The primary clinical manifestation of stress urinary incontinence is the leakage of urine from the urethra when sudden increases in intra-abdominal pressure occur, such as laughing, sneezing, or coughing. This condition is commonly seen in women who have given birth. It is mainly caused by the relaxation of the urethral sphincter and pelvic floor muscles after childbirth. The more childbirths a woman has, the higher the frequency of stress urinary incontinence. For mild symptoms, improvement can be achieved through pelvic floor muscle exercises. If necessary, medications such as Midodrine Hydrochloride tablets can be taken orally. For severe symptoms, surgery is recommended. (Medication should be used under the guidance of a doctor based on specific circumstances.)
