To develop a portable dynamic bladder pressure monitoring device for facilitating the monitoring of bladder detrusor pressure in patients with neurogenic bladder (NB) caused by spinal cord injury and further compared the effect with traditional urodynamics devices.
Portable dynamic bladder pressure monitoring device was implemented by software and hardware. The hardware was mainly composed of seven parts, such as micro liquid pressure sensor, electric bridge amplifying circuit, clock module, SD card storage circuit, liquid crystal display circuit, touch circuit, controller circuit and so on. The main program of the software included system initialization, data acquisition, storage, display, alarm, etc. A total of 45 patients with neurogenic bladder caused by spinal cord injury were enrolled in the study. Detrusor pressure was measured with the portable device and traditional urodynamics device.
The test-retest reliability of the portable device was modest in two times test (intra-class correlation coefficient (ICC) = 0.852), no significant difference was found in the results of volume perfusion evaluation between our device and conventional urodynamic (each P > 0.05).
The portable dynamic bladder pressure monitoring device is conducive to the dynamic monitoring of bladder pressure in patients with neurogenic bladder caused by spinal cord injury.
研发一种便携式动态膀胱压力监测装置，以方便对脊髓损伤所致神经源性膀胱（NB）患者的膀胱逼尿肌压力进行监测，并进一步将其与传统尿动力学装置的效果进行比较。
便携式动态膀胱压力监测装置通过软件和硬件实现。硬件主要由微液体压力传感器、电桥放大电路、时钟模块、SD卡存储电路、液晶显示电路、触摸电路、控制器电路等七个部分组成。软件的主程序包括系统初始化、数据采集、存储、显示、报警等。本研究共纳入45例脊髓损伤所致神经源性膀胱患者。使用便携式装置和传统尿动力学装置测量逼尿肌压力。
便携式装置在两次测试中的重测信度适中（组内相关系数（ICC）=0.852），我们的装置与传统尿动力学在容量灌注评估结果上无显著差异（各P>0.05）。
便携式动态膀胱压力监测装置有利于对脊髓损伤所致神经源性膀胱患者的膀胱压力进行动态监测。
