One of conjoined twin, who survived after an operation to separate her from her sister, died Friday morning in Wuhan, capital of central China's Hubei Province.

"She died of multi-organ prostration resulted from kidney failure this morning," said Tang Shaotao, a surgeon with Union Hospital in Wuhan who performed the operation.

Her sister died of respiratory failure two days ago, shortly after the twins were separated.

Doctors carried out an emergency operation Wednesday to separate the sisters at chest and abdomen. The operation lasted nearly five and a half hours from 12:30 a.m. to 6:05 p.m.

The twins shared one liver and small intestine, but had separate hearts, lungs, stomachs and spleens, noted Tang.

Tang said both babies were in stable condition when the operation ended.

"But in just 20 minutes, the girl with the lung infection developed breathing problems and her blood pressure started to fluctuate," according to the hospital.

The baby girl died at 6:45 p.m., 40 minutes after the operation.

The twins were born on July 12 in the city of Tianmen and were sent to Union Hospital for a checkup.

China has reported 27 sets of conjoined twins born 1949; 15 pairs have undergone separation operations.

But such a separation operation with large connection area at chest and abdomen when the newborns are only nine days old is the first one ever performed in China, said the local medical sources.
