Abstract:

Chronic kidney diseases (CKD) are very common in clinical work，including glomerulonephritis，pyelonephritis，nephrotic syndrome，renal tubular interstitial disease，diabetes kidney disease， hypertension， and renal vascular disease and others. Patients with CKD are susceptible to infectious disease. And infection will always prompt chronic renal failure due to deteriorated kidney function. Infection is  usually  a direct cause of death for patients with CKD. Therefore， more knowledge about the risk factors and characteristics of CKD is helpful to treat the infection and improve the prognosis of patients with CKD.

Key words: kidney diseases, kidney failure, infection, antibacterial , agents, prognosis
