Summary

Routine screening for urinary tract infection (UTI) before urodynamic investigations is not recommended, as asymptomatic bacteriuria rarely affects outcomes. However, about 20% of patients may develop a UTI post-procedure.

Area of Science:

  • Urology
  • Gynecology
  • Medical Microbiology

Background:

  • Urinary tract infections (UTIs) are common, and asymptomatic bacteriuria can be present before medical procedures.
  • Urodynamic investigations, such as cystometry, are used to assess bladder function.
  • The relationship between asymptomatic bacteriuria and urodynamic findings requires clarification.

Purpose of the Study:

  • To determine the incidence of unsuspected UTI before cystometry.
  • To evaluate if asymptomatic bacteriuria impacts cystometry results.
  • To assess the incidence of iatrogenic UTIs after cystometry.

Main Methods:

  • A prospective study involving 117 women undergoing urodynamic investigations.
  • Urine samples were collected before and after cystometry.

  • Data on patient demographics and urodynamic diagnoses were recorded.

    • Main Results:

    • 10.3% of patients had asymptomatic bacteriuria before cystometry, significantly associated with age and sensory urgency.
    • Asymptomatic bacteriuria did not significantly affect detrusor instability or stress incontinence.
    • 19.6% of patients developed a UTI after the procedure, with no significant association with baseline factors.

    Conclusions:

    • Universal screening for bacteriuria before urodynamic investigation is not supported by these findings.
    • Asymptomatic bacteriuria only influenced urodynamic outcomes in patients with sensory urgency.
    • Screening and treatment for bacteriuria should be individualized, particularly for older women with irritative bladder symptoms. Patient counseling regarding post-procedure UTI risk is advised.
