Intravesical epsilon aminocaproic acid in management of intractable bladder hemorrhage.

Thirty-seven patients with intractable bladder hemorrhage were treated with intravesical epsilon aminocaproic acid (EACA). Radiation cystitis and cyclophosphamide-induced cystitis were the two most common causes of intractable bladder hemorrhage. Thirty-four patients responded to treatment. No side effects were noted. Intravesical EACA appears to be a safe and effective method to control intractable bladder hemorrhage.
