Removal of retained urinary catheters

Area of Science:

• Urology
• Medical Devices
• Minimally Invasive Procedures

Background:

• Urinary catheter retention poses a clinical challenge.
• Previous removal methods may leave debris or be time-consuming.

Purpose of the Study:

• To evaluate methods for removing retained urinary catheters.
• To introduce a novel ultrasound-guided removal technique.

Main Methods:

• In vitro testing of balloon deflation agents (ether, chloroform, liquid paraffin).
• Development and description of a diagnostic ultrasound-guided removal procedure.
• Analysis of 23 cases of retained urinary catheters over 1 year.

Main Results:

• Ether and chloroform rapidly disrupted catheter balloons in vitro.
• Liquid paraffin was slow and produced unacceptable debris.
• Diagnostic ultrasound effectively identified retained catheter balloons.

Conclusions:

• Chemical dissolution with ether or chloroform is effective for balloon deflation.
• Ultrasound guidance enhances the safe and efficient removal of retained urinary catheters.
• A multi-faceted approach is recommended for diverse retention scenarios.
