Urethral insertion in women is usually painless. The female urethra is 3 to 5 centimeters long and is short and straight, and the catheterization procedure is usually performed under local anesthesia. Friction between the catheter and the mucous membrane of the urethra may cause slight discomfort, but usually no severe pain. Before inserting a urinary catheter in a girl, the healthcare personnel concerned will sterilize the perineal skin, put on sterile gloves and perform aseptic operation. Generally, there is no significant pain. In addition, do not leave the catheter in place for too long, as this may lead to urinary tract infections. Keep the perineal skin clean during urinary catheterization. During urinary catheterization for girls undergoing surgery, you only need to properly cooperate with your healthcare provider and relax to complete the entire process. If there is any discomfort after the insertion of the urinary catheter, promptly inform the health care personnel to deal with it to avoid any adverse consequences.
