After consulting with urologist Dr. Joseph Marquez from Seattle's The Polyclinic, the zoo's animal health experts decided to use a procedure that, though used often on humans, is uncommon on zoo animals.
The 15-year-old monkey, named Fiona, was treated with a high-tech procedure that blasts kidney stones to passable pieces by repeated exposure to sound waves. Using a lithotripsy machine, generously supplied by NextMed, to send the sound waves, the team was able to break down Fiona's kidney stones into hundreds of small pieces that could then pass through her urinary tract.
Fiona is recovering well now at the zoo's award-winning African Savanna exhibit. After just one day, she was feeling much better than she had in the weeks leading up to the procedure, according to her vets.
