BACKGROUND/AIM: The male sling operation and artificial urinary sphincter implantation are common methods for treating urinary incontinence. However, there are some drawbacks to these methods such as infection, urethral erosion, pain, inefficiency, and the technical difficulty of the operations. Here we describe a new device we have named the Turkish Continence Device (TCD) which has advantages over these other methods. The aim of this study was perform experiments with the TCD prototype in vivo and ex vivo to determine efficiency, convenience of implantation, and negative effects.
We implanted the prototype device in male goats and sheep, compressing the posterior urethra, and then fixed it by sutures on the lateral sides of the cavernosal bodies, bilaterally. Then we recorded urodynamic findings and performed urinary imaging. Additionally we measured urethral closure pressure ex vivo.
The balloon volume for efficient urethral closure pressure using the new device was under 1 mL. It compressed the urethra towards the corpus cavernosum perfectly, because the wings of the prototype device are fixed near the tunica of the cavernosal bodies on each side.
A smaller device with smaller arms/wings would be efficient for obtaining enough pressure on the urethra. Additionally, the technique for implanting the device is very simple and would likely be learned quickly.
背景/目的:男性吊带手术和人工尿道括约肌植入术是治疗尿失禁的常见方法。然而,这些方法存在一些缺点,如感染、尿道侵蚀、疼痛、效率低下以及手术技术难度大。在这里,我们描述了一种新的装置,我们称之为土耳其尿失禁装置(TCD),它比这些其他方法具有优势。本研究的目的是对 TCD 原型进行体内和体外实验,以确定其效率、植入的便利性和副作用。
我们将原型装置植入雄性山羊和绵羊体内,压缩后尿道,然后通过缝线将其固定在海绵体的两侧。然后我们记录尿动力学发现并进行尿液成像。此外,我们还在体外测量尿道闭合压。
新装置有效尿道闭合压所需的球囊体积小于 1 毫升。它将尿道完美地压向海绵体,因为原型装置的翼片固定在每侧海绵体的外膜附近。
较小的装置和较小的臂/翼片将有效地在尿道上施加足够的压力。此外,植入该装置的技术非常简单,可能很快就能掌握。
