About Kidney Diseases
RIA Endovascular’s interventional radiologists provide a variety of kidney and urologic treatments for those with renal and urologic conditions, including dialysis catheters, nephrostomy tubes and ureteral stents.
For a patient whose kidneys have failed, venous access, or access to the blood system, must be established and maintained for dialysis treatments. Placement of a chronic dialysis catheter (CDC) can provide this access. The catheter is placed in one of the large veins. A common site is superior vena cava or SVC. You can learn more about the procedure, which is performed by an interventional radiologist, on our kidney interventions page.
A nephrostomy is a tube put into the kidney. The urine from a normal kidney drains through a narrow tube, the ureter, into the bladder. When a stone or a blood clot blocks that tube, the kidney can be damaged. It may be possible to drain the urine by inserting a fine plastic tube, called a catheter, through the skin and into the kidney under local anesthetic. The urine drains from the kidney into a collecting bag outside the body. Learn more about the procedure itself on our kidney interventions page.
The ureters are the tubes that connect each kidney to the bladder. When these tubes become blocked, it is necessary to place a stent to improve urinary drainage from the kidney(s). Learn more about this procedure on our kidney interventions page.
