The examination methods for female UTIs are: 1. Physical examination, which means that the patient needs to be placed in a lithotomy position to fully expose the external genital area and be examined by a professional doctor. The test includes whether the urethral orifice is red and swollen, whether there is urethral discharge, whether there is local erosion or exudation, etc. 2. Laboratory tests, such as routine urinalysis, clean middle urine culture test or retention of urethral secretions for bacterial culture test, through the above-mentioned tests to further clarify whether there is an infection and what is the pathogenic bacteria of the infection. 3. The presence of local morphological changes in the urinary tract, such as the presence of urethral congestion, edema, hydronephrosis, bladder chambers, trabecular hyperplasia, urethral filling defects and other lesions, can be further investigated through imaging, such as urological ultrasound, urography or urethroscopy, to determine the presence of urethritis or its causes of urethral infection.
