It is generally not recommended for the average patient to change their own catheter, but after specialized training, it is entirely possible to do so on your own.
A catheter is a tube that is inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a bladder near the end of the catheter head that holds the catheter in place so that it does not easily come out of the bladder, and the drainage tube is connected to a bag to collect the urine.
If patients are not trained to change the catheter themselves, complications such as urethral and bladder injuries or urinary tract infections may occur due to improper handling. Therefore, it is generally not recommended that patients change their own catheters. However, after professional training, it is completely possible to change the catheter by oneself after mastering the basic asepsis and changing techniques.
Patients who need to change the catheter should seek the help of doctors or nurses in time, ask others to change it or receive relevant training themselves. In daily life, patients should drink plenty of water and pay attention to the position of the urinary catheter, so as to prevent damage to the urethra due to inadvertent use of brute force resulting in catheter dislodgement.
