Transurethral coagulation for radiation-induced hemorrhagic cystitis using Greenlight™ potassium-titanyl-phosphate laser.

Abstract

OBJECTIVE:

The aim of this study was to to demonstrate the initial treatment outcomes of Greenlight™ potassium-titanyl-phosphate (KTP) laser on radiation-induced hemorrhagic cystitis.

BACKGROUND DATA:

Hemorrhagic cystitis is a common complication of radiation therapy for pelvic tumors.

MATERIALS AND METHODS:

From September 2004 to February 2011, 10 patients with radiation-induced intractable hemorrhagic cystitis underwent transurethral Greenlight KTP laser coagulation of the bladder. The power setting was limited to 20-30 W.

RESULTS:

Bleeding stopped in all cases after one session of laser treatment. Mean follow-up time was 17 months (6-36 months). All patients underwent cystoscopy 3 months postoperatively, and no bleeding or significant scar was found. Recurrence of significant bleeding was seen in one case 7 months post-operation, and was again cured by KTP laser. There were no complications from the procedures.

CONCLUSIONS:

Our experience suggests that transurethral coagulation using KTP laser is a safe and effective strategy for the treatment of hemorrhagic radiation cystitis.
