The stone, due to its irregular shape called as staghorn stone, filled her entire kidney. The stone was detected after she underwent an X-ray in Jun.
"Stones of such large sizes do not develop overnight; they take a few years to form. In her case, the stone was undetected because she was completely asymptomatic," said a senior consultant, Dr Anshuman Agarwal, department of urology, Fortis.
"I thought of undergoing preventive tests after I crossed 40. I was surprised to see such a big stone in the x-ray, as I had no sensation whatsoever," said Pushplata Guliani aged 41.
The doctors advised immediate surgery after the abnormally big stone was detected by employing percutaneous nephrostolithotomy (PCNL), a technique to remove large stones.
"Sixty per cent of the crushed stone was taken out in the first stage and the remaining removed in the final stage. We had to wait for the infection to settle down," added Dr Agarwal.
"Even a simple urine infection can be a reason for stones that can damage your kidney. Symptoms such as pain, blood in urine, heaviness at the back, burning sensation while passing urine should not be ignored," the doctor said.
