We studied the effectiveness of methenamine mandelate in preventing urinary tract infection in patients with neurogenic bladder dysfunction who were in a program of intermittent catheterization and bladder retraining. Nine of 17 patients (53%) became infected while receiving the drug, whereas 19 of 22 patients (86%) in a placebo group became infected during the trial. The difference in infection rates was statistically significant (P less than 0.02) and resulted primarily from the absence of gram-positive cocci and Pseudomonas species in the drug group.
