Hello and welcome,
At your mothers age, UTI's are common, but not to worry.
You said your mother was diagnosed with a UTI, meaning her urine analysis had bacteria or pus cells in it? And if it was followed up, a urine culture should have also been done.
Let me explain these two tests to you. A urine analysis is a basic test which only helps us with superficial results like: glucose
would be present in a diabetic, ketones in one who has diabetic ketoacidosis
, pus cells in one who has an infection, and so on.
Now, once we are sure a urinary tract infection
(UTI) is present most doctors usually start patients on a course of the best suited antibiotic along with symptomatic treatment, like potassium replenishment, pain management and so on.
But, we do conduct a urine culture test at the same time, this takes at least 48 hours to give us a report. This test is a significant one. It helps a doctor determine which antibiotic would best kill the organism that is causing the infection, and in turn even prevent frequent recurrences.
Now that we have gone through that, I do not understand the fact that you have stated a 'negative' result of the same test. A negative result would mean absent bacteria, which means the infection is not present anymore.
If the bacteria is still present we will have to work in accordance to the urine culture report and see which antibiotic would be most effective in killing the causative organism. I advice a urine culture, and a proper course of the most sensitive antibiotic.
I would also advice an ultrasound
of the abdomen and pelvis to rule out the worst, which is also good for your mother, as regular check-ups after the age of 40, for women are essential.
Hope your mother recovers soon.
