Retroperitoneal fibrosis is a rare autoimmune related disorder that blocks the tubes (ureters) that carry urine from the kidneys to the bladder. Retroperitoneal fibrosis occurs when extra fibrous tissue forms in the area behind the stomach and intestines. The tissue forms a mass (or masses) that can block the tubes that carry urine from the kidney to the bladder. The cause of this problem is not known. It is most common in people aged 40 – 60. Men are twice as likely to develop the condition as women. Early symptoms include: dull pain in the abdomen that increases with time, pain and change of color in the legs (due to decreased blood flow), and swelling of one leg. Later symptoms include: decreased urine output, no urine output (anuria), nausea, vomiting, changes in thinking caused by kidney failure and build-up of toxic chemicals in the blood, and severe abdominal pain with hemorrhaging (due to death of intestinal tissue). The outlook will depend on the extent of the problem and the amount of damage to the kidneys. The kidney damage may be temporary or permanent.[rx]
Retroperitoneal fibrosis is a slowly progressive disorder in which the tubes that carry urine from the kidneys to the bladder (ureters) and other abdominal organs or vessels become blocked by a fibrous mass and inflammation in the back of the abdomen. The disorder may cause pain in the abdomen that worsens with time, pain or swelling of the legs, decreased urine output, and swelling of the scrotum in men.[1][2] Risk factors for retroperitoneal fibrosis include asbestos exposure, smoking, tumor, infection, trauma, radiotherapy, surgery, and use of certain drugs.[1][2][3][4]Treatment may include corticosteroids, tamoxifen, stents or surgery.[1]
Retroperitoneal fibrosis is characterized by inflammation and excessive scar tissue that develops in the back of the abdominal cavity. It can occur at any age, but appears most often between the ages of 40 and 60.[1][2] Men are twice as likely to develop the condition as women.[1]
Retroperitoneal fibrosis (RPF) is a rare condition where abnormal tissue growth occurs in the retroperitoneal space. Now, let’s unpack that: the retroperitoneal space is the area behind your abdominal cavity, and fibrosis means the development of excess fibrous or connective tissue. So, in simpler terms, RPF is when extra tissue forms in the back of your belly.
Types of Retroperitoneal Fibrosis
There are two main types of RPF:
- Idiopathic RPF: This type has no known cause, making it mysterious. It just happens without a clear reason.
- Secondary RPF: This type is linked to other medical conditions or factors. We’ll explore some of these causes in the next section.
What Causes Retroperitoneal Fibrosis?
Understanding the causes of RPF can be helpful. Here are 20 possible factors:
- Infections: Certain infections can trigger RPF.
- Medications: Some drugs may be linked to RPF development.
- Autoimmune Diseases: Conditions where the immune system attacks healthy tissues.
- Surgery: Previous abdominal surgeries can be a risk factor.
- Cancer: Some cancers, like lymphoma, may lead to RPF.
- Radiation Therapy: Past radiation treatments could play a role.
- Allergies: Severe allergies might contribute.
- Aortic Aneurysm Repair: This surgery may lead to RPF.
- Blood Clots: Conditions that cause blood clots may increase the risk.
- Vasculitis: Inflammation of blood vessels can be associated.
- Certain Inflammatory Diseases: Such as sarcoidosis or Wegener’s granulomatosis.
- Abdominal Trauma: Injuries in the belly region might be a factor.
- Familial RPF: In some cases, it can run in families.
- Obesity: Being overweight can increase the risk.
- Smoking: Tobacco use is a possible risk factor.
- Environmental Toxins: Exposure to certain chemicals might contribute.
- Chronic Kidney Disease: A connection between RPF and kidney problems exists.
- Age: It’s more common in people over 40.
- Gender: Men are more often affected than women.
- Genetics: Certain genetic factors may make someone more susceptible.
Common Symptoms of Retroperitoneal Fibrosis
Now that we know what causes RPF, let’s discuss the signs and symptoms that might indicate you have this condition. Here are 20 common symptoms:
- Flank Pain: Discomfort in the sides of your back.
- Abdominal Pain: Pain in your belly area.
- Weight Loss: Unexplained weight loss.

How is Retroperitoneal Fibrosis Diagnosed?
Getting a proper diagnosis is crucial for effective treatment. Here are 20 diagnostic tests and procedures that may be used:
- Blood Tests: Checking for inflammation or infection.
- Imaging Tests: Using X-rays, CT scans, or MRIs to visualize the retroperitoneal area.
