A meta-analysis comparing suprapubic and transurethral catheterization for bladder drainage after abdominal surgery.

BACKGROUND

Although bladder drainage is widely used for general surgical patients undergoing laparotomy, there is little consensus on whether suprapubic or transurethral catheterization is better.

METHOD

A systematic database search was undertaken to find all studies of suprapubic catheterization. Randomized controlled trials were identified for inclusion. Endpoints for analysis were bacteriuria, patient satisfaction and recatheterization rates. A meta-analysis was performed using fixed-effect or random-effect models as appropriate, depending on heterogeneity.

RESULTS

After abdominal surgery, transurethral catheterization is associated with significant bacteriuria (relative risk (RR)=2.02, P<0.001, 95 percent confidence interval (c.i.) 1.34 to 3.04) and pain or discomfort (RR=2.94, P=0.004, 95 percent c.i. 1.41 to 6.14). Recatheterization rates using the transurethral method were not increased significantly (RR=1.97, P=0.213, 95 percent c.i. 0.68 to 5.74) with heterogeneity between studies.

CONCLUSION

The suprapubic route for bladder drainage in general surgery is more acceptable to patients and reduces microbiological morbidity.
