Female with recurring UTI – USMLE exams
It is not uncommon for a female to experience recurring UTI’s, but we must differentiate between “relapsing” and “recurring” urinary tract infections.
RELAPSING UTI – If infecting organism is the same infecting organism within 2 weeks, it is a relapse.
RECURRENT UTI – If infection occurs after 2 weeks with the same organism, it is recurrent.
Thus, it is important to get a urinalysis and urine culture to determine the cause.
WHEN TO GIVE PROPHYLACTIC ANTIBIOTICS?
- When the patient experiences at least 2 infections in a 6 month period
- If the patient can link their UTI to sex, a single dose of antibiotics after coitus may be effective
- Before giving prophylactic antibiotics, it is essential to ensure the antibiotics get rid of the bacteria after a subsequent UTI
80% of UTI are caused by E.Coli, while the remaining are due to Klebsiella, Enterobacter, Staphylococcus, and group D strep.
