摘要

介绍。输尿管支架表面的结痂和生物膜的形成仍然是上尿路内引流最重要的并发症。为了对抗这些并发症,进行了许多研究。缺乏解决这一问题的办法会影响治疗的最终结果和经济损失。物理方法对输尿管支架的影响问题,特别是体外超声声暴露的使用仍然存在,有希望但很少被报道。研究目的:目的:探讨低频超声调幅信号体外声暴露在输尿管支架上的最佳应用点。材料和方法。最初的装置设计好了。其主要工作原理是产生两种模式的振幅调制超声信号:脉冲和永久。性成熟的杂种狗是一种实验动物。输尿管支架通过剖腹和膀胱切开放置。术中,根据先前指示的地形和解剖标志,将开发的装置的发射器应用于动物的皮肤。同时,通过开腹切口将超声噪声分析仪应用于输尿管的适当水平。在仪器的两种工作模式下,对超声强度指标进行了三次测量。脉冲模式:输尿管上三分之一处,沿腋后线超声强度最高(123.67 dB)。对于输尿管中三分之一处,经腋后线处超声强度最佳(115 dB)。输尿管下三分之一沿腋中线超声强度最高(113.67 dB)。永久模式:输尿管上、中、下三分之一超声强度沿腋后线为最佳,分别为118.67 dB、117 dB、116.67 dB。然而,存在过热效应,表现为动物皮肤充血和高热,仪器在永久模式下工作时,束肌收缩,这可能导致热烧伤和对该程序的不耐受。设备功能的脉冲模式是最安全的。输尿管上三分之一和中三分之一的器械发射器的最佳施放点为腋后线,输尿管下三分之一的器械发射器的最佳施放点为腋中线。

Extracorporeal ultrasound exposure by the low-frequency acoustic amplitude-modulated signal on a ureteral stent for preventing its incrustation: experimental determination of optimal application points
Introduction. Incrustation and biofilms formation on the surface of ureteral stents are still the most significant complications of internal drainage of the upper urinary tract. There are much researchers conducted to combat these complications. The lack of a solution to this problem affects the ultimate results of treatment and economic losses. The issue of impact by physical methods on the ureteral stent, particularly the use of extracorporeal ultrasound acoustic exposure remains, promising and poorly covered.Purpose of the study. To determine the optimal application points of extracorporeal acoustic exposure by the low-frequency ultrasonic amplitude-modulated signal on a ureteral stent in an experiment.Materials and methods. The original device was designed. The main principle of its operation is the generation of an amplitude-modulated ultrasonic signal in two modes: pulsed and permanent. A sexually mature mongrel dog was an experimental animal. The ureteral stent was placed by laparotomy and cystotomy. Intraoperatively, the emitter of the developed device was applied to the skin of the animal, according to the previously indicated topographic and anatomical landmarks. At the same time, an ultrasonic wave noise analyzer was applied through the laparotomy wound to the appropriate level of the ureter. Measurements of ultrasound intensity indicators were performed three times in two operating modes of the device.Results. Pulsed mode: for the ureteral upper third, the highest ultrasonic intensity (123.67 dB) was achieved along the posterior axillary line. For the ureteral middle third, the best ultrasound intensity (115 dB) was obtained by the posterior axillary line. For the ureteral lower third, the highest ultrasound intensity (113.67 dB) was noted along the middle axillary line.Permanent mode: the best ultrasonic intensity in the projection of the ureteral upper, middle, and lower thirds was achieved along the posterior axillary line and was 118.67 dB, 117 dB and 116.67 dB, accordingly. However, there was an excessive heat effect, manifested by hyperemia and hyperthermia of the animal's skin, fascicular muscle contractions during the instrument functioned in the permanent mode, which can potentially lead to thermal burns and intolerance to the procedure.Conclusion. The pulsed mode of the device function is most safe. The optimal application points of the instrument emitter for the ureteral upper and middle thirds is the posterior axillary line, and for the ureteral lower third is the middle axillary line.
