Ultrasound-guided injection of contrast medium into the crus penis for diagnosis of erection failure in bulls.

摘要: The objectives of this study were to demonstrate the ability cannulate crurae bull's penis under ultrasound guidance, contrast medium injected by route in distal penis, and confirm technique be safe repeatable. Five adult bulls with normal serving used, one being subjected procedure twice. was performed general anesthesia lateral recumbency. A spinal needle passed through skin into crus guidance two syringes containing an iodine-based connected it. Stimulation using electro-ejaculator a rectal probe initiated, when started developing erection, 50-100 ml injected. Lateral ventro-dorsal radiographs taken extended during, at intervals after, injection. After rest period 5 min, clearance confinned repeated on other penis. Each case therefore, contained attempts. Successful cannulation confirmed observing indentation its fibrous wall needle, free flow blood, lack resistance injection air, which could seen crus, fluctuation synchrony pulsation electroejaculator. Contrast demonstrated mid or portion all six cases, 9 12 Attainment penile larger volume medium, order enhanced first giving better results. On occasion worked out during stimulation, resulting corpus spongiosum All recovered uneventfully returned ability. It is concluded that ultrasound-guided successful method for studies less invasive than surgical method.
