In addition to pseudoproteinuria, we should also pay attention to whether it is caused by hypertension and kidney disease during pregnancy. 1. pseudoproteinuria: because the female urethra is short and adjacent to the vagina, pregnant women with inflammation of the reproductive tract, if the urine is not properly retained, the specimen is easily contaminated by vaginal secretions, which can lead to misdiagnosis of proteinuria. It is recommended to take urine specimens for examination in the middle segment of urine; 2. Hypertensive disease: in patients with hypertension, the glomerular filtration rate decreases, plasma protein is leaked out by the glomerulus, and elevated blood pressure with elevated urine protein can occur. In mild cases, there is no symptom or mild dizziness, mild elevation of blood pressure with edema or mild proteinuria; in severe cases, eye blur, nausea, vomiting, persistent right upper abdominal pain with marked elevation of blood pressure, increased proteinuria, marked edema, and even coma and convulsions. If the random urine protein exceeds (++), hospitalization should be performed to check the 24-hour urine protein quantification and determine the severity of the condition. If the condition is too serious, the pregnancy needs to be terminated; 3. Kidney disease: increased metabolism in the body and increased systemic blood volume during pregnancy will increase the burden on the kidneys, and patients with kidney disease will have elevated urine protein, which requires further examination of plasma microglobulin, timely treatment after clarifying the cause, and if necessary, termination of pregnancy. In addition, pregnant women should get enough sleep during pregnancy, pay attention to a balanced diet, take appropriate calcium supplements, and reduce the intake of protein-rich foods during the illness. Regular maternity checkups and timely medical treatment if there is any abnormality.
