Summary
Bacteraemia (bacteria in the blood) occurred in 7% of patients after urodynamic studies (UDS) without antibiotic prophylaxis. Pre-existing urinary tract infections increased this risk, highlighting infection as a key UDS morbidity factor.
Area of Science:
- Urology
- Infectious Diseases
- Medical Diagnostics
Background:
- Lower urinary tract symptoms (LUTS) affect a significant patient population.
- Urodynamic study (UDS) is a common diagnostic tool for LUTS.
- Infectious complications are a known morbidity factor associated with UDS.
Purpose of the Study:
- To determine the incidence of bacteraemia following UDS.
- To evaluate bacteraemia as a morbidity factor in UDS.
- To assess the impact of pre-existing urinary tract infections (UTI) on post-UDS bacteraemia.
Main Methods:
- Prospective study of 57 patients undergoing UDS for LUTS.
- Urine cultures obtained pre-UDS to detect UTI.
- Blood cultures collected pre- and post-UDS.
- No prophylactic antibiotics administered.
Main Results:
- No bacteraemia observed pre-UDS.
- Two patients (3.5%) had pre-existing bacteriuria.
- Four patients (7%) developed bacteraemia post-UDS.
- The two patients with pre-existing bacteriuria also had positive blood cultures post-UDS.
Conclusions:
- Bacteraemia can occur after UDS even with aseptic techniques.
- Pre-existing UTI is associated with an increased risk of post-UDS bacteraemia.
- Findings aid in patient counseling regarding UDS risks.
