Abstract

Degradable ureteral stent not requiring redo procedure for removal is an important issue in modern urology. This device could solve the problem of «forgotten stent» often leading to long-term complications. The authors describe the prototype of biodegradable ureteral stent based on poly(L-lactide-co-ε-caprolactone) and present the first results of its testing. Characteristics of synthesized polymer meet the requirements in medicine. Tests of rod-shaped stent prototypes showed that material has sufficient strength and elasticity. Analysis of stent degradation in artificial urine environment at 37 ºC showed that it retains strength for at least 2 weeks. No suppression of cell growth confirms no cellular toxicity. New material based on poly(L-lactide-co-ε-caprolactone) is promising for development of experimental samples of biodegradable ureteral stents and further in vivo testing.
