Experimental study of erosive possibility of ultrasound exposure in rehabilitation of nephrostomy catheters

Abstract

This article assesses the effectiveness of invasive acoustic treatment in the drainage of external urological catheter (nephrostoma). The description of the developed research stand is given, the results of scanning electron microscopy on the device «JCM–5700» are given, the percentage of remote obstruction is determined by the results of weighing samples before and after ultrasonic exposure. It is shown that a short ULTRASONIC effect on the liquid medium in the encrusted catheter allows to remove up to 60 % of contaminants.
