Renal Biopsies in Post-liver Transplantation Patients With Renal Impairment: a Single-center, Prospective Cohort Study
Investigators will conduct this single-center, prospective cohort study to explore the prevalence and risk factors of renal function progression in post-liver transplantation patients with renal impairment after renal biospy and to understand the the pathology of kidney disease in post-liver transplantation patients with renal impairment.
