Renal Stent Placement

Renal stent placement is done to treat blockages in the ureter. A renal stent is held at place with coils that are placed on both its ends. When it is felt by a doctor that a patient needs a renal stent placement then a complete medical image study is conducted on the patient. This imaging study is done with the aim of looking at the blood vessels which surround the kidney. If the doctor feels the need then an angiogram might also be conducted. In an angiogram tracer dyes are used. With the use of these tracer dyes the path of blood flow is determined.

On the day of the renal stent placement, the patient is laid on the x-ray table and an intravenous line is started. This is done in order to allow easy flow of drugs and fluids that are administered. A member of the angioplasty team administers local anesthesia on the area. The next step is making of a small incision. This is done so that the thin, flexible catheter can be inserted in it. Using x-ray guidance the catheter is threaded through the arteries till it reaches the area in the artery where there is the renal blockage.
Renal Stent Placement, Renal Stent Placement Procedure
There is a tiny balloon at the tip of the catheter. This is inflated so as to push the accumulated plaque towards the walls of the artery and this allows the free flow of blood through the blood vessel. The catheter is used as the delivery medium and then an expandable stent made of wire mesh is placed into that area of the artery which was previously blocked.

A renal stent placement can be quite painful. Anesthesia is administered to make the patient comfortable during the process. After the renal stent placement the patient needs to be extra careful. Before renal stent placement the doctor must be aware of the whole medical history of the patient. This is to make sure that there are no conditions in the patient which would make renal stent placement risky. The patient should be given clear instructions by the doctor about what to do and what not to do. Special care and medications are required after renal stent placement. For instance, the patient needs to take special medication to prevent the formation of blood clots around the stent in the artery. The patient should clearly know everything about such medications. The patient should have complete information about which type of stent is being used by the doctor.

Regular examination of the patient and the stent is very essential after renal stent placement. Such checks are done to make sure that stent is held fixed at its place and has not drifted. If there is any shift in the renal stent then it can cause complications.

**Renal stent is a wire-mesh tube which is expandable. It can be placed in an artery to prevent the blood vessel from narrowing. It helps in preventing lower blood flow to any organ or tissue that the artery feeds.
