| Sumario: | Ureters are long tubular structures that connect each kidney to the bladder. Various diseases, and medical conditions such as tumors and ureteral stones, can cause blockage of the ureters, preventing the flow of urine out of the kidneys and into the bladder. This can lead to hydronephrosis, a potentially life-threatening condition. Ureteral stents are tubular medical devices that can be inserted into a ureter to maintain an open pathway and allow drainage of urine from the kidney to the bladder. Ureteral stents are manufactured in several diameters and lengths, and are made of various polymeric materials. The stents are typically intended to remain in the patient for up to 30 days and are then removed when there is no blockage remaining after the ureter has healed. The use of ureteral stents requires two hospital-based procedures: insertion and retrieval. Both are endoscopic procedures that involve twilight sedation and a local anesthetic, and both generate a hospital bill. Patients must also miss a day of work after each procedure to recover from the anesthesia. If the retrieval procedure could be eliminated, then it would reduce the cost of using a stent, the risks associated with anesthesia, and the need for patients to miss work. This case study presents the details of a project created to explore ways to eliminate the retrieval procedure. A new stent made from a unique, patented, biodegradable terpolymer material was developed to provide the mechanical and material properties required to create a stent that would dissolve in the body after a few weeks. The new stent was expected to reduce the cost of stent use, save the patient time, and reduce the associated anesthesia risk. |
