Napoleon died of kidney failure: Danish doctor

Arne Soerensen, a retired Danish doctor, flips through thousands of pages of notes scribbled over 50 years of research and issues his diagnosis: Napoleon died of a kidney disease.

Soerensen has dedicated his life to studying the French emperor's health to debunk the myth that he was poisoned by his enemies or suffered from stomach cancer.

In the latest twist in a long-running medical saga, Soerensen wrote in a new book "Napoleon's nyrer" (Napoleon's kidneys) published in May claiming that the deposed emperor died at 51 of kidney and urinary problems that afflicted him for many years.
