摘要: 尿动力学检查可以再现患者的下尿路症状并且能客观解释患者的膀胱问题。目前,临床最常用的尿动力学测压导管是液体传导导管,由于经济、卫生等优点,受到广泛认可。然而,液体传导导管中气泡及患者活动会影响信号传导质量。气体传导导管操作简便易行,测量值不受气泡和患者活动的影响,已逐渐在某些地区开始用于尿动力学测压。气体传导系统与液体传导系统在很多方面存在差别,在流体力学原理、调零方法和操作细节等方面的差异直接或间接影响测压结果。国内外对气体传导系统的研究还不完善。本文综述国内外研究现状,从基本构造、发展沿革、零压力点设置、频率响应、膀胱测压、尿道压力描记、压力值转换算法和检查后的感染发生率等方面进行分析。

Abstract: Urodynamics is able to reproduce the patient's lower urinary tract symptoms and to explain patient's bladder problems objectively. Currently, the most commonly used urodynamic manometry catheter is water filled catherters, which is widely recognized due to its economic and healthy advantages. However, air bubbles and patient's activities can affect the quality and speed of signal transduction, interfering the explanation of the pressure results. The air-filled catheters are easy to operate, and the measures are unaffected by air bubbles and patient's activities, which have gradually begun to be used in urodynamic study in some areas. However, there are several differences between them in terms of fluid mechanics principle, zero set and detailed operations which directly and indirectly lead to the different pressure results. The researches on air-filled catheters at home and abroad are still not perfect. This article gave a detailed comparison between them based on the present studies from the following aspects: the essential structure, the developing history, the fluid mechanics principle, the zero pressure point setting, the frequency response, the cystometrogram, the urethral pressure profile, the conversion algorithm, and the urinary tract infection after the investigation, etc.
