Objective: To investigate the main causes of chronic renal failure (CRF) and the differences in how subpopulation is affected by these causes, and to determine the morbidity of anemia and hypertension, and the relation between age and gender in CRF patients.
Methods: We chose 1137 inpatients diagnosed as CRF in the Department of Nephropathy of 2nd Xiangya Hospital of Center South University from January 1996 to March 2002. We collected the information on name, gender, age, admission number, diagnosis, blood pressure, blood routine, renal function, and creatinine clearance rate.
Results: Chronic glomerulonephitied accounted for 56.4% as the leading cause, followed by hypertensive nephropathy (14.3%), obstructive nephropathy (7.2%), and diabetic nephropath (6.7%). Gender influenced the incidence of some diseases. Most patients were companied with anemia (90.7%) and hypertension (72.6%).
Conclusion: The main causes of CRF include chronic glomerulonephitis, hypertensive nephropathy, obstructive nephropathy, and diabetic nephropath.
