Background and Objective Urethral hemangiomas are rare. They vary in size from pinpoint masses to extensive honeycomb‐shape deformities leading to significant hematuria. For extensive lesions, therapeutic options have included extensive surgical resection and reconstruction or multistaged neodymium:yttrium‐aluminum‐garnet (Nd:YAG) laser photocoagulation. We report our experience with the use of potassium titanyl phosphate (KTP/532) laser for treatment of the extensive form. Study Design/Materials and Methods A 7‐year‐old boy presented with a 2‐week history of urethral bleeding. He had extensive hemangiomas of the genital and perineal regions. Cystourethroscopy disclosed diffusely scattered honeycomb‐shape hemangiomatous malformation of the anterior urethra. KTP/532 laser energy was delivered transurethrally to the hemangiomatous areas until they blanched. Results The Foley catheter was removed 24 hours postoperatively, and the patient voided clear urine without difficulty. He has remained trouble‐free for more than 2 years. Conclusion Judicious endoscopic single‐stage therapy with KTP/532 laser may obviate open surgical intervention in most cases of extensive and symptomatic urethral hemangiomas. In view of our observation and the literature, KTP/532 laser therapy should be considered the first line of treatment. © 1996 Wiley‐Liss, Inc.
