Abstract

Objective: The primary aim was to determine Foley catheter balloon burst volumes and the effect of latex Foley catheter size on balloon burst volume. The secondary aim was to measure the effect of Foley catheter material on free fragment formation rate. This study also focused on special considerations for those with neurogenic bladder and spinal cord injury at or above T6.

Methods: This study analyzed 83 various sized silicone (n = 14) and latex (n = 69) Foley catheters. All catheters had 5 mL balloons. Each catheter was overinflated in vitro with water until the balloon ruptured, with volume (mL) and fragment formation recorded upon rupture. The effect of catheter size on the number of free fragments and burst volume was measured with linear regression. The likelihood of free fragment formation was compared between silicone and latex catheters with significance measured using Fisher's Exact Test.

Results: Free fragment formation occurred in 90% (62/69) of the latex catheters compared to 0% (0/14) of the silicone catheters. A higher proportion of free fragment formation occurred in latex catheters when compared to silicone catheters (P < 0.001). There was a positive effect of catheter size on burst volume (P < 0.001).

Conclusion: Balloon rupture by overdistention is an effective way to remove a retained catheter due to a non-deflating balloon. Post-bursting free fragment formation is common in latex balloons. This highlights the need for cystoscopy. Additionally, due to large fluid volumes needed to burst the balloon, this method should be discouraged in those at risk for autonomic dysreflexia.
