Ureteral stent |
摘要 |
A stent is designed to be placed within a patient's ureter to facilitate drainage from the patient's kidneys to the bladder. An elongated portion of the stent includes a length sufficient to extend substantially within the ureter from the kidney to the bladder, and defines a lumen extending therethrough. A first end portion extends from one end of the elongated portion and is adapted to assume a retaining configuration when placed substantially within the kidney. A second end portion extends from another end of the elongated portion and flares outward when placed substantially within the bladder to maintain position. The second end portion allows fluids to flow through the lumen and into the bladder and is collapsible to prevent fluid from passing from the bladder to the kidney. |
