Male external catheters

Male external catheters (also called condom or sheath catheters) fit over the penis like a sheath and drain urine into a leg bag or night bag, without inserting anything into the bladder. MEC stocks self-adhesive silicone catheters from Hollister InView and Ultraflex, and the non-adhesive Conveen Optima, all latex-free.

Choosing an external catheter

  • Size: a correct fit is the key to avoiding leaks and skin problems. Measure the diameter of the penis with the manufacturer's measuring guide and choose the matching size — for example 25 mm (Ultraflex small), 29 mm (Hollister InView medium) or 30 mm (Conveen Optima).
  • Adhesive or non-adhesive: self-adhesive catheters have adhesive built into the sheath. Non-adhesive catheters such as Conveen Optima use a separate grip strip.
  • Material: clear silicone is latex-free, breathable and lets you check the skin without removing the catheter.
  • Length: shorter sheaths such as the InView (4 cm) suit a wider range of body types.

Connect the catheter to a leg bag during the day and a 2 litre night bag overnight. Keep the tubing free of kinks so urine doesn't pool in the sheath.

Important: check the skin at every change. Remove the catheter and contact your nurse or doctor if there is redness, swelling, broken skin or pain. A catheter that is too small can restrict blood flow — if you are unsure of the size, ask a continence nurse to help with fitting.

External catheter FAQs

How often should an external catheter be changed?

External catheters are single use and are usually changed every 24 hours, or as the manufacturer directs. Wash and dry the skin between applications.

Who can use an external catheter?

External catheters suit men with urinary incontinence who empty their bladder normally. They are not suitable for urinary retention — speak to a doctor or continence nurse about the right option.
