X RAYS

A rare case of sterile struvite in a dog. Almost 99% are infection-induced struvites with microbial urease involved. Hence, the owners did not know about the bladder stones till X-rays for lameness. These stones can be dissolved by S/D diet and change to C/D diet later.

Sometimes, a rare case appears. Urine must be collected to test for crystals.
