Glossary Entry: Coude Catheter


Definition: A coude catheter is a type of urinary catheter with a curved or bent tip designed to navigate past obstructions in the urethra, making it suitable for patients with prostate enlargement or other anatomical challenges. It is commonly used in urological procedures and for managing urinary retention.

Detailed Description

Types and Variations

Variations: Coude catheters are available in different sizes and materials, such as silicone or latex, to accommodate varying patient needs. Some variations may also feature additional lubrication for smoother insertion.


Common Uses: Coude catheters are commonly used in patients with prostate enlargement, urethral strictures, or other obstructions that require a catheter with a curved tip to navigate past the blockage and facilitate urine drainage.

Insertion and Placement

Procedure: When inserting a coude catheter, it’s important to use a gentle, steady approach to navigate the curved tip through the urethra, following the natural contours to minimize discomfort and potential injury. Techniques like the Seldinger technique may be employed to facilitate insertion in certain cases.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with coude catheter use include urethral trauma, urinary tract infections, and discomfort during insertion due to the curved tip. Proper technique and patient education can help mitigate these risks.

Care and Maintenance

Maintenance Requirements: Regular hygiene and proper storage of coude catheters are essential to prevent contamination and ensure their effectiveness. Healthcare providers should educate patients on proper care and maintenance procedures.

Additional Information

Related Devices

Associated Terms: Other related devices used in conjunction with coude catheters may include urinary drainage bags, catheter securement devices, and lubricants for easier insertion.

Innovations and Advancements

Recent Developments: Recent advancements in coude catheter design have focused on improved materials, such as hydrophilic coatings for smoother insertion, and ergonomic features for enhanced patient comfort.

Regulatory and Safety Notes

Regulations: Coude catheters are regulated medical devices, and healthcare providers should adhere to relevant regulatory guidelines for their appropriate use and disposal.
