Useful For/Utility
Diagnosis of urinary tract infections. Quantitative culture results may be helpful in discriminating contamination, colonization, and infection. Identification and susceptibilities will be performed on all microbiology isolates considered by the laboratory to be significant.
Methodology
Direct smear not performed.
Clinical Information
Urinary tract infection (UTI) encompasses a broad range of clinical entities that vary in their clinical presentation, degree of tissue invasion, epidemiologic setting, and antibiotic therapy requirements. There are 4 major types of UTIs: urethritis, cystitis, acute urethral syndrome, and pyelonephritis. UTIs may also be classified as uncomplicated or complicated. Escherichia coli the leading cause of uncomplicated community-acquired UTI. Risk factors that predispose one to complicated UTIs include: underlying diseases that are associated with kidney infection (e.g., diabetes), kidney stones, structural or functional urinary tract abnormalities, and indwelling urinary catheters. Another classification of UTIs is upper UTI (related to the kidney, renal pelvis or ureter) or lower UTI (urinary bladder and urethra). The classic symptoms of upper UTI are fever (often with chills) and flank pain; frequent painful urination, urgency and dysuria are more often associated with lower UTI.

Whenever possible, culture specimens should be obtained before antibiotics or antimicrobial agents have been administered.

Cautions
Although urine is normally sterile, contamination by organisms normally present in the urethra or on periurethral surfaces can allow a proliferation of these organisms yielding misleading urine culture results. Urine obtained from catheter bags at the beside and Foley catheter tips are unacceptable for culture.
