Treatment of Ureteral Fibroepithelial Polyp by Ureteroscopy Combined with Holmium Laser or Thulium Laser: A Retrospective Study.
OBJECTIVE
Ureteral fibroepithelial polyps (UFPs) are rare benign tumors and ureteroscopy has been used for treatment. We compared the effect of UFP by ureteroscopy combined with holmium laser or thulium laser.


METHODS
Twenty-five patients with UFPs were treated in our hospital between May 2003 and April 2013. All patients received ultrasound check and intravenous urography (IVU). We performed ureteroscopy operation and found ureteral polyps, so we resected the polyps with holmium laser (12 cases) or thulium laser (13 cases). During the 3-year follow-up, all patients received IVU 2 or 3 months after the double-J stent was removed, and ultrasonic checks every 3-6 months after that.


RESULTS
All patients had UFPs resected. Three patients in the holmium laser group had ureteral perforation during operation, and four patients in the holmium laser group developed ureterostenosis. No patients in thulium laser group experienced any severe complications during the procedure. Further, during follow-up, there was no indication of an increase of hydronephrosis in any patients. These findings lead to conclude there were no developments of ureterostenosis nor an experience of any reoccurrence in thulium laser group.


CONCLUSIONS
Ureteroscopy operations, combined with holmium or thulium laser resection, are effective methods for treating UFP, but thulium laser does better in reducing the incidence of ureterostenosis.
