A case of large bladder hemangioma successfully treated with endoscopic yttrium aluminium garnet laser irradiation

Bladder hemangioma is a rare benign tumor. While partial cystectomy remains an effective treatment option for large bladder hemangioma, the combined method of neodymium : yttrium aluminium garnet and holmium : yttrium aluminium garnet laser irradiation is an effective and less invasive treatment option. We report a case of large bladder hemangioma in an otherwise healthy 4‐year‐old boy, successfully treated with serial endoscopic yttrium aluminium garnet laser irradiation. There was no recurrence, and normal bladder function was preserved. Serial yttrium aluminium garnet laser irradiation is thus a useful, less invasive method for cases of large tumors.
