Patient's Query

Hi doctor,

My son has been suffering from pain while urinating. He is a 6-month-old baby boy. Here a local doctor did a urine test and said as an Escherichia coli urinary tract infection. What is the proper treatment for this?

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern.

As per the report, your child is having a urinary tract infection, which is resistant to many oral antibiotics.

The only oral antibiotic it is sensitive to is Cotrimoxazole. You can start a course of Septran for at least seven days and repeat a urine test after seven days. The other option is to start IV therapy with an injection of Ceftriaxone and Amikacin and repeat the test after five days. IV therapy is more effective than oral therapy. It is uncommon in a boy of this age to have a UTI, so we need to evaluate for the cause of UTI, as it might be due to some underlying conditions, which can be treated if diagnosed.

To evaluate for this, you need to do an ultrasound of the abdomen with the kidneys. Depending on the report, your pediatrician will guide you with further steps. Presently start with antibiotic therapy, either oral or IV, depending on your child's comfort level. Consult your doctor, discuss with him or her, and take the medicine with consent. There is nothing to panic about, as this is most commonly seen in children. It is not a serious condition and it is curable. So, relax and start the treatment.

I hope that you get your answer.

Please let me know if you need any help.

Thank you.
