What causes loin pain haematuria?
This is a difficult question to answer. Some doctors have suggested that spasm of blood vessels within the kidney causes the loin pain haematuria syndrome, but in most people who have tests looking for this, nothing is found. We know that the blood leaks into the urine within the kidney, but we do not know why the condition is so painful. One of the difficulties in treating this condition is that it is very variable between people who suffer it; it is not even certain if this is one condition or a group of similar diseases. Most cases occur in young women. There is a suggestion that previously having had kidney stones makes a person more likely to suffer the condition.
