Bladder infusion versus standard catheter removal in urinary retention: a systematic review

Abstract

BACKGROUND

To compare the outcomes of bladder infusion and standard catheter removal in patients with urinary retention.

METHODS

We searched for the studies through Trip Database, MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus without any language restriction. We checked the references of included studies and manually searched for additional studies which were relevant. Criteria for inclusion in our meta-analysis included participants with urinary retention who were assigned randomly to remove the indwelling catheter by bladder infusion or standard catheter removal and the outcome was the time to discharge.

RESULTS

We identified four trials that met our inclusion criteria involving a total of 294 participants, who removed indwelling catheter by infusion bladder (132 patients) and standard catheter removal (162 patients). There was a statistically significant shorter time to discharge in the bladder infusion group than in the standard group (mean difference (MD) -5.6 hours; 95% confidence interval (CI), -9.06 to -2.21). In the inpatient's subgroup, there was no statistically significant difference in time to discharge between the bladder infusion group and the standard group (MD -9.06 hours; 95% CI, -19.36 to 1.23). In the dawn TOV subgroup, there was no statistically significant difference time to discharge between the bladder infusion group and the standard group (MD -6.41 hours; 95% CI -20.69 to 7.86). According to the time to decide to TOV, there was a statistically significant shorter time to decision to TOV in the bladder infusion group than the standard group (standard MD -0.69 hours; 95% CI, -1.02 to 0.37).

CONCLUSION

The bladder infusion method can reduce the time to discharge in the patients with urinary retention compared to the standard method.
