Gross hematuria in a 3-year-old girl caused by a large isolated bladder hemangioma.

Hemangiomas of the urinary tract can arise anywhere along the system. Although rare, these lesions can result in significant hematuria, with potential for patient morbidity. We report a case of an isolated bladder hemangioma identified in a 3-year-old girl presenting with recurrent high-volume gross hematuria. The lesion was not amenable to endoscopic resection because of its size. We present our operative management strategy as a potential method for other urologists who may be presented with similar scenarios.
