NCT04314323

Brief Summary

The aim of this study is to establish a nation-wide cohort study of idiopathic retroperitoneal fibrosis (IRPF) in China. Methods: All the patients fulfilling diagnostic criteria of IRPF would be enrolled from multi-centers around China. A online database system has been established. Endpoints: The primary endpoint is to investigate the clinical manifestations of Chinese IRPF patients; the secondary endpoints including the demographic features,laboratory characteristics, immunological tests, imaging and pathological features, in addition, the treatment and prognosis of the disease.
