World's heaviest kidney tumour weighing 5.5kg removed from woman’s stomach from Bihar

World's heaviest kidney tumour removed from a woman’s stomach weighing 5.5kg by Doctors from the civic-run Sion Hospital. The surgery was performed three months ago after which the tumour removed was termed as ‘heaviest’ which was later confirmed to be the heaviest tumour documented till date in the world.

According to the doctors, the surgery had several risks as the 5.5 kilograms (31 by 19 cm) tumour had completely covered her right kidney. A 28-year-old woman, Manjula Devi, resident of Darbhanga, Bihar had an abdominal lump on right side accompanied by pain and blood in urine for the last three years. “She travelled to Mumbai seeking treatment for her peculiar condition. She eventually approached the urology department of Sion Hospital,” said a doctor.

The size and weight of the tumour, which the doctors retrieved from the patient’s stomach, were of unimaginable proportions.

The doctor, who treated Devi, said that they conducted a CT scan in which it showed that there was a huge lump which completely replaced the kidney.

“The tumour which weighed 5.5 kg (31 by 19 cm) was taken out had completely replaced her right kidney. A huge tumour was compressing the liver and pushed the great vessels (inferior vena cava), intestines and the pancreas to the left half of the abdomen.,” said a senior doctor.

"She had persistent pain on the right side and was passing urine in blood. The tumor —31cm by 19cm—was compressing the liver and pushing the vessels, intestines and the pancreas to the left half of the abdomen. She was referred to multiple hospitals over the past three years but the surgery was deferred because of the size of the tumour," stated a release from Sion Hospital.

"The enormity of the surgery can be understood by comparing the weight of the kidney tumour—5.5kg—with that of a normal kidney, which is 110gm to 140gm," said Sawant. The patient was kept on ventilator for a day. She recovered completely in a week. Doctors said that Devi has returned to her normal life.

The official certificate from the world record managing team of the Guinness book has been recived by the hospital.

The head of the urology department of Sion hospital said that “The tumour was on her right side. Vital blood veins are on the right side of our body. If the tumour is massive then sometimes you have to open the chest. We had taken her family into confidence and had told them about the risks involved. I am really glad that we successfully carried out this surgery,” said Dr Ajit Sawant, Professor, and head of urology department.

Dr Sawant further added that after the surgery, Manju Devi has resumed her day to day activities and now is on regular follow-ups. She visits the hospital once in three months for a check-up.
