<unk>  <unk>  is the combination of debilitating unilateral or bilateral flank<unk>  and microscopic or macroscopic amounts of blood in the urine that is otherwise unexplained.<unk>  <unk>  is a poorly defined disorder characterized by recurrent or persistent<unk>  (flank)<unk>  and<unk>  that appears to represent glomerular bleeding. Most patients present with both manifestations, but some present with<unk> <unk>  or<unk>  alone.<unk>  episodes are rarely associated with low-grade fever and dysuria, but urinary tract infection is not present. The major causes of flank<unk>  and<unk> , such as nephrolithiasis and blood clot, are typically not present. Renal arteriography may suggest focally impaired cortical perfusion, while renal biopsy may show interstitial fibrosis and arterial sclerosis. The<unk>  is typically severe, and narcotic therapy is often prescribed as a way to manage chronic<unk> . Sleep can be difficult because the supine position increases pressure on the flank. The onset of<unk>  is often associated with nausea and vomiting, making<unk>  management by oral opiates complicated.
