冰水試驗於評估慢性脊髓病變患者之逼尿肌收縮

Abstract

This study attempts to define the reliability of ice-water test (IWT) in detecting the detrusor reflex in patients with chronic spinal cord lesion (SCL) and further explore its clinical application. 220 patients with SCL over a period of four years were included in this study. 105 of the patients were rated as the acute group with the injury less than six months. 115 patients with lesions over six months were grouped as the chronic one. All the patients underwent gas cystometrogram (CMG) and IWT within 48 hours. CMG revealed the presence of detrusor reflex. Comparing the results of CMG and IWT allowed us to determine the sensitivity and specificity of IWT. In addition, the high predictive values of IWT in detecting the detrusor reflex both at acute and chronic groups were obtained with a sensitivity of 90.2% in the acute group and 87.8% in the chronic group. However, the specificity of IWT in the chronic group was only 31.7% while it was relatively high in the acute group with 70.3%. Among the chronic SCL patients with the false positive IWT, the high proportion (75%) was diagnosed as a low compliance bladder. Based on the results in this study, we conclude that the reliability of IWT in detecting the detrusor reflex in chronic SCL is still inclusive and requires further study. Low compliance of the bladder might contribute to its uncertainty.
