What is the reason why women can't hold urine? Because women's urethra is relatively short, generally only about five centimeters, this five-centimeter urethra has sphincter contraction to prevent urine excretion. If you can't hold urine, there is a problem with the sphincter, divided into true can't hold urine, there will be enuresis; there is urgency can't hold urine, that is, urgency. True can't hold urine is a problem with the sphincter, there is damage, or there is true incontinence. You need to go to the hospital for a urodynamic examination. If the sphincter is damaged, or the pelvic muscles are relaxed, further treatment is needed. If the urination is stimulated, the urine frequency is high, and it may be complicated with infection. If the urinary system infection is cured, this situation will be resolved.
