 Small stones in female dogs may possibly be removed by urohydropropulsion, a nonsurgical procedure.Urohydropropulsion is performed under sedation by filling the bladder with saline through a catheter, holding the dog vertically, and squeezing the bladder to expel the stones through the urethra.Bladder stones can be removed surgically by a cystotomy, which is a small incision into the bladder to scoop out the stones.
