**5.1.5 Hematuria**

Gross hematuria with clots with no other identifiable cause is common among BPH patients. Faubert *et* al, showed more than 30% of patients with microscopic or gross hematuria (Faubert 1998). Evidence suggests that in the patients predisposed to hematuria the microvessel density in prostate is higher than in controls (Wein 2007), suggesting that vascular lesions can be the cause of hematuria.
