Laser treatment of bladder hemangioma.

Bladder hemangiomas may occur singly or in association with systemic arteriovenous malformations. A total of 13 patients with bladder hemangiomas underwent treatment at this university. All patients had recurrent bleeding and neodymium:YAG laser energy was delivered endoscopically to the hemangioma. No treatment-related bleeding occurred in any patient, and all had a significant decrease in the frequency and intensity of bleeding episodes. Followup cystoscopic examinations have shown either complete eradication of the hemangioma or a marked decrease in size. Neodymium:YAG laser irradiation provides results superior to alternative therapy and is the preferred treatment for most patients with bladder hemangioma.
