  FIG. 1 (A) Longitudinal ultrasonography showed a mildly echogenic mass (arrowhead) and dilated upper ureter (arrow). (B) Intravenous pyelogram showed left hydronephrosis with a dilated renal pelvis with corkscrew narrowing and intraluminal nonopaque and smooth filling defects (arrow). (C) 99mTc diethylenetriamine pentaacetic acid renography showed the obstructive pattern of the left kidney on the renogram after furosemide administration. A serial excretion film demonstrated isotope retention in the left kidney of up to 59 minutes.

• 

  FIG. 2 Intraoperative images and histologic findings. (A) Fibroepithelial polyps (FEPs) were exposed via ureterotomy. Multiple slender, cylindrical ureteral polyps with smooth surfaces were observed. (B) Morphology of the multiple excised long FEPs. (C) Histologic examination showing FEPs composed of loose fibrovascular connective tissue covered with a layer of normal urothelium (H&E, ×40).
