Võ Thị S of HCM City had a staghorn stone measuring 74mm by 48mm in her left kidney, the largest the hospital has ever removed, Nguyễn Hoàng Đức, head of the urology department, said.

It was a complicated and rare case since the stone occupied the entire kidney, Đức said, explaining that untreated staghorn stones could destroy the kidney and cause a life-threatening infection.

Nearly 98 per cent of the stone was broken and removed through four procedures.

The most effective treatment for staghorn kidney stones is percutaneous nephrolithotomy surgery, but it can be performed at very few hospitals without a urology department, according to Đức.

Five years ago the woman was diagnosed with the staghorn stone but refused to undergo surgery to remove it for fear of pain and complications. Ten years ago she had had normal-sized stones that were removed surgically.

Doctors at the hospital perform thousands of percutaneous nephrolithotomy operations for kidney stones every year, though less than a dozen are for staghorn stones, Đức added.
