When should a man be evaluated for underlying conditions after experiencing his first urinary tract infection (UTI)?

From the Guidelines

A man should be evaluated for underlying conditions after experiencing his first urinary tract infection (UTI) if he has certain concerning features, as UTIs are uncommon in men and may indicate potential complications. When considering the evaluation of a man with a first-time UTI, it is essential to take into account the potential for underlying conditions that may have contributed to the development of the infection. According to the European Association of Urology guidelines on urological infections 1, certain factors can increase the risk of complicated urinary tract infections, including obstruction at any site in the urinary tract, recent history of instrumentation, and underlying medical conditions such as diabetes mellitus or immunosuppression.

Key Considerations for Evaluation

• Fever over 101°F
• Flank pain
• Persistent symptoms after treatment
• Recurrent infections
• Abnormal urinary flow
• History of kidney stones
• Immunocompromised status
• Age over 50 years

These red flags suggest potential complications such as pyelonephritis, prostate involvement, anatomical abnormalities, or obstruction. The European Association of Urology guidelines recommend appropriate management of the urological abnormality or underlying complicating factor, as well as optimal antimicrobial therapy based on the severity of the illness and local resistance patterns 1.

Recommendations for Evaluation and Management

• Initial management typically involves antibiotics, with treatment duration ranging from 7 to 14 days depending on the severity of the infection and the presence of underlying conditions 1.
• Further evaluation, including imaging studies like ultrasound or CT scan, and possibly urologic consultation, may be warranted in cases with concerning features.
• The microbial spectrum of complicated UTIs is greater than that of uncomplicated UTIs, and antimicrobial resistance is more likely, highlighting the importance of appropriate antimicrobial therapy and susceptibility testing 1.

In summary, a man with a first-time UTI should be evaluated for underlying conditions if he has certain concerning features, and management should be tailored to the individual's specific needs and risk factors.

From the Research

Evaluation for Underlying Conditions

After experiencing a first urinary tract infection (UTI), a man should be evaluated for underlying conditions due to the following reasons:

• An underlying anatomic or functional condition usually complicates urinary tract infections in men 2
• Men presenting with symptoms indicative of UTI were predominantly elderly and 41% had additional risk factors 3
• Urinary tract infections in men are often associated with urinary tract procedures or anatomical or functional abnormalities 4

Timing of Evaluation

The timing of evaluation for underlying conditions is not explicitly stated in the provided studies. However, it can be inferred that evaluation should be done:

• Before treatment decision is made, as men with symptoms indicative of a UTI should not be treated empirically 3
• As part of the management of lower non-catheter-related urinary tract infection (UTI) in men, which includes antibiotic therapy and in most cases urological assessment 4

Factors to Consider

The following factors should be considered when evaluating a man for underlying conditions after a UTI:

• Age, as men presenting with symptoms indicative of UTI were predominantly elderly 3
• Presence of additional risk factors, as 41% of men with UTI had additional risk factors 3
• Type of UTI, as different types of UTI (urethritis, cystitis, and prostatitis) have different microbiology and management 4
