Retroperitoneal fibrosis

  • Alternative Names

    Idiopathic retroperitoneal fibrosis; Ormond's disease


    Symptoms

    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 thinking caused by kidney failure and build-up of toxic chemicals in the blood
    • Severe abdominal pain with hemorrhaging (due to death of intestinal tissue)

    Signs and tests

    Abdominal CT scan is the best method to reveal a retroperitoneal mass.

    Other tests that can help diagnose this condition include:

    • BUN and creatinine blood tests
    • Intravenous pyelogram (IVP)
    • Kidney ultrasound
    • MRI of the abdomen

    A biopsy of the mass may also be done to rule out cancer.
