Chinese man complains of abdominal pain, finds out he has four kidneys

DOCTORS in the southern Guizhou province were in for a rare surprise when they examined a 28-year-old man who complained of abdominal pains – only to find he had double the number of kidneys an average person should.

Wang Kailian, from the Kaiyang county, was found to be among the one percent of the population in possession of four kidneys, a condition known as duplex kidneys.

According to a report by local newspaper, the Guizhou Metropolis Daily, Wang had to have one of his kidneys removed due to an infection.

The surgery was carried out successfully last week, and Wang is recuperating. Although some netizens have joked about Wang being able to gain rewards from his multiple organs, a report by the Guardian says fully-formed extra kidneys are actually “extremely rare”.

Duplex kidneys occur because of a glitch during the first trimester of a fetus’ life, as developing kidneys split into two. The most common cause of infection is when urine flows back up to the ureter.

The news report, translated by the South China Morning Post, speculates Wang’s anomaly may be genetic, as his older sister, father and grandmother have extra digits on their hands and feet.

His family was quoted saying he has always been energetic and healthy, and consumes more food than an average man.
