改良留置导尿法在预防尿道损伤中的应用

Application of modified indwelling catheterization method for the prevention of urethral injury

目的：探讨改良留置导尿法对预防尿道损伤的效果,为临床寻找更合理的尿道损伤预防方案提供依据。方法将136例需留置导尿的患者随机分为观察组和对照组,每组各68例,观察组采用改良留置导尿法,对照组采用常规留置导尿法。于插入导尿管时、留置尿管期间、拔出导尿管后,观察两组患者血性尿发生情况。结果观察组患者尿管插入时、留置尿管期间、拔出尿管后及血尿总发生率均低于对照组,两组比较差异有统计学意义（χ^2值分别为6.81,3.89,8.38,28.57；P〈0.05）。两组患者留置尿管期间漏尿发生率差异无统计学意义（P〉0.05）。结论改良留置导尿法可以降低尿道损伤的发生率,值得临床推广。

Objective To study the effect of modified indwelling catheterization method for the prevention of urethral injury. Methods A total of 136 cases of urethral catheterization were randomly divided into two groups. The observation group had 68 cases using the conventional catheterization method, and the control group had 68 cases using the modified indwelling catheterization method, respectively. The time of inserting catheter, indwelling catheter time, removal time of the catheter, and the incidence of blood urine were compared between two groups. Results The time of inserting catheter, indwelling catheter time, removal time of the catheter, and the incidence of blood urine were significantly of the observation group were significantly lower than those of the control group （χ^2 =6. 81,3. 89,8. 38,28. 57, respectively; P〈0. 05）. The incidence of leakage of urine had no significant difference （P〉0. 05）. Conclusions The modified indwelling catheterization method can reduce the occurrence of hematuria traumatic urethral and it is worthy of application in clinical environment.
