Management of retained Foley catheters.

Failure to deflate Foley catheters is a rare problem in clinical practice. There are various methods to overcome this problem. This is an experimental study of the commonly used methods. The balloons should never be inflated until rupture to prevent leaving loose fragments. A ureteric catheter or its stylet can be used to deflate the balloon. The balloon can be ruptured with fine needle under ultrasound guidance but it should not have been inflated to more than 50% of its volume to prevent leaving loose fragments in the bladder.
