Use of a rigid endoscope to teach urethral catheterization of the female dog

Urethral catheterization of the female dog is known to be a challenging procedure. The authors describe a catheterization technique in which they use a rigid endoscope to visualize the canine urogenital vestibule during the procedure. The technique is particularly helpful as a training tool for students who are not yet experienced with the canine anatomy. The endoscope is attached to a video camera and monitor, allowing others to observe and learn the procedure.
