Abstract
Ureteral stents are hollow tubes used extensively throughout urology to facilitate drainage of the kidney and ureter. They are often used when the urinary tract becomes obstructed – typically by kidney stones. Common complications associated with indwelling ureteral stents include discomfort, infection and encrustation. New biomaterials and coatings have been used in stent design in an attempt to alleviate these stent symptoms; however, the perfect stent addressing all of these issues remains to be designed. Based on the current literature, biodegradable and drug-eluting technology appear to be the future of ureteral stent design. This chapter focuses on discussing past and present biomaterials used in ureteral stent design as well as the direction that ureteral stent design is currently taking.
