and ureter].
abstract: OBJECTIVE
  To analyze the results of surgical treatment of patients with long ureteral fibroepithelial polyps (FEP).
  
  
  METHODS
  From 2005 to 2014 three patients (1 man and 2 women) with large FEP were observed in our hospital. In 2 patients the base of the polyp was located in the proximal ureter and in 1 patient in the middle calyx of the single kidney. The fibroepithelial polyps were long and extended down to the lower third of the ureter (2) or protruded into the bladder (1). Endoscopic resection of the polyp was made in 1patient, resection of parenchyma in the middle calyx along with the base of FEP in 1 patient with the single kidney, and another patient underwent laparoscopic nephrectomy due to the absence of kidney function.
  
  
  RESULTS
  Endoscopic resection was successful; the operation lasted 45 minutes without complications. In the patients with a single right kidney operative time was 3.5 hours; during the operation, she received a blood transfusion. In the postoperative period, she underwent two hemodialysis sessions due to acute renal failure. Subsequently, her kidney function was restored. No FEP recurrences occurred in cases of organ sparing operations during follow-up. The postoperative period of the third patient submitted to laparoscopic nephrectomy was uneventful, creatinine levels remained in the normal range.
  
  
  CONCLUSIONS
  For long, large ureteral FEPs with a broad base the choice of surgical option depends on possibility of tumor visualization and functional state of the kidney.
