Comparison of Pre-procedural PCR and Culture-based UTI Assessment Prior to Intravesical Botox Injection

A Retrospective Comparison of Pre-procedural PCR and Culture-based UTI Assessment Prior to Intravesical Botox for the Treatment of Neurogenic or Non-neurogenic Overactive Bladder

This study is a retrospective record review to determine whether a novel multiplex PCR assay can be utilized as a screening method for UTI in patients receiving Botox injection to treat overactive bladder (OAB).

The novel multiplex real-time PCR assay with mixed floral antibiotic resistance profiling offers a higher degree of sensitivity and specificity than conventional culture methods in the identification of UTI pathogens as determined by a previous prospective comparison study. This is a retrospective record review comparing PCR and culture-based assessments for UTI in patients receiving Botox injection to treat overactive bladder (OAB). Investigators aim to determine whether M-PCR/P-AST can be utilized as a screening method for UTI in these patients and whether whether antibiotic prophylaxis, peri-procedural antibiotics, and post-injection antibiotic therapy based on patients' pre-procedural M-PCR/P-AST results in improved response to Botox injection compared to standard of care. The attributes and advantages of PCR testing over the use of traditional urine cultures, and the potential identification of polymicrobial infections with complicated resistance sharing mechanisms, may significantly improve patient care.

Inclusion/Exclusion Criteria:

• Subject is male or female
• >18 years of age at date of injection
• Subject receiving BoNT injection for symptoms of OAB (including urgency, urinary incontinence, and detrusor overactivity) refractory to first-line therapies
