Hematuria as the only symptom at initial presentation of hypovolemic shock caused by ruptured renal arteriovenous malformations.

ABSTRACT

Gross hematuria is a very common complaint in emergency departments and outpatient clinics. Globally, the incidence of hematuria is 4 per 1000 patients per year. Infection, urolithiasis, and neoplasm are the most common etiologies. However, hematuria rarely causes hypovolemic shock or an emergent, life-threatening condition at the initial presentation. In this report, we describe the case of a 64-year-old man who suffered a life-threatening gross hematuria in a very short time due to ruptured renal arteriovenous malformations (AVMs).
