In a 3-hour surgery, doctors at a Hyderabad hospital removed 156 kidney stones from a 50-year-old patient. The doctors said that this was the highest number of stones removed from a patient in India.

The patient, a school teacher, reported sudden pain in his abdomen. Screening showed a large number of stones in the kidney. News agency PTI reported that the doctors found the kidney located near the abdomen, instead of its normal position in the urinary tract.

The patient is also a case of ectopic kidney as it was located near to his abdomen, instead of its normal position in the urinary tract. Though the presence of kidney in an abnormal location is not the cause of the problem, removing stones from the kidney located abnormally was surely a challenging task, it said.

Dr V Chandra Mohan, Urologist and Managing Director, Preeti Urology and Kidney Hospital said, “This patient might have been developing these stones for more than two years, but never experienced any symptoms in the past. However, sudden occurrence of pain forced him to undergo all necessary tests which revealed presence of a large cluster of renal stones in the kidney.”

The extraction procedure included laparoscopy and endoscopy lasting for three hours. The patient, hailing from Hubli, was admitted to the Preeti Urology and Kidney Hospital.
