What is a Kidney Stent?
I'm a visual person so I found this illustration to help demonstrate more about a kidney stent.
In patients who have, or might have, an obstruction (blockage) of the kidney, an internal drainage tube called a ‘stent’ is commonly placed in the ureter, between the kidney and the bladder. This is placed there in order to temporarily relieve the obstruction.
How long will the stent stay in the body?
There is no hard and fast rule about this. The stent has to be kept in place as long as necessary, i.e. until the obstruction is relieved. This depends on the cause of obstruction and the nature of its treatment.
In the majority of patients, the stents are required for only a short duration, from a few weeks to a few months. However, a stent in the right position can stay in for up to three months without the need to replace it. When the underlying problem is not a kidney stone, the stent can stay in even longer. There are special stents, which may be left in for a much longer time. Your urologist will tell you how long he expects your stent to remain in place.
