X-rays or scans are usually done to look for stones or other abnormalities. Some people may require a kidney biopsy or renal angiogram if there are pointers to suggest possible inflammation in the kidneys or problems with the blood vessels to the kidney . 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.
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. The loin pain haematuria syndrome has been known about for almost 30 years and there are no cases reported of the disease causing any damage to the function of the kidneys. Pain is the biggest problem in this condition. In some people it can be nothing other than an ache that disappears with time, but in others it can be a severe pain that comes and goes for years. Some people can be incapacitated by the pain, requiring time off work and strong painkillers.
