A kidney weighing 2.75 kg, claimed to be the world's largest, has been removed from a 45-year-old patient, the authorities at a hospital here where the operation was performed said on Tuesday.Subash Yadav was suffering from autosomal dominant polycystic kidney disease (ADPKD) for a couple of years and was admitted to the Sir Ganga Ram hospital(SRGH) last month following chronic renal failure with severe pain in abdomen and blood in urine.
According to hospital authorities, the case was analysed closely and a decision was taken to remove both of his kidneys and transplant new ones. Also the other reason was the deteriorating condition despite being admitted to the hospital.The doctors remove the 2.75 kg kidney after a three-hour-long surgery.."We found the procedure quite challenging. Normal kidneys weigh 130 grams approximately. This kidney weighed 2.75 kg which is 20 times more and was stuck to the surrounding intestines," said Manu Gupta, consultant urological surgeon at SGRH and who performed the surgery.
"Even the second kidney of the patient also weighed 2.5 kg and had to be removed in an another surgery a week later," Gupta said and added that altogether, the patient's body was bearing an extra weight of about 5 kg.Gupta said that the dimensions of this huge kidney were 33 X 20 X 20 cm. This happens to be the largest kidney removed to date in the world.The Guinness Book of World Records reports a kidney weighing 2.15 kg as world's largest kidney till now which was removed in Dhule, Maharashtra in 2011. The dimensions of that kidney were 33.72 X 14.14 X 15.05 cm.Vinant Bhargav, consultant nephrologist at the hospital said that pre-transplant nephrectomies (removal of kidneys) is occasionally necessary in such situations.
"The patient is recovering well now and awaiting kidney transplant," he told IANS.
Talking about the disorder, medical experts said that Autosomal dominant polycystic kidney disease (ADPKD) is a dominantly inherited genetic systemic disease occurring in 1 in 1,000 individuals. The development of multiple kidney cysts results in slowly progressive enlargement of the kidney that leads to chronic kidney disease (CKD) in 50 percent of patients by the sixth decade.Symptoms of this disease include -- haematuria, a urinary tract infection (UTI), abdominal pain, an abdominal mass, kidney failure and hypertension.
