Bladder water injection test

The bladder water injection test is an auxiliary examination method to check whether the bladder detrusor function is normal. The bladder water injection test is a common diagnostic method for urinary bladder rupture. The conventional method is to inject 100 to 300 ml of sterile physiological saline into the bladder through a catheter and then withdraw it after 1 to 2 minutes. If injected, the bladder is ruptured. Through this examination, the corresponding symptoms can be judged.
