Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

Rapid Decrease

Acute renal failure (also referred to as acute kidney injury) refers to a rapid decrease in renal function; it is reflected by an increase in blood urea and creatinine and is often associated with oliguria (a urine volume of less than 400 ml/24 hours). It usually develops over days to weeks. Acute kidney injury has been variously classified, but the current classifications are based on the glomerular filtration rate (or creatinine), looking at changes from baseline, and the presence of oliguria or anuria. The potential etiologies of acute kidney injury are usually considered anatomically under the headings prerenal, renal (intrinsic), and postrenal. This chapter looks at the etiology, symptoms, clinical features, demographics, complications, diagnosis, and treatment of acute kidney injury.
