An 8 year old boy during a routine checkup is found to have E. coli 1,00,000 cc/ml on a urine culture. The urine specimen was obtained by mid–stream clean–catch void. The child is asymptomatic. Which is the most appropriate next step in the management –
(A) Treat as an acute episode of urinary tract infection (B) No therapy (C) Prophylactic antibiotics for 6 months (D) Administer long term urine alkalinizer
(A) If the urine culture shows 3100000 colony counts/ml, the definitive diagnosis of U.T.I. is confirmed.


It does not matter whether the patient is symptomatic or asymptomatic. If the diagnosis of U.T.I. is confirmed on urine culture, the patient should be treated accordingly.


Criteria for diagnosis of U.T.L on midstream urine sample -

ci If 3100,000 colonies/ml --> UT! confirmed (Does riot matter whether it is symptomatic or asymptomatic).

If 10000 colonies/ml and the patient is asymptomatic --> UTI unlikely
If 10000 colonies/m1 with sympt6ms of U.T.I. --> U.T.I is likely
