Mild postpartum incontinence, most patients can recover on their own in about 1 to 3 weeks after delivery, and can do without special treatment. Some patients need to strengthen the pelvic floor muscle groups after delivery to improve the exercise, such as lifting anal exercise, the specific method is, deep inhalation, lift the anus to hold for 5 seconds, and then relax, 15 ~ 20 times in a row as a group. Exercise about 20 sets per day. Persist for about 3 months will have significant improvement. If there is a serious perineal tear, urethral injury, bladder vaginal leakage, etc., then a catheter should be left in place to drain the urine, and then the necessary surgical treatment should be carried out, with the help of a pelvic floor training device to help recover after surgery.
