直肠充盈状态对膀胱灌注感觉功能影响的研究

The study of the influences of rectal fullness on the bladder filling sensations

目的:研究直肠充盈状态对膀胱灌注感觉功能的影响。方法:12例健康志愿者分别处于直肠空虚状态和直肠充盈状态,连续行膀胱灌注测压(CMG)两次,记录不同直肠状态下的初始膀胱感觉、初始尿意感觉、急迫尿意感觉阈值。同时记录在各膀胱感觉阈值出现时的膀胱压。结果:直肠充盈状态对膀胱顺应性没有明显影响。对比直肠空虚状态下,当直肠充盈时,初始膀胱感觉、初始尿意感觉和急迫尿意感觉阈值显著性降低。结论:直肠和膀胱之间可能存在一种神经反射通路,导致直肠充盈状态可以明显影响膀胱灌注感觉阈值。在行CMG检测前,应先检查直肠是否处于充盈状态,以免影响膀胱感觉阈值测定。

Objective：To study if bladder filling sensations are influenced by the state of rectal fullness. Methods：Bladder filling sensations were evaluated during 2 consecutive cystometric studies in 12 healthy volunteers. The tests were done first with an empty rectum and then with a full rectum. The bladder pressures were recorded at the same time. Results：The state of rectal fullness had very little influences on bladder compliance during filling. Compared with these of the state of rectal empty, the thresholds of first filling sensation, first desire to void and strong desire to void were significantly decreased when the rectum was full. Conclusions：There may exist a nervous reflex pathway between the rectum and bladder that can influence the bladder filling sensations. Before cystometric tests, we should examine the state of rectum in case the state of rectal fullness might influence the bladder filling sensa tions evaluating.
