间歇性导尿对腰椎管狭窄术后患者拔除尿管后尿潴留的有效性研究

目的探讨间歇性导尿对腰椎管狭窄术后患者拔除尿管后尿潴留的临床效果。方法将腰椎管狭窄术拔除尿管后出现尿潴留72例患者随机分为对照组和观察组各36例，对照组运用常规尿潴留的处理流程：采用诱导排尿术，无效患者予重新留置尿管；观察组在运用诱导排尿术无效后，加用间歇性导尿处理，以上措施无效患者，予重置尿管。分别统计两组患者拔除尿管后各组实施尿潴留处理流程后重置尿管例数、发生尿道损伤及尿路感染例数。结果两组患者重置尿管例数、尿路感染例数观察组优于对照组（X^2=17．72和8．10，P〈0．01）；两组患者尿道损伤例数比较无统计学意义（X^2=0．465，P〉0．05）。结论腰椎管狭窄术后拔除尿管后尿潴留患者应用间歇性导尿，有利于患者尽早恢复自主排尿，减少重置尿管的机率，降低尿路感染的发生率。

The effect of intermittent catheterization on urinary retention after removal of catheter for patients with lumbar spinal stenosis surgery

Objective To discuss the effect of intermittent catheterization on urinary retention after removal of catheter for patients with lumbar spinal stenosis surgery. Methods Seventy-two cases of lumbar spinal stenosis surgery, which suffered from urinary retention after removal of catheter, were randomly, divided into control group （n=36） and experimental group （n=36）. Conventional methods were applied in control group while in experimental group, after the failure of inducing uri- nation, intermittent catheterization was taken. Catheter would be re-indwelled once combine measures were in vain. Cases of re-catheterization, urinary lesion and urinary infection in two groups were counted respectively. Results There was no statistical significance in number of urinary lesion in two groups by Chi-square test（X^2=0.465, P 〉0.05）; while the numbers of re-catheterization and urinary infection cases were significant better in experimental group than in control group （X^2= 17.72 and 8.10 respectively, P 〈 0.01）. Conclusion For patients with lumbar spinal stenosis surgery, intermittent catheteri- zation after removal of catheter could favor autonomous urination as early as possible and reduce probability of replacement urinary catheter,that decrease infection of urinary tract.
