Urodynamic incontinence: It is common in nervous system diseases, such as cerebral infarction and waist trauma, which leads to nervous system damage and the brain's control over the bladder is weakened. Female urethra is short and urethral resistance is small, which is easy to cause urge urinary incontinence;
2. Stress urinary incontinence: related to age, childbirth and other factors. Pelvic floor muscles are relaxed, and the ability to control urine is weakened, which eventually leads to stress urinary incontinence.
