Leakage of urine after childbirth needs to be considered to be related to stress urinary incontinence. The main reasons for this condition to occur after childbirth are pelvic floor muscle relaxation, pelvic organ prolapse, and multiple parous deliveries. Childbirth can put a lot of pressure on the pelvic floor muscles, which can cause pelvic floor muscle relaxation or pelvic organ prolapse, resulting in stress urinary incontinence. When this clinical condition occurs, patients need to go to the hospital for urodynamic and routine urine examinations to clarify the diagnosis. Once diagnosed with stress urinary incontinence can be treated with medication, such as taking Midodrine, etc., and usually insist on exercising the pelvic floor muscles.
