Two cases are described, one of Haemophilus influenzae urinary infection in a female with no past history of urinary tract infection (UTI) and the other of Haemophilus parainfluenzae infection in a male with a renal calculus. Haemophilus spp. are rare urinary pathogens and these cases are even more unusual because H. influenzae UTI has almost always previously been found in either children or adult males, while H. parainfluenzae UTI has only been reported once before.
