Types of Coude Catheters

Urinary catheters are used to drain the bladder. They may be required when a patient suffers from urinary incontinence or retention; before, during or after surgical procedures or when a medical condition or trauma prevents satisfactory emptying of the bladder. A Coude catheter refers to any catheter that has been fitted with a Coude tip, which is an angled tip designed for easy insertion. The Coude-tipped catheter is available from a variety of manufacturers and in a number of sizes.

Manufacturers

• Coude catheters are made and marketed by a number of manufacturers. Brand names of Coude catheters include Astra Tech LoFric, Bard Catheters, Coloplast, Cure, Hollister, Mentor Self-Cath, Rochester and Rusch. Coude catheters are available in hydrophilic varieties, which have a layer of polymer coating bound to the surface that creates a slippery surface, allowing for easier insertion into the urethra.

Sizing

• Catheter sizing is indicated by a measurement known as French, or FR, where 1FR equals 0.3 millimeters. In general, catheters can range from 5FR to 26FR. Catheter sizes from 5FR to 16FR are considered pediatric catheters, though they also may be used for patients who are suffering from urethral stricture, an abnormal narrowing of the tube that carries urine out of the body from the bladder. Coude-tipped catheters are available in sizes 6FR to 24FR.

Benefits

• Coude catheter tips aid medical professionals and patients with safe and painless catheter insertion. The tip is designed to prevent stricture, scarring and other types of damage to the urethra. Coude-tipped catheters are always necessary for patients who cannot use a straight catheter because of a small or damaged urethra. In the case of patients who must continually self-catheterize because of a chronic medical condition or trauma to the urethra, the Coude-tipped catheter provides easier insertion and use.

Availability

• Patients may purchase Coude catheters without a prescription at a medical supply store, drugstore or through medical supply companies that offer online purchase. While no prescription is needed, the patient may want to obtain a letter of authorization from a physician to avoid any issue when purchasing the catheters.
