Abstract：Objective:To explore the influence of increasing the insertion length of double balloon catheter on the efficacy of urethral catheterization in male patients. Methods:78 male patients who received urethral catheterization during operation under anesthesia were randomly divided into the observation group(n = 44)and the control group(n = 34). The common double balloon catheter was convention-ally fixed after it was catheterized in the control group;the insertion length of double balloon catheter was increased and fixed after it was catheterized in the observation group. The one - time success rate of catheterization,depth of catheterization,efficacy of urethral catheteriza-tion,systolic and diastolic blood pressure and heart rate when the patients were given urethral catheterization were compared between the two groups. Results:The one - time success rate of catheterization was 88. 2% in the control group and 100% in the observation group,the difference was statistically significant between the two groups(P < 0. 05);the depth of catheterization was 20. 61 ± 0. 41 cm in the control group and 30. 60 ± 0. 57 cm in the observation group(P < 0. 01);the efficacy of urethral catheterization was better in the observation group than the control group(P < 0. 01);the systolic and diastolic blood pressure and heart rate was significantly better in the observation group than the control group when the patients had the first urination(P < 0. 05). Conclusion:Increasing the insertion length of double balloon catheter can effectively improve the one - time success rate of catheterization and the efficacy of urethral catheterization and can also im-prove blood pressure and heart rate of the patients when they have the first urination.
