Abstract

Background: Ureteral fibro-epithelial polyp (UFP) is a rare benign ureteral tumor, and surgical removal of the polyps is still the preferred solution. Although many cases have reported polyps extending to the bladder, our case was the first to report a huge UFP that underwent endoscopic laser resection to highlight the urethra and cause severe end hematuria permanently.

Case presentation: In 2019, a 37-year-old woman came to the hospital because of hematuria and a dark red extraurethral mass. CTU inspection showed: filling defect between the right ureter and the bladder at the entrance of the bladder. After ureteroscopy, it was found that the ureteral mass came out of the urethral orifice. Then, under the direct view of the ureteroscope, a Ho:YAG laser was used to remove the tumor by cutting off along the its base, and the patient was discharged 3 days after the operation.

Conclusion: Urethral polyps from the ureter should be considered in the differential diagnosis of urethral neoplasms. Ho:YAG laser resection under ureteroscopy is an effective option for treating UFP, but be careful of ureteral stricture after surgery.

The total length of the tumor is approximately 12 cm, the surface is smooth, the diameter of the tube is approximately 0.8–1.8 cm, the cut surface is grayish red, and the edema is translucent. b H & E staining (× 100) showed that urothelial hyperplasia conformed to polypoid changes, but no dysplasia or malignancy. c Immunohistochemistry indicates positive Gata3 nucleus. d Immunohistochemistry indicates negative CK20 cytoplasm
