Morbidity and significant bacteriuria after urodynamic studies

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.
