Percutaneous antegrade urethral catherization
This can be a life saving approach to urethral obstruction. Urethral tears can occurs during attempts to catheterize an obstructed urethra. This may make it even more difficult to de-obstruct the patient. In this approach, a guidewire is passed from the bladder through the urethra via fluoroscopy guidance. Then, allowing a urethral catheter to be feed through the guidewire.
The video below reveals the passage of a guide wire through the urethra of a male cat with urethral obstruction and secondary urethral tear due to multiple attempts of catheterizing the urethra.
