Giant vesical calculas and anuria.

A 50-year-old fisherman developed uremia and anuria, due to a giant vesical calculus. He was treated with suprapubic lithotomy, and a calculus weighing 1 640 g was removed. This may be the largest calculus ever removed with recovery of the patient. No other reports of giant stones leading to anuria has been found in the available literature. More than 4 years later an inoperable carcinoma of the bladder was discovered. The long delay in diagnosis of the giant stone, as later of the carcinoma, was due to the patient's lack of confidence in doctors and hospitals.
