Ureteral fibroepithelial polyp mimicking urothelial carcinoma

A 69-year-old Chinese woman presented with one episode of painless visible haematuria. She had recurrent urinary tract infections. She is a nonsmoker and had no previous contact with anilines or other chemicals. Examination was unremarkable. Computed tomography (CT) urography was carried out and revealed a 1.0 × 0.9 cm soft-tissue density in the posterior urinary bladder wall adjacent to the left vesicoureteric junction (Figure 1). There was a filling defect in the left distal ureter with mild to moderate left hydronephrosis and mild perinephric stranding. Flexible cystoscopy showed a left distal ureteric lesion extruding from the left ureteric orifice into the bladder (Figure 2). A left retrograde pyelogram with ureteroscopy and laser excision of the left ureteric lesion was performed. A retrograde pyelogram performed intraoperatively revealed a filling defect beyond the left midureter above the upper border of the sacroiliac joint. Ureteroscopy demonstrated a long, stalk-like left ureteric lesion arising from the ureteric
