Different clamping choices for patients with indwelling urethral catheter: a Meta analysis

Abstract

Objective To evaluate the effect of three different choices of indwelling urethral catheter clamping. Indwelling urethral catheter clamping choices included according to patients′ complaints to clamp the catheter(Group A), released as schedule(Group B), and smooth passway of indwelling urinary catheter all the way(Group C). Methods We searched RCT about the effect of different choices of indwelling urethral catheter clamping from CNKI, VIP database, Wanfang database, PubMed on line. Literatures were searched from the database had been established till now. Two reviewers evaluate the literatures independently according to the RCT authentic assessment manual of Cochrane Collaboration. Other than different results, negotiation took as the measure to attach an agreement. No agreement reached, consult the opinion of the third person. RevMan5.2 was used to analyses the result of the study. Results Statistical difference between three clamping choice on the rate of successful in autonomous urination after catheter removed: both group A and group B preceded group C(Z=2.97, Z= 4.34, P < 0.05), mean well group A preceded group B(Z=5.30, P < 0.05). Statistical difference did not found on the rate of urinary tract irritation after catheter removed between three choices. Conclusion Clamping indwelling urethral catheter according to patients′ complaints seems useful in bladder reconditioning before indwelling urethral catheter removal.
