BERLIN -- A Berlin zoo says a giant panda whose twin cubs have captured international attention has undergone a CT scan after veterinarians discovered one of his kidneys was smaller than the other.
The zoo said Tuesday that 9-year-old Jiao Qing was examined last week by experts at the city's Leibniz Institute for Zoo and Wildlife Research after the discrepancy was picked up on an ultrasound.
The 110-kilogram (243-pound) bear underwent the scan while under anesthesia. Doctors confirmed one kidney is smaller.
Jiao Qing is the father of twin cubs born Aug. 31. They are doing well.
