目的:探讨自制尿道导向器在首次导尿失败中的应用和疗效。方法:将56例首次导尿失败的患者随机分成两组,一组28例,采用自制尿道导向器导尿(自制组),保持导向器头部轻贴尿道12点缓慢推进;一组28例,采用传统的补救方法,如导尿管内置金属导丝、尿道扩张、手法协助尿管等(对照组)。结果:自制组28例患者均一次操作成功,顺利置入导尿管,无明显尿道疼痛和血尿;对照组28例患者导尿成功20例,失败8例,其中伴有尿道疼痛11例,肉眼血尿8例。两组疗效比较,差异有统计学意义(P<0.05)。结论:自制尿道导向器在首次导尿失败中应用效果良好,操作快速简单,能确保导尿成功,有显著优势。
Objective: To investigate the application and efficacy of self-made urethral guide in the first failure of catheterization. Methods: Fifty-six patients with failed primary catheterization were randomly divided into two groups. One group consisted of 28 patients with urethral catheterization (self-made group) , Using the traditional remedies, such as catheter built-in metal guide wire, urethral dilatation, manual assistance catheter (control group). Results: 28 cases of self-made group were operated successfully, successfully placed in the catheter, no obvious urethral pain and hematuria; control group of 28 patients successfully catheterized in 20 cases, failure in 8 cases, including 11 cases of urethral pain, Hematuria in 8 cases. The curative effect between the two groups, the difference was statistically significant (P <0.05). Conclusion: The self-made urethral guide has good effect in the first failure of catheterization, the operation is quick and easy, and can ensure the success of catheterization, which has obvious advantages.
