Chronic kidney disease (CKD) has a high prevalence in the elderly population. Almost half of the population reaches moderate impairment (CKD 3) by 65 years of age. This article describes CKD staging in the geriatric population and several common clinical presentations of renal disease. ⋯ Geriatric patients are at an increased risk for renal dysfunction from many causes. Some causes are inherent with aging, such as gross structural and cellular changes, decrease in physiologic function, and lowered vascular compensatory reserve. Exposures, including medications and diagnostic testing, are contributors to acute kidney injury.
