Effects Of Intermittent Clamping On Bladder And Urethra Function In Patients With Short-term Indwelling Urethral Catheters:a Meta-analysis

Objective: Analysis the necessity of intermittent clamping in patients with short-term indwelling urethral catheter to provide scientific evidence for clinical nursing practice.Methods: A systematic literature searching method for studies which were published on PubMed,CNKI,CBM was performed in last ten years.We included randomized controlled trials related to intermittent clamping and free drainage in patients with short-term indwelling urethral catheters.We assessed the methodology quality of included researches and extracted data.RevMan 5.3 was used for meta-analysis.Results: Total of 12 studies were included.Meta-analysis showed that there was no statistical difference between the two groups in urination success RR=1.00,95%CI(0.97,1.03),P=0.79,abnormal residual urine volume RR=0.96,95%CI(0.55,1.67),P=0.89,urinary retention RR=1.02,95%CI(0.87,1.21),P=0.78,reinsertion of indwelling urethral catheter RR=1.02,95%CI(0.86,1.22),P=0.80,and urinary infection RR=1.08,95%CI(0.75,1.57),P=0.67.Conclusion: We suggest that intermittent clamping is not necessary to patients with short-term indwelling urethral catheters.
