The onset of stress urinary incontinence primarily refers to the phenomenon where a sudden increase in abdominal pressure during activities such as laughing, sneezing, lifting heavy objects, or jumping rope causes a small amount of urine to leak from the urethra. The main cause of stress urinary incontinence is due to the relaxation of the detrusor muscle, commonly seen in women who have had multiple vaginal deliveries. Treatment for this condition should be based on the severity of the incontinence. For mild incontinence, it can be improved through functional exercises of the detrusor muscle and pelvic floor muscle training. For moderate to severe stress urinary incontinence, surgical treatment is recommended.
