At the Minnesota Urolith Center, we developed voiding urohydropropulsion (VU), a nonsurgical method of removing small bladder stones from dogs and cats.  Stone removal typically takes a few seconds and is successful, compassionate alternative to surgical stone removal.  Voiding urohydropropulsion requires lifting the anesthetized animal into a vertical position, and can be cumbersome in large dogs.  To assist with the procedure, we use a tilting exam table.  Video of voiding urohydropropulsion in a 6 year old, male-neutered dalmatian using a tilting exam table.
