SURGICAL INSTRUMENTS 12 Catheters & Drains






Catheters & Drains
The Foley catheter is a plastic two-lumen tube with an 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 two wings at the tip. The de Pezzer catheter is based on a similar principle except that instead of wings, it has a bulbous end which can be straightened and recoils back when the wire introducer is removed.
         The catheters used are:
         •       Foley (Fig. 8.85)
         •       Gibbons (Fig. 8.86)
         •       Malecot (Fig. 8.87)
         •       DePezzer (Fig. 8.87)
         •       Tiemann (Fig. 8.87)
         •       Secured tube drains (Fig. 8.88)
         •       Corrugated (Fig. 8.89).
