Situation analysis on kidney damage of the 1088 elderly health examination people / 中华老年医学杂志

ABSTRACT

Objective To analyse the kidney damage situation of the elderly health examination people,and identify its characteristic.Methods A cross-sectional study was held which enrolled 1088 elderly health examination people.Urine routine,random urine albumin/creatinine ratio (ACR),serum creatinine,urea nitrogen were detected by biochemical analyzer,and estimated glomerular filtration rate (GFR) with CKD-EPI formula.Kidney structure change was examined by Color doppler ultrasound detector.Results The prevalence of hypertension,hyperlipemia,diabetes mellitus was 61.5％,62.1％,11.6％,respectively.The abnormal detection rate of urine routine was 19.0％,including 2.6％ proteinuria,14.1％ hematuresis and 5.4％ leucocyturia.The abnormal detection rate in the people with was higher than those without (P＜0.01).However,the albuminuria detection rate with random urine ACR was 25.1％,obviously higher than that of urine routine (P＜0.01).The ultrasound results showed that 6.8％ of the total were examined with elderly characteristic kidney change,the proportion of renal cyst was the highest,accounted for 21.8％.70.7％ of all people were in the level of eGFR more than 60 ml· min-1 · 1.73 m-2.The level of eGFR＜60 ml· min-1 · 1.73m-2 in the people with was higher than those without (P＜0.01).eGFR was declined with age.When age increased every 10 years,eGFR was decreased 7 ml · min-1 · 1.73 m-2.Conclusions No matter in structure or function,the elderly people's kidney damage has its characteristic.We should make it clear to correctly diagnose and cure elderly kidney disease.
