Chyluria as a cause of haematuria in patients from endemic areas.

Chyluria is an unusual cause of haematuria in temperate regions and is rarely considered even when no apparent cause has been found. We report 3 Guyanese men who presented with macroscopic haematuria in whom pyelo-lymphatic fistulae were found. In none of the patients were the symptoms severe enough for surgical disconnection of the fistula to be required.
