How often does the indwelling catheter change?

How often the indwelling catheter is replaced depends on the actual situation of the patient. Most patients need to replace it every 2~4 weeks. Too long may cause excessive crystallization in the ureter, or even cause bladder stones. Too short a time will frequently stimulate the urethra, stimulate the bladder, and easily cause damage and urinary tract infection. Pay attention to the observation during the catheter. If the catheter drainage is not smooth, it needs to be replaced once every two weeks. If the catheter drainage is smooth, it is also possible to replace it once every four weeks. During the indwelling catheter, the patient needs to drink more water, which is conducive to preventing urinary salt crystals from adhering to the inner opening of the catheter and prolonging the retention of the catheter.
