Urinary Tract Infection After Urodynamic Study in Women

Abstract

Objective: To assess the prevalence of urinary tract infection after urodynamic study in healthy women and its natural history.
Method: 210 consecutive incontinence women were recruited. All women screened for urinary tract infection before urodynamic study by mid-stream urine culture at least 1 to 2 months before investigation. All women then received a standard urodynamic investigation.
Results: The incidence of bacteriuria before and after urodynamic studies were 3.8% and 3.6% respectively. Bacteriuria was transient in 3 of the 7 women but persisted in 3 women. Only 1 of 7 bacteriuria gave rise to symptoms. Irritative bladder symptoms occurred in 49.7% and 17% of women on the day of procedure and day 2 after procedure respectively.
Conclusion: Urodynamic investigations were associated with a high incidence of transient irritative symptoms but a low incidence of bacteriuria (3.6%). Bacteriuria was asymptomatic in most patients. Its natural history was transient but may be persistent. In this population, urodynamic studies are associated with a low level of morbidity.
