Postpartum bedwetting may be caused by damage to the pelvic floor muscles during labor, or damage to the urethral sphincter. Postpartum bedwetting is mostly seen in women who have a normal delivery. During labor, the fetus overstretches and expands the pelvic floor muscles and ligaments, leading to relaxation of the pelvic floor muscles, and dysfunction of urinary storage and voiding, which results in uncontrolled urine that flows out of the body on its own. Through the contraction and diastole of the urethral sphincter, the excretion of urine can be controlled. When some women are in labor, due to the extrusion of the urethra by the fetus, or excessive force during labor, resulting in damage to the urethral sphincter, the contraction function is limited, which will affect the normal urinary function, and postnatal incontinence occurs. If the mother has symptoms of postpartum bedwetting, it is recommended to go to the hospital for examination and repair treatment.
