OMG!!!! Think about that if she was human sized, 10 times the size it is! It would be like having a large bowling ball in your bladder! Now consider trying to PASS that stone....I just passed out thinking about it.
I'm astonished this dog survived to get the surgery...and quite pleased as well.
I'm awestruck at this video, and also pleasantly surprised Youtube watchers paid for the entire surgery...good on ya, people.

So fascinating, especially the actual surgery.

Glad the pooch is all better.

with a stone that size you won't be thinking of passing - the urine would drain around it and if it obstructed then your kidneys would eventually fail.
You might be interested in stag horn calculi in humans - usually precipitated by proteus infection - these clog up the calyces in a branching fashion which would be impossible to pass.

The largest stone recorded in a human is believed to be this one at over 800grams.
