What are the causes of Retroperitoneal Fibrosis?

Retroperitoneal fibrosis occurs when extra fibrous tissue forms in the area behind the stomach and intestines. The tissue forms a mass (or masses) or tough fibrotic tissue. It can block the tubes that carry urine from the kidney to the bladder.

The cause of this problem is mostly unknown. It is most common in people aged 40 to 60. Men are twice as likely to develop the condition as women.

What are the symptoms of Retroperitoneal Fibrosis?

Early symptoms:

  • Dull pain in the abdomen that increases with time
  • Pain and change of color in the legs (due to decreased blood flow)
  • Swelling of one leg

Later symptoms:

  • Decreased urine output
  • No urine output (anuria)
  • Nausea, vomiting, changes in mental status caused by kidney failure and build-up of toxic chemicals in the blood
  • Severe abdominal pain with blood in the stool (due to death of intestinal tissue)

What are the current treatments for Retroperitoneal Fibrosis?

Corticosteroids are tried first. Some health care providers also prescribe a drug called tamoxifen.

If corticosteroid treatment does not work, a biopsy should be done to confirm the diagnosis. Other medicines to suppress the immune system can be prescribed.

When medicine does not work, surgery and stents (draining tubes) are needed.
