CATHETERS
The Foley catheter is a plastic two-lumen tube with an integral inflatable balloon. The balloon is inflated via a small channel.
Suprapubic cystostomy is an alternative way of draining the urinary bladder. The Malecot catheter is well suited for this purpose. It is a rubber or latex tube with wings at the tip. The de Pezzer catheter is based on a similar principal except that instead of wings, it has a bulbous end that can be straightened and recoiled back when the wire introducer is removed.
The catheters used are as follows:
· Foley
· Gibbon
· Malecot
· De Pezzer
· Tiemann
