Long-term therapy for chronic bacteriuria in men. U.S. Public Health Service cooperative study

Area of Science:

• Urology
• Infectious Diseases
• Nephrology

Background:

• Bacteriuria in men can lead to recurrent infections and potential renal complications.
• Understanding prognostic factors is crucial for effective management of male bacteriuria.

Purpose of the Study:

• To evaluate the long-term response to therapy, renal function, and mortality in men with bacteriuria.
• To assess the impact of continuous antibiotic therapy versus placebo on bacteriuria recurrence and clinical outcomes.

Main Methods:

• A prospective study of 249 men with bacteriuria.
• Initial organism-specific antibiotic therapy followed by 2 years of continuous treatment with sulfamethizole, nitrofurantoin, methenamine mandelate, or placebo.

Main Results:

• Continuous therapy with active drugs delayed bacteriuria recurrence and reduced acute exacerbations.
• Factors like infection type, prostatic status, and presence of calculi influenced prognosis.
• Persistent bacteriuria did not lead to renal failure in the absence of severe urologic or renal disease.

Conclusions:

• Continuous antibiotic therapy is beneficial for selected male patients with bacteriuria.
• Prognosis is influenced by specific clinical and microbiological factors.
• Renal function is generally preserved in men with persistent bacteriuria without severe underlying conditions.
