A high number of squamous epithelial cells in the urine of a pregnant woman after a routine urine test may indicate the presence of inflammation in the urinary tract of the woman, such as a urinary tract infection, or due to nephritis. However, it may also be caused by the flow of vaginal secretions into the urine and contamination of the urine later. This is because during pregnancy, the leukorrhea secretions of pregnant women will be significantly higher than in the non-pregnant state, so when a routine urine test is performed, the squamous cells in the urine may be elevated due to the natural discharge of leukorrhea secretions from the vagina into the urine. Because a large number of cervical squamous epithelial cells are shed within a woman’s leukorrhea secretions, a pregnant woman who has a routine urine test suggesting elevated squamous epithelial cells alone often does not have any diagnostic significance and can be rechecked again after an interval of half a month without special treatment.
