Strawberry, a three-year-old female guinea pig, was seen by Dr. Olivia Petritz, our board-certified exotics specialist. Strawberry presented for an evaluation of a bladder stone, which had been diagnosed by her primary veterinarian. After consulting with Dr. Branter, the head of Interventional Radiology/Endoscopy and Urology, Strawberry’s family decided to try to remove the stone without surgery.
Using a small, rigid cystoscope and basket specialized for stone removal, Dr. Branter was able to retrieve the stone and avoid an invasive surgical procedure. The stone was analyzed and the results showed that it was composed of calcium carbonate, which is the most common type of stone in guinea pigs.
Strawberry recovered much more quickly than if she had undergone surgery. She was sent home soon after the scope with antibiotics and pain medication to recover with her family. She will have periodic x-rays to check for the formation of new stones, which will allow us to find any future stones early enough to remove them with an even less invasive method called voiding urethral hydropulsion, or flushing out of stones.
