Summary

We detected a special plastic, which is stable in an acid environment and dissolvable in a basic one. Our preliminary in-vitro results show that the tested material therefore seems principally designed for developing biodissolvable stents for temporary urinary diversion out of the upper urinary tract. Stableness and dissolution could be steered by manipulating the pH.

Zusammenfassung

Es ist gelungen, ein Polymer zu entdecken, welches – maschinell extrudierbar – im sauren Milieu formstabil bleibt und sich im basischen Milieu auflöst. Der getestete Kunststoff bietet die prinzipiellen Voraussetzungen zur Weiterentwicklung bioerodierbarer Schienensysteme zur temporären Harnableitung. Dabei scheint der Auflösungszeitpunkt, der in vitro innerhalb 48 h abgeschlossen ist, über eine medikamentöse Beeinflussung des pH-Wertes steuerbar.
