When A Kidney Stent Is Used
If you have a urinary blockage, you may have to also have a kidney stent. It is a hollow tube made of flexible plastic and it is placed between the kidney and the bladder inside the ureter. This allows a person to urinate even if there is a blockage. The kidney stent is designed to stay in this area because of the way it is constructed.
On both sides of the kidney stent, coils can be seen. They are placed there so that the stent stays in place during activities. Since they are made with a soft flexible plastic, they can move with the body causing no discomfort. The most common kidney stent is around 9 inches long but they do come in various sizes for each individual problem.
The bladder, urethra, kidneys and ureters make up the urinary system. The kidney holds the urine and it travels to the in a tube called the ureter. When the bladder is full a person will have an urge to use urinate and it eventually passes through the urethra and out of the body. When there is a blockage in ureter a kidney stent is used. They are a few reasons why this can happen.
Kidneys stones can break into smaller pieces and block the ureter. Although this is an extremely painful condition, these stones will eventually pass and no further medical treatment is needed. But in rare cases, a doctor may choose to do a shock wave lithotripsy to remove the kidney stones.
The ureter can become narrow because of scarring to the area. This is called a puvli ureteric junction. A doctor will have to perform tests to see if there is a full or partial blockage. If it is partial blockage, it is easily treated. But with full blockages surgery might be needed to correct the problem.
After surgeries are performed to this area, it isn’t rare for a doctor to cause this blockage for medicinal purposes. He may choose to leave an instrument inserted into the ureter or the kidneys until the area fully heals.
Other more severe illness that can cause blockage in the urinary system are cancerous tumors or diseases of the prostrate. Either of these conditions requires medical help immediately and surgery might be needed as well as chemotherapy and radiation to correct the problem.
Obstructions in the ureter can also be a serious problem. When this happens urine builds up in the kidney and stagnates. This can damage the kidneys and also cause an infection and this can worsen the symptoms. In the worst cases, the sufferer can experience complete kidney failure. So any kind of blockage can cause permanent damage to the kidneys if left untreated.
Usually a kidney stent is used until surgery can be done to correct the blockage. This gives the patient relief until the problem can be corrected and lowers the risk for getting an infection. If they are no clear answers right away for the blockage, the stent will be used until a diagnosis is made. The kidney stent is also used after surgery on the ureter, until the area is fully healed and the ureter is healed enough to function normally.
A kidney stent can sometimes be uncomfortable and painful. Some patients experience an urgency to urinate and a small amount of blood may also be seen in the urine. Women can have problems with occasional incontinence as a result of the stent and other patients complain that they are aware of the stent at all times because it causes pain. Luckily, the kidney stent is only temporary and usually they are removed in a few weeks.
