A crooked cystostomy tube or a dislodged tube should be seen immediately and a urologist will determine if the tube needs to be reinserted or replaced; if it has been dislodged for more than 4 hours, there is little chance of reinserting it back in. A cystostomy tube is a tube that connects the bladder to the surface of the body, and is usually created by puncture or surgery in the lower abdomen to connect to the bladder. In principle, it should be replaced once a month. If the time is too long, the fistula tube on the bladder side is prone to grow stones and lead to difficulties such as extraction; if the tube is made of special material that can be left in place for a longer period of time, it should not be left in place for longer than the timeframe informed by the doctor. After the establishment of the vesicostomy tube, it is necessary to pay attention to the tube to be properly fixed, do not pull, twist, fold, pay attention to the drainage situation; if there is no liquid flow for a long time, or the liquid that comes out of the tube becomes red, cloudy, and does not get better after drinking a lot of water, it is necessary to consult the doctor in a timely manner.
