Painless urethral bleeding: an unusual presentation of Von Willebrand disease

Von Willebrand disease (vWD) is the most common bleeding disorder, and usually presents with either easy bruising or mucus membrane bleeding. Many patients are also diagnosed as a result of abnormal pre-operative laboratory tests. In this report, we describe two patients presenting with painless, persistent urethral bleeding as their initial manifestation of vWD. The first patient began bleeding after a Foley catheter was placed during a hospital admission for status epilepticus. A urologic examination demonstrated a wound in the posterior urethra. Despite repeated attempts at controlling the bleeding with cautery, the bleeding persisted. The second patient presented with spontaneous urethral bleeding and a normal urologic examination. Due to persistent bleeding, both patients underwent a coagulation evaluation that demonstrated the presence of type 1 vWD. The first patient had resolution of his bleeding following 5 weeks of Alphanate, a von Willebrand factor containing factor VIII concentrate, and aminocaproic acid. The second patient initially responded to desmopressin, but subsequently required Humate-P to achieve complete resolution. These cases illustrate the importance of an evaluation for bleeding disorders in patients with persistent bleeding from any site.
