There is clinical evidence of a relationship between urethrovesical and anorectal dysfunction in spinal cord injured patients. This study was performed to assess how rectal distension could influence the results of urodynamic investigations. Ten patients with spinal cord injury were submitted to repeated urodynamic evaluations under different rectal conditions after performing complete anorectal testing. Distension of the rectal ampulla may interfere with vesicourethral function in spinal cord injured patients: in those with complete spinal cord lesions rectal distension causes a reduction in bladder compliance, earlier and higher amplitude of the first hyperreflexic contraction, and an increase in detrusor-external urethral sphincter dyssynergia. We suggest that urodynamic evaluation of spinal cord injured patients should not normally be performed if the patient has a full rectum.
有临床证据表明脊髓损伤患者存在尿道膀胱和肛门直肠功能障碍之间的关联。本研究旨在评估直肠扩张如何影响尿动力学检查结果。10例脊髓损伤患者在完成肛门直肠检查后，于不同直肠条件下接受重复尿动力学评估。直肠壶腹扩张可能会干扰脊髓损伤患者的膀胱尿道功能：在完全性脊髓损伤患者中，直肠扩张会导致膀胱顺应性降低、首次反射亢进收缩的出现时间更早且幅度更高，以及逼尿肌-尿道外括约肌协同失调增加。我们建议，如果患者直肠充盈，通常不应进行脊髓损伤患者的尿动力学评估。
