Many women experience urinary incontinence after childbirth, and the severity varies from person to person. The causes of postpartum urinary incontinence include the following aspects. First, during pregnancy, the enlargement of the uterus can significantly press on the female pelvic floor, causing damage to pelvic floor function. Second, for women who have a vaginal delivery, the fetus needs to pass through the vagina. This process can further exacerbate damage to the female pelvic floor. These factors together can lead to pelvic floor dysfunction, resulting in conditions like uterine prolapse, bladder prolapse, and even urinary incontinence. For postpartum urinary incontinence, interventions such as Kegel exercises and electrical stimulation therapy should be used together to alleviate clinical symptoms and minimize impact on daily life. If conservative treatments are ineffective, pelvic floor repair surgery should be considered.
