Abstract

um stent urinário inclui extremidades para implantação no rim e bexiga, respectivamente, que não são coplanares. a extremidade da bexiga do stent inclui uma ranhura luminária, coberta por uma manga de material mais suave do que o restante do stent, permitindo que a urina tenha pressões suficientes para passar do stent, entre o stent e a manga. a extremidade da bexiga do stent adapta sua forma de acordo com mudanças respiratórias no comprimento do stent. esta mudança da forma também previne ou reduz a dor relacionada ao stent.
