Unheralded urinary tract infection in the male. A clinical and urodynamic assessment

Fifty adult males presenting with unheralded single or recurrent urinary tract infections, but without prior urinary symptoms or disorders, were investigated by appropriate urodynamic techniques. Pressure/flow videocystography revealed significant underlying lower urinary tract abnormalities in 40 cases (80%) compared with only 11 (22%) whose abnormalities were also demonstrated by standard intravenous urography or endoscopy. We suggest that videocystography is the most efficient diagnostic procedure for these cases in a specialist unit but recommended the intravenous urodynamogram as a simpler screening test for general use.
