Urodynamic Risk Factors for Urinary Infection.

Area of Science:

• Urology
• Nephrology
• Infectious Diseases

Background:

• Urinary tract infections (UTIs) are commonly associated with lower urinary tract dysfunction (LUTD).
• Urodynamic investigation (UDI) is the gold standard for assessing LUTD, but its role in identifying UTI risk factors is not well-established.
• Existing studies suggest a link between storage and voiding dysfunctions and recurrent UTIs.

Purpose of the Study:

• To explore the value of UDI in identifying risk factors for UTIs.
• To investigate the association between specific UDI findings and UTI risk.
• To highlight the need for further research into UDI-guided therapies for UTI management.

Main Methods:

• Review of existing studies linking LUTD and UTIs.
• Analysis of specific UDI findings (e.g., low bladder capacity, high detrusor pressures, detrusor overactivity) and their association with UTI risk.
• Identification of limitations in current evidence, such as lack of control groups and therapeutic interventions.

Main Results:

• High rates of storage and voiding dysfunction observed in patients with recurrent UTIs.
• Specific UDI findings, including low bladder capacity, high detrusor pressures, and detrusor overactivity, are associated with increased UTI risk, particularly in kidney transplant recipients and infants.
• Current evidence is limited, hindering definitive conclusions regarding the causal relationship and therapeutic implications.

Conclusions:

• A potential causal link exists between LUTD and UTIs, supported by observed associations between UDI findings and UTI risk.
• Further well-designed studies are required to establish causality and evaluate the efficacy of UDI-guided therapies in improving UTI outcomes.
• UDI may play a role in identifying individuals at higher risk for UTIs, but its clinical utility requires further validation.
