– 7 year old MN Golden Ret. presented last week for stranguria/dysuria
– UA and culture negative for infection; initial reponse to Metacam and Aventi Clav
– presented 5 days later unable to urinate and profound stranguria;drible of dark borwn urine
– UB (huge), kidneys, prostate and proximal urethra normal; rest of scan normal including medial iliac LN’s
– scan of the distal urethra/penis showed lytic-like lesions, mineralization and soft tissue proliferation of the luminal tissues; power Doppler was not useful in this region
– ultrasound guided traumatic/suction biopsy did not yield cells or tissue; very small catheter was needed to pass through the region
Unfortuinately, the owners opted for humane euthanasia. This looks like a neoplastic lesion to me – osterosarc of the os penis? TCC? other? mineralizing severe distal urethritis?

Nasty looking lesion that is
Nasty looking lesion that is most likley neoplasia. Only real way of getting a diagnosis is via scope, which would allow visualization of the lesion and getting a biopsy.
Could do an us guided
Could do an us guided traumatic catheterization too
Did this with no luck – no

You had negative pressure by
You had negative pressure by the tech when traumatizing right… 60 cc syringe??
sharp bevelled edge cut on the catheter?
should have gotten some chunks

60 cc syringe with lots of negtative pressure but used a red rubber catheter with extra slots cut at the end. I think using a rigid catheter may have been a better option with sharper edge for sure to be more traumatic
Yes you need to use a rigid
Yes you need to use a rigid polypropylene catheter and cut the edge just like a needle end and lube it heavily to pass into place. Red rubber ceath fenestrated wont get the pieces.
