Intermittent urethral catheterization in elderly men commonly leads to urinary tract colonization but rarely causes infection. This method is safe for short-term bladder drainage when sterile techniques are used.

Area of Science:

  • Geriatrics
  • Urology
  • Infectious Diseases

Background:

  • Elderly patients often require bladder drainage.
  • Intermittent urethral catheterization is a common method used in hospital and nursing home settings.
  • The risk of urinary tract colonization and infection associated with this procedure in the elderly is a significant concern.

Purpose of the Study:

  • To prospectively evaluate the incidence of bacteriuria and urinary tract infection (UTI) in elderly male patients undergoing intermittent urethral catheterization.
  • To determine the time to colonization and identify common microorganisms involved.
  • To assess the safety and efficacy of intermittent catheterization in this patient population.

Main Methods:

  • A prospective study involving 35 elderly male patients receiving intermittent urethral catheterization.

  • Monitoring for the development of bacteriuria and symptomatic urinary tract infections.
  • Identification of causative microorganisms and time to colonization.

    • Main Results:

    • Urinary tract colonization occurred in 88.6% of patients, with a mean time to colonization of 5.7 days.
    • Persistent bacteriuria was observed in 17 patients, with common organisms including coagulase-negative staphylococci, Klebsiella pneumoniae, and enterococcus.
    • Symptomatic urinary tract infection developed in only 11% of patients, with infection being uncommon despite high colonization rates.

    Conclusions:

    • Intermittent urethral catheterization frequently leads to urinary tract colonization in elderly men, particularly those with poor functional status.
    • Symptomatic urinary tract infection is uncommon with this method.
    • Intermittent urethral catheterization is a safe and effective bladder drainage technique for elderly males when performed using sterile techniques for short durations.
