These can be symptoms of kidney damage. According to the National Organization for Rare Diseases , the exact cause of this condition is unknown in about two-thirds of cases. Age and gender are the greatest risk factors for the disease.

The condition occurs twice as often in men as in women. These can include: tuberculosis actinomycosis, which is a bacterial infection histoplasmosis, which is a fungal infection recent trauma of the abdomen or pelvis abdominal or pelvic tumors The disorder can also be associated with: recent surgery on the abdomen or pelvis the use of cancer treatments involving external beam radiation certain medications to treat migraines and high blood pressure Potential Complications The complications associated with this disease vary.

The size and location of the excess tissue growth can cause damage to various areas served by the abdominal aorta. If this condition goes untreated, the most serious problems result from swelling and blockage of the ureters. This may result in chronic kidney failure and long-term blockage of the ureters, which can cause urine backup and kidney swelling. Additional tests used to confirm the diagnosis include: blood tests to measure kidney function, anemia, and inflammation an X-ray of the kidneys and ureters, which is called an intravenous pyelogram an ultrasound of the kidneys a biopsy to check for cancer cells Treatment for Retroperitoneal Fibrosis Treatment varies depending on the severity and location of the fibrosis.

This is done by draining the urine with a stent, or drainage tube, inserted through your back and into your kidney. A stent may also be run from your bladder through the ureter into the kidney. In some cases, surgery may be required. It may be used to: free the affected ureter from the fibrosis wrap the affected ureter in fat tissue from the intestines to protect it from fibrosis regrowth reposition the affected ureter away from the inflammation to prevent the blockage from happening again The goals of treatment are to remove the blockage, repair the affected ureter, and prevent it from happening again.

For many people, treatment requires both medication and internal intervention. Long-Term Outlook for Retroperitoneal Fibrosis If the condition is diagnosed and treated at an early stage, the long-term outlook for patients can be very good.

However, in cases where the kidneys are severely affected, damage can be permanent, leading to the need for a kidney transplant. How to Prevent Retroperitoneal Fibrosis Since the majority of cases cannot be linked to any specific cause, prevention may not be possible.

However, the condition is associated with the use of some medications to treat high blood pressure and medications to treat migraines called ergotamines. Ask your doctor about the possible side effects of these types of drugs and whether alternatives are available.
