Today’s case is a 9-year-old male neutered Border Collie with 8 days of difficulty urinating.
What was your technique here? What volume (approximate) of contrast agent was used and at what concentration? It looks like the tip of the red rubber catheter is only at the distal tip of the urethra, did you place it there, occlude the urethral orifice and retropulse from there?
We usually use a small balloon tipped catheter in the distal urethra to prevent leakage. You need to use iodinated contrast medium (ionic or non-ionic) and can dilute it to 50% strength. Start with 20-40 ml drawn up as you may want to do several radiographs while injecting. Take your radiographs during injection, using appropriate protective clothing and radiation safety practices. You should only need a few ml to distend the urethra. Sometimes you get a diagnostic and therapeutic study!
