一种新的动态技术研究肛肠功能已经发展。这包括在使用半固体放射性不透明造影剂排尿时直肠的放射显像，同时测量直肠内压力和肛门外括约肌的电活动。该方法已用于研究16例严重难以排出形成便的患者。研究表明，与正常受试者相比，这些患者在排尿过程中耻骨直肠肌和浅肛括约肌的活动异常增加（n = 6）。不能排空与张力时不能扩大肛肠角有关。
A new dynamic technique for the investigation of anorectal function has been developed. This involves radiological visualization of the rectum during voiding of a semisolid radio‐opaque contrast medium, and simultaneous measurement of the intrarectal pressure and electrical activity of the external anal sphincter. The method has been used to study patients (n = 16) with profound difficulty passing formed stool. It has demonstrated an abnormal increase in the activity of the puborectalis and superficial anal sphincter muscles during voiding in these patients, compared with normal subjects (n = 6). The inability to void was associated with failure to widen the anorectal angle on straining.
