The Clinical Usage of the Air-Bulb Urinary Catheter for One Way Washing

Objective:To observe the clinical effects in preventing infection of urinary tract by using the air bulb urinary catheter retained for one way washing after colonrectal carcinoma surgery.Methods:All cases were divided into three groups at random.The air bulb urinary catheter for one way washing with 500ml Furacillin was used in 24 cases as experimental group.Ordinary air bulb urinary catheter with two cavities was used in 47 cases.24 cases without bladder washing were served as the first control group,and 23 cases with routine continuous bladder washing as the second control group.Urinary and catheter bacteria cultures before catheter withdraw and observation of urinary tract stimulation after catheter withdraw were performed in all the three groups.Results: There were statistical significant differences in the positive rates of bacteria cultures from urine before catheter withdraw and from catheter after withdraw,in the incidence of urinary tract stimulation between experimental and control groups.Conclusion: The air bulb urinary catheter for one way washing with low flowing can reduce the infective rate of retained urinary catheter in the patients undergone colonrectal carcinoma surgery.
