Enhanced CT and MRI are currently the most valuable auxiliary examination methods for diagnosing and determining the degree of retroperitoneal fibrosis. CT can exclude retroperitoneal tumors, and when there are symmetrical and continuous plaque-like soft tissue masses on both sides of the spine, it is of great significance for diagnosis. Erythrocyte sedimentation rate and alkaline phosphatase are also significant for disease diagnosis.
1, Blood Test There may be red blood cells, decreased hemoglobin; increased eosinophils, and hematocrit less than33percent.
2, Urinalysis 1/3patients have proteinuria.
3, Erythrocyte Sedimentation Rate 94percent of patients initially have an increased erythrocyte sedimentation rate.
4, Renal Function Clinically75percent of patients have varying degrees of renal function damage, manifested as oliguria, azotemia, such as increased blood creatinine, urea nitrogen.
5, Alkaline Phosphatase In recent years, alkaline phosphatase has been considered as a marker of the disease, and the increase of alkaline phosphatase is of great significance for the diagnosis of the disease.
6, Ultrasound Examination This examination is non-invasive, non-radioactive, inexpensive and convenient, and can be one of the screening and diagnostic methods for the disease.
7, X-ray Examination.
8, Magnetic Resonance Imaging (MRI).
9, Radionuclide Scanning.
10, Positron Emission Tomography (PET).
