Abstract:
Objective To explore the consistency between morning and 24-hour urinary biochemistry/creatinine.Methods Totally 60 patients with urinary system lithiasis hospitalized in a Class Ⅲ hospital from February 2017 to April 2018.The calcium,sodium,potassium,magnesium,phosphorus,chlorine,uric acid,urea nitrogen and creatinine in their morning and 24-hour urine was tested.Meanwhile,a total of 29 healthy student volunteers were selected as a control group.Results After calibration and log transformation of morning and 24-hour urinary biochemistry/creatinine,the correlation coefficient r in the healthy group was 0.58-0.77 (P＜0.05),while the r value in the lithiasis group was 0.07-1.04 except the log of urea nitrogen and creatinine (P＜ 0.05).According to the Bland-Altman consistency analysis,the consistency of the log of uric calcium/creatinine in the healthy group ranged from -0.35 and 0.19,while that in the lithiasis group was -0.53-0.82;the log of uric potassium/creatinine in the healthy group was -0.35-0.57,while that in the lithiasis group was -0.53-0.66;the log of uric chlorine/creatinine in the healthy group was -0.33-0.86,while that in the lithiasis group was -0.90-1.04;the log of uric sodium/creatinine in the healthy group was -0.38-0.96,while that in the lithiasis group was -0.73-0.97;the log of urea nitrogen/creatinine in the healthy group was -0.17-0.39,while that in the lithiasis group was -0.70-0.81;the log of uric acid/creatinine in the healthy group was -0.15-0.48,while that in the lithiasis group was -0.29-0.37;and the log of urea magnesium/creatinine in the healthy group was -0.28-0.60,while that in the lithiasis group was -0.36-0.57.Conclusions The consistency of uric phosphorus,urea nitrogen and uric acid is good in the healthy group,while the consistency of uric potassium,chlorine and acid is good in the lithiasis group;the consistency of other indicators is not good.Morning urinary biochemistry shows a better predictive value of lithiasis risks than 24-hour urinary biochemistry.
