Ureteral stent tubes can usually be left in place for 2 to 4 weeks, usually no longer than 3 months, and certain special materials can be left in place for 6 months or even longer.
The length of time a ureteral stent can be placed depends on the type of disease, the severity of the disease, and other factors, and will vary from person to person. Ureteral stents are usually left in place for 2 to 4 weeks after ureteral stone surgery, and for ureteral strictures they are usually left in place for a longer period of time, up to 2 to 3 months, and may need to be replaced, as prescribed by the doctor.
When a ureteral stent tube is placed in the body, one end is placed in the kidney and the other end is placed in the bladder area, which can have a supportive drainage effect on the ureter. It helps to smooth the drainage of urine after the procedure. If the ureteral stent is placed for a longer period of time, it is easy to form stones locally, leading to blood in the urine as well as back pain, so the ureteral stent tube needs to be removed periodically.
