Leakage refers to urinary incontinence. Incontinence without childbearing may be caused by surgery, pelvic floor organ prolapse, and secondary to other diseases. 1. Surgery: it is usually considered that it may be in the process of hysterectomy, urethral stenosis repair and other surgeries that cause damage to the muscles, ligaments and nerves that support the bladder, which then leads to urinary incontinence. 2. Prolapse of pelvic floor organs: When the female pelvic floor organs prolapse, it will, to a certain extent, cause pressure on the urethra or cause excessive displacement of the urethra, which changes the normal structure of the pelvic floor, thus affecting the function of the bladder in storing and voiding urine. 3. Secondary to other diseases: clinically, it is mostly seen in craniocerebral tumor, cerebral palsy, multiple sclerosis, diabetes mellitus, intervertebral disc herniation, cystitis, bladder stones and so on. To summarize, there are many reasons for urinary incontinence in patients who have not given birth to children, so they need to go to the hospital in time, complete a series of relevant examinations, clarify the cause of the disease, and cooperate with the doctor for active treatment.
