Comparison of protein amount in 24-hour urine and protein/creatinine rate in spot urine of preeclamptic pregnant women

Objective: To compare protein amount in 24-hour urine and protein/creatinine rate in spot urine of preeclamptic pregnant women. Methods: The study included 45 pregnant women with preeclampsia whose 24-hour urine protein and protein/creatinine rate in spot urine were checked in the Perinatology Clinic of Istanbul Kanuni Sultan Süleyman Training and Research Hospital between January 2015 and December 2015 and 45 pregnant women without preeclampsia as control group who were followed up in obstetrics polyclinics. Systolic and diastolic blood pressure values, protein amount in 24-hour urine, protein/creatinine rate in spot urine, delivery week, delivery type, birth weights and 1-minute and 5minute APGAR scores of pregnant women in both groups were recorded and their correlation with protein/creatinine rate in spot urine were evaluated. Results: When protein amounts in 24-hour urine and protein/creatinine rate in spot urine of patients were compared, significant correlation was found between 24-hour urine protein and protein/creatinine rate. It was also found that there was no significant correlation between protein/creatinine rates and blood pressure values, delivery week, birth weight and APGAR scores. Conclusion: We found that there was a significant correlation between protein amount in 24-hour urine and protein/creatinine rates in spot urine. Therefore, in acute and emergency cases where proteinuria cannot be checked in 24-hour urine, protein/creatinine rate in spot urine can be useful to evaluate proteinuria.
