Urinary incontinence is divided into urge incontinence, stress incontinence, true incontinence, and overflow incontinence. During diagnosis, it is first necessary to determine whether there is incontinence, which should be differentiated from residual urine. Then, based on medical history, physical examination, and whether or not there are laboratory tests, the clinical type and cause should be clarified. The medical history should pay attention to whether there are bladder irritative symptoms, history of urinary stone expulsion, and history of pelvic surgery. Pregnant patients should have a comprehensive examination of the pelvic organs, urinary reproductive system, and nervous system. When necessary, urinary tract X-ray imaging, ultrasound examination of pelvic organs, cystoscopy, and bladder manometry should be conducted.
