Overactive bladder in women: does low-count bacteriuria matter? A review
1Pelvic Floor Unit, St. George Hospital, University of New South Wales, Sydney, Australia.
Defining significant bacteriuria is crucial for overactive bladder (OAB) diagnosis. Low-count bacteriuria may be more relevant in OAB than previously thought, challenging traditional definitions.
Area of Science:
- Urology
- Microbiology
- Women's Health
Background:
- The definition of significant bacteriuria (>10^5 CFU/ml) is outdated and insensitive for diagnosing urinary tract infections in women.
- Low-count bacteriuria (10^2-10^5 CFU/ml) is increasingly recognized as clinically significant in women with acute urinary symptoms.
- The role of low-count bacteriuria in overactive bladder (OAB) syndrome remains understudied.
Purpose of the Study:
- To review the historical context and current understanding of significant bacteriuria in women.
- To explore the relevance of low-count bacteriuria in the diagnosis and management of overactive bladder (OAB) syndrome.
- To highlight the need for updated diagnostic criteria for bacteriuria in women with lower urinary tract symptoms.
Main Methods:
- Literature review of historical definitions and contemporary studies on bacteriuria.
- Analysis of microbiological thresholds and their clinical implications.
- Synthesis of current concepts in urology and microbiology related to OAB and urinary tract infections.
Main Results:
- Traditional significant bacteriuria thresholds are inadequate for women with acute urinary symptoms.
- Low-count bacteriuria is more prevalent in women with severe OAB than traditional significant bacteriuria.
- Current clinical practice has been slow to adopt updated microbiological findings.
Conclusions:
- The definition of significant bacteriuria requires re-evaluation, particularly for women experiencing OAB symptoms.
- Low-count bacteriuria warrants further investigation for its role in OAB pathogenesis and treatment.
- Updated diagnostic guidelines are needed to improve the management of urinary tract issues in women.
