Removal of retained urinary catheters.
In a 1-year register, retained urinary catheters were encountered on 23 occasions. In vitro tests showed that 2 ml of ether or chloroform injected through the inflation channel of catheter balloons caused disruption within a few seconds but liquid paraffin took over 20 min, leaving an unacceptable amount of debris. A new method of removal using diagnostic ultrasound to identify the balloon of the retained catheter is described, together with suggestions for removal of retained catheters occurring under different circumstances.
