Morbidity and significant bacteriuria after urodynamic studies
Annals of the Academy of Medicine, Singapore
|December 21, 2004
Summary
Urodynamic pressure flow studies (PFS) rarely cause significant bacteriuria (SBU). Most SBUs after PFS are asymptomatic and resolve on their own, making antibiotic prophylaxis unnecessary.
Area of Science:
- Urology
- Infectious Disease
Background:
- Urodynamic pressure flow studies (PFS) are common for lower urinary tract (LUT) dysfunction.
- PFS carries a theoretical risk of infection and morbidity.
- This study investigates post-PFS morbidity and significant bacteriuria (SBU).
Purpose of the Study:
- To determine the incidence and natural history of SBU after PFS.
- To assess the morbidity associated with PFS.
Main Methods:
- 93 patients undergoing PFS were enrolled.
- Urine cultures were collected at PFS (D0), 3 days (D3), and 7 days (D7) post-PFS.
- A 7-day symptom log was maintained.
Main Results:
- 13.9% incidence of SBU, with 95.7% being asymptomatic.
- Post-PFS symptoms were mild, transient, and rarely linked to infection.
- No correlation found between patient factors and post-PFS morbidity or SBU.
Conclusions:
- Symptoms after PFS are generally mild and self-limiting.
- Significant bacteriuria post-PFS is predominantly asymptomatic and resolves spontaneously.
- Antibiotic prophylaxis is not indicated due to the low risk of symptomatic infection.
