Educational Gaps
Evaluating and treating bladder and bowel dysfunction are critical in reducing the risk of urinary tract infections (UTIs).
The pathogenesis of Escherichia coli infections reveals that quiescent intracellular reservoirs may be antibiotic-protected sources of recurrent infections.
Objectives
Review the documentation of UTI and the importance of the urine culture.
Understand the controversy over imaging and management of febrile UTIs in children.
Recognize the risk factors for recurrent UTIs and strategies for intervention.
Update information on the pathogenesis of E coli UTIs.
