Doctors at the All India Institute of Medical Sciences (AIIMS) have removed a kidney tumour weighing 5.018kg from a patient. The right kidney had bloated to 35 times the normal size, making it the world’s biggest ever kidney tumour so far on record. The patient, a resident of Bihar’s Darbhanga district, was facing acute pain in the right side of his abdomen along with lesions in his lungs. He was admitted to AIIMS with progressive huge mass abdomen. “The mass had been rapidly growing for the last two and three months. By that time, the cancer also spread to his lungs. "The surgery was the only option left before the cancer cells spread to other parts of the body. Earlier, the doctors at Sir Gangaram Hospital had removed a 2.5kg tumour,” Dr. M.D Ray, consultant, department of surgical oncology, AIIMS told Mail Today. Doctors had planned for radical nephrectomy with a resection of the lung lesion through a thoraco abdominal incision. Radical nephrectomy involves removal of entire kidney, along with a section of the tube leading to the bladder (ureter), the gland that sits atop the kidney (adrenal gland), and the fatty tissue surrounding the kidney. The patient was operated upon on May 14 through a 25cm incision from chest to abdomen. The procedure is called a thoracoabdominal incision. The tumour was compressed to the inferior vena cava (IVC), which is the main vein of the body. The surrounding structure was stuck to the mass so that it could be separated. "Another important gland, which is adrenal gland, was spared,” Dr Ray said. The mass was removed along with a part of the lungs to which the cancer had spread. Chest and abdomen were closed separately and respiratory muscles were repaired. “It was five-and-half-hour-long procedure. After the operation, the patient was in the ICU for a day, after which he was shifted to a general ward. He is doing well. He will be discharged on Thursday,” said Dr Ray. Source
