Haemophilus influenzae has rarely been implicated as the causative agent of urinary tract infections in adults. The isolation of H influenzae from a urine sample was first reported in 1898 when Kretz1 recovered influenzae bacillus from the urine sample of a 36-year-old man with hematuria and polyuria. Since then, only 20 cases have been reported that implicate H influenzae as the cause of adult urinary tract infections.2- 6 We report an additional case of H influenzae pyelonephritis in a 90-year-old man and discuss the possible underestimation of the true incidence of H influenzae in urinary tract infections.
