If a woman has more leukorrhea, it may affect the results of the urine routine, because the vaginal opening and urethral opening are very close to each other, and if there is more leukorrhea, it may be mixed into the urine when the urine specimen is taken, thus leading to abnormal test results. Therefore, if a woman does not have symptoms of urinary tract infection, but a routine urine test indicates a large number of white blood cells and purulent cells in the urine specimen, it is recommended that a gynecological examination and a white belt routine be performed again to see if the contamination is caused by the white belt. It is recommended to wash the vulva with water before the examination and then take the interrupted urine for the specimen, so as to avoid the contamination of the leukocytes as much as possible, and also if the vaginal inflammation is very serious, it can cause urinary tract infection through cross-infection. So there are many women with gynecological diseases who also experience frequent and painful urination and need to pay attention to hygiene and active treatment.
