Abstract

OBJECTIVE

To compare the success rates for urethral catheterization in clinical patients using the traditional and 2-catheter techniques when placed by personnel of all experience levels.

ANIMALS

38 female cats and dogs weighing less than 10 kg were prospectively enrolled.

METHODS

Enrolled animals were randomized to have a urethral catheter placed by the traditional technique or the 2-catheter method under sedation or general anesthesia. Any qualified hospital personnel of any experience level were allowed to place the catheter. If after 5 minutes the animal was not successfully catheterized, the alternate method was performed. The previous experience of the catheter placer, animal signalment, animal condition that necessitated catheter placement, time to successful placement, and which technique was successful was recorded.

RESULTS

The 2-catheter technique was more successful than the traditional method (60.5% and 34.2%, respectively) for urethral catheterization when used by a variety of hospital personnel. The 2-catheter technique was successful in 63.3% of dogs and 66.6% of cats, while the traditional method was successful in 36.6% of dogs and 33.3% of cats. Eight of 9 (88.9%) novice catheter placers that placed their first urinary catheter in this study succeeded with the 2-catheter technique and only 1 was successful with the traditional method.

CLINICAL RELEVANCE

The 2-catheter technique has a higher rate of success for placement of female urinary catheters in small patients that are unable to have concurrent digital palpation. This technique may also be helpful in the inexperienced catheter placer population to aid in guidance into the urethral papilla.
