High routine urine leukocytes in late pregnancy need to be combined with self-conscious symptoms, which may be caused by a sampling error or by a urinary tract infection. If the pregnant woman is not experiencing symptoms such as burning and pain in the urinary tract, it may be due to leukocytes being mixed into the urine while the pregnant woman was retaining the urine specimen. To further clarify the diagnosis, consider retaining clean mid-stream urine and re-examining it for laboratory tests. If the re-examination still shows elevated leukocytes in the urine, but the pregnant woman has no other clinical symptoms, consider it as asymptomatic leukocyturia. You can reduce the symptoms of urinary tract infection by drinking more water to make sufficient urine and increasing the frequency of urination for the purpose of natural bladder flushing. If the routine urine leukocytes are high in late pregnancy and the pregnant woman also has frequent urination, painful urination, lower abdominal discomfort or hematuria in the naked eye, it is usually due to an acute urinary tract infection. In this case, you should go to the hospital in time to have urine bacterial culture and urinary ultrasound examination to make a clear diagnosis, and you can choose appropriate anti-inflammatory drugs for treatment under the guidance of the doctor. In addition, in the late pregnancy, pregnant women should pay attention to keep the vulva clean and dry, wash the vulva with warm water every day, bathe regularly, change underwear regularly, maintain a relaxed mood, regular life, reasonable diet, appropriate activities, regular pregnancy checkups, and should also pay attention to the prohibition of sexual intercourse in the late pregnancy.
