[quote user="Virginia Campbell"] I'm not going to win any "animal vegetable or mineral?" games.[/quote]How about plastic? I've posted this case before but it's worth resurrecting it in the light of this thread.

We sent away a urolith from a bitch for analysis and the report came back that it was indeed oxalate as suspected but the stone was formed around a plastic washer. How did a plastic washer get in a dog's bladder we asked, and when explained to the owner there was only on way he turned to her and said, 'ooh poppy, someone's being abusing you'!

So needless to say we requested the washer back from the lab and on examination it was immediately obvious that it was the little plastic doughnut that sits in the bottom of a plain blood tube. We had sent the urolith to the lab in one of these but clearly hadn't emptied the doughnut out first. How it wasn't blindingly obvious to a lab technician when he/she emptied the tube or dawned on them that this would never have been in the bladder in the first place case beggars believe.

Ah. I'm not going to win any "animal vegetable or mineral?" games. Hadn't considered the middle option when looking at urine! Thanks all. Dog doing well per O so going to just sit tight.

[quote user="Martin Atkinson"]certainly a contaminant IMO.[/quote]

Probably, I've received a "clean" sample in an unwashed [empty!] Hellman's mayonniase jar.....

The green 'blocky bits' look like chlorophyll bodies so they must be of plant/algal origin, almost certainly a contaminant IMO.

This is urine from a 12yo male cocker that presented on 22/12 as the owner had seen blood staining at the start of urination. There was no dysuria per O and the dog was not noted to be PUPD. Physical exam was unremarkable apart from a little smegma at the tip of the penis. The dog is quite fat. Prostate had dropped too far forwards for me to reach.

I gave it 10 days' worth of amox-clav and explained to the owner that I'd like to get a urine sample at the end of abs even if better as uncomplicated cystitis with no underlying cause is a bit unusual in male dogs and I wanted to check for crystals.

Sample left in today (after much running around after dog) looks grossly N.

SG refractometer 1.040 dipstick -ve for everything ecept trace protein. pH 6.0.

Unspun urine unremarkable. Not much sediment when spun; a few red cells. Photo is 40x mag spun Sedistained urine. What are these filaments? I saw a few more of them. They look too long and skinny to be casts, but made up of more "blocky" sections than I would expect E.coli to be. Although happy to be corrected.
