In this prospective study we determined the cutoff value for post-void residual volume that places adult men at risk for bacteriuria.ĭata were obtained from 196 consecutive healthy adult men (median age 62 years) who came for prostate evaluation without symptoms of acute urinary tract infection. However, the maximum post-void residual volume that predisposes patients to a higher risk of urinary tract infection is not known.

Large post-void residual urinary volume may be related to the development of urinary tract infection.
