ABSTRACT: Several studies argue that an ideal biomaterial for
urinary catheters is utopian. Based in literature review it seems to be true.
However, research advances: the biomaterial itself, new designs, new coatings,
associated drugs, etc. Once implanted and interacting with urine, two old
problems persist: encrustation and bacterial colonization. In this context, an
extracellular product from bacterial synthesis on sugarcane molasses biomaterial has been studied
in several experimental and clinical studies. Based on its high
biocompatibility, the aim of this study is to evaluate its performance in an in vivo model as an endourologic
prosthesis implanted in the bladder of Wistar rats. We evaluate physical,
chemical and biological phenomena in comparison to an already
established biomaterial, polyurethane. Even though it is not a finished
product, the sugarcane biopolymer presented similar performance compared to
polyurethane in several analyzed parameters and has an important
characteristic: low cost.
