A kidney stent is a medical device that is used to reduce the size of the blood vessels in the kidney. As a result, the urine will be unable to flow through the ureter. As a result, there is an increase in the urinary load and the patient suffers from various kidney-related symptoms such as loss of urine, blood in the urine, pain in the abdomen and so on. The condition can also lead to various kidney diseases and eventually to death.
Usually, the kidney stones pass through the urethra and stay in the kidney until they are broken down. If the stones are small, the stone will pass out without any problem. But if they are large or hard, then the kidney stones remain in the kidney and start to block the passage of urine. This blockage prevents the urine from being able to move through the kidney and the patient starts suffering from kidney related symptoms. One of the best ways of removing these stones is to use the kidney stent.
There are several ways in which the kidney stent removal is carried out. Generally, the procedure is done under the supervision of a urologist. When a stone is blocking the passage of urine, then it may need to be manually shifted through the urethra. The process is usually carried out manually by pushing the blockage through the urethra until it is removed. In some cases, the stone might not be able to be moved by manual pushing and might require ultrasound to remove it.
Once the stone has been removed through ultrasound, then the device is placed in the urinary tract and left for some hours. During the time that the stent is in place, the kidney stones fall out gradually by themselves. This means that the entire process is a very slow one. In order to prevent the formation of kidney stones in the future, then it is important that such patients are diagnosed with kidney stent before they undergo such procedure.
There are many advantages of using the stent. For one, it can prevent the formation of kidney stones. It also works on the principle of strengthening the walls of the urinary tract so that stones cannot build up again in the future. Once the stent is inserted into the urinary tract, the urine is prevented from moving out through the opening. This is a very useful device to prevent kidney stones from forming.
Unlike other options, the stents that are used to keep the kidney stones away do not cause any pain to the patient. There are no reports of incidences of infection or other complications arising from the use of stents. They are also temporary options and can be removed after some time. This also means that you will not have to go through another expensive operation.
Although most people consider using the stent when there is still a chance of the kidney stones moving out of the kidney, this is not always the case. In addition to the risk of it being ineffective against bigger kidney stones, it also increases the risk of the stones being re-absorbed into the body. Therefore, in cases where kidney stent does not dissolve all the kidney stones, it becomes necessary to use a ureteroplasty, or kidney extraction, to remove the kidney stones surgically. The ureteroplasty is also more expensive than the kidney stent.
However, in some cases, especially when the stones are too big in size to pass through the stent, and they may also be lodged at an inconvenient place (such as in the urethra), surgery may be the only option. In such cases, you need to discuss with your doctor the possible implications of kidney stent. Once you have made up your mind about going through with the operation, you can get yourself ready for it. You should not drink much before the surgery, as that can impede the process as well. Follow all the instructions carefully and do not exercise while you are waiting for the kidney stent to work.
