Other causes of renal impairment include HIV-AIDS, hepatitis, drug use and recurrent urinary tract infections, according to WebMD. Renal impairment is the result of damaged kidneys causing waste accumulation in the blood, tissues and organs of the body. The condition is characterized by fluid retention in the legs and ankles, nausea, vomiting, and breathing difficulty. When renal impairment persists for more than three months, it is referred to as chronic kidney disease, or CKD. It's a potentially fatal condition if not treated.
