Noninvasive Ultrasonic Sanitation of Stents for Drainage of the Upper Urinary Tract

Abstract

The goal of the study presented in this paper was to increase the effectiveness of stent sanitation with the purpose of avoiding the undesirable effects of internal drainage (in particular, incrustation). Here we suggest a new method for noninvasive ultrasound treatment and develop new equipment for more effective sanitation of ureteral stents. It was shown that ultrasound exposure of the ureteral stent is an inexpensive, efficient, and safe method for reducing salt obstruction. This method can be recommended for use as one of the therapeutic measures aimed at the prevention of obstructive pyelonephritis.
