Non-deflating Foley catheter.
The different methods of removal of a non-deflating ureteral catheter were compared with the stylet technique. Two hundred and sixty randomly selected catheters were tested. Overdistention of the balloon with water or air and chemically induced rupture of the balloon produced fragments of various sizes in almost 100%. Our stylet technique failed to demonstrate any of the complications reported in the literature i.e., chemical or mechanical injury to the bladder or retained rubber fragments causing stone formation.
