Formatted abstract
The role of subclinical infection in patients with urge incontinence has been largely ignored. The aim of this study was to test for the presence of intracellular bacteria in the urine of patients with detrusor overactivity or mixed incontinence +/- a history of UTI, and compare this to a control group of patients with stress incontinence and no history of infection. Bacterial cystitis was assessed by routine microbiology and compared to microscopic analysis of urine by Wright staining. Subsequent analysis of urothelial cells by confocal microscopy was performed to determine the existence of intracellular bacteria. Bacterial cystitis was seen in 13% of patients based on routine microbiology. Wright staining of concentrated urothelial cells demonstrated the presence of bacteria in 72% of samples. Filamentous bacterial cells were observed in 51% of patients and were significantly more common in patients with detrusor overactivity. Intracellular E. coli were observed by confocal microscopy. This study supports the possibility that a subset of patients with urge incontinence may have unrecognised chronic bacterial colonisation, maintained via an intracellular reservoir. In patients with negative routine microbiology, application of the techniques used in this study revealed evidence of infection, providing further insights into the aetiology of urge incontinence.
