The cause of<unk>  is not known. One theory proposes that it is caused by a thin glomerular basement membrane and red blood cell (RBC) renal tubular congestion that leads to swelling of the kidney and distension of the renal fascia resulting in<unk> . Researchers have hypothesized that the<unk>  may be due to blood vessel diseases of the kidney, spasms of the kidney vessels, or other bleeding disorders (coagulopathy). The<unk>  in<unk>  may be due to an abnormal (thick or thin) glomerular basement membrane. The glomerular basement membrane is a tissue in the kidney that filters the blood. An abnormal glomerular basement membrane may allow red blood cells into the urinary space. Because kidney stones are so common in people with<unk> , crystals in the kidney tubules may also play a part in bleeding and<unk> . Other speculations on cause include * IgA nephropathy. This is a condition in which small amount of a type of normal antibody (called IgA) get stuck in the kidney as it passes through in the bloodstream. This is a chronic condition, which sometimes goes away on its own but occasionally can cause damage to the kidneys. A related condition called IgM nephropathy can sometimes cause<unk> . * Thin membrane disease. In this condition the membrane that filters the blood to make urine is too thin, and blood can pass across it in very small amounts. In a few cases of this condition, there is<unk>  in the kidneys, usually occurring in attacks every so often. Although this condition can be<unk> ful, kidney failure does not seem to occur in the long term, so that the only real problem is the symptoms. * Infection. In some cases,<unk> <unk> -haematuria<unk>  occurs after a bladder infection with involvement of the kidney. Even when the infection has been treated and bugs can no longer be found in the urine,<unk>  may persist for 6 months, or even longer in some cases. * "Classic<unk> <unk> -haematuria<unk> ". Some patients have none of the above diagnoses. In these cases there may be minor abnormalities on a kidney biopsy. Angiogram tests to look at the blood vessels in the kidney may show abnormal blood flow, perhaps causing a cramp like<unk> . The cause is not fully understood. It certainly is more common in women than in men, and there may be hormonal influences. Some women find the<unk>  is worse at different times of their menstrual cycle, or comes on during pregnancy, or if they are taking oral contraceptives. It has also been reported to be caused by microscopic granules of calcium oxylate into the glomerulus itself, causing blood vessels to rupture and increase the distention of the renal capsule. This condition may persist for some years, and can be lifelong. Damage to the kidneys leading to kidney failure does not occur. However, because<unk>  is unusual in patients older than 60 years, some clinicians believe that<unk>  eventually resolves. At this time no cure has been found for this disease.<unk>  is a debilitating disease due to chronic<unk>  and the inability to know how to control the glomerular aspect. The<unk>  of<unk>  can be worsened by acts as simple as riding in the car and undertaking daily activities. Many people with this disease are unable to maintain employment due to the debilitating<unk> . Unpublished research by Dr. Ahmed Ghanem (who has cared for well over 100 women with<unk>  found that untreated Symptomatic Nephroptosis - SN (Hypermobile kidney) can lead to<unk> . Nephropexy can help to relieve symptoms. Severe renal colic caused by kinking ureter.<unk>  classically relieved a little by going on all fours with hips higher than head.
