One day, Brigham Nordstrom of Hautapu, New Zealand got a kidney infection and was admitted to the hospital. There, doctors found out that he's got a little something extra:
"The doctors took a scan. Then I had to get a second one done. They wanted to have another look."
Doctors had found one duplex kidney and one triplex kidney. Instead of having one tube or ureter joining each kidney to the bladder, Mr Nordstrom had two tubes on the left and three on the right.
Accordingly, the duplex kidney has two parts and the triplex has three parts, meaning it is quite likely Mr Nordstrom has five kidneys altogether.
