Step by Step Procedure
1. Preferably the ferret should have an empty stomach prior to being anesthetized. Since the gastric emptying time of a ferret is 2 hours, the ferret should have food withheld at least that long.
2. Anesthetize the ferret with isoflurane gas anesthesia.
3. After pre-measuring the catheter, have an assistant expose the penis while you aseptically prepare the penis and adjacent preputial tissue with chlorhexadine surgical scrub and rinse with sterile saline. Repeat scrub and rinse 3 times.
4. While wearing sterile gloves, gently roll the shaft of a sterile 25 gauge needle on the ventral surface of the penis where the pink penile tissue and white os penis meet to identify the urethral orifice.
5. Once the urethral orifice has been visualized , utilize the tip of the sterile 25 gauge needle, bevel down to prevent inadvertently cutting the urethral tissue, to lift it open. Then thread the 3-1/2 French red rubber catheter into the opened urethral orifice. Difficulty will be experienced curving around the pubis. Placement of the catheter can be checked with radiographs.
6. Once in place, the exposed part of the catheter is curved dorsally to rest along the dorsum and the dorsal surface of the base of the tail. The catheter is sutured to the skin near the prepuce, and taped to the body. Tape is often placed completely around the body of the ferret and around the base of the tail.
7. A syringe or bag is then placed on the exposed end of the catheter, taking care to cover all exposed rubber parts with self-adhesive wrap.
8. Correct underlying disease cause.
