Can I take antibiotics I have at home?
Please don't. Leftover or over-the-counter antibiotics may be the wrong drug or the wrong dose, and they can make the infection resistant. A urine culture helps choose the right antibiotic.
Why is a urine culture needed?
It confirms the infection and shows which antibiotics the bacteria are sensitive to. This matters most for repeated or severe infections, where common antibiotics often don't work.
Why do I keep getting UTIs?
Common reasons include not emptying the bladder fully, stones, diabetes, changes after menopause, constipation and sexual activity. An evaluation looks for a cause that can be corrected.
Is a UTI sexually transmitted?
A UTI is not a sexually transmitted infection, but sexual activity can push bacteria towards the bladder. Passing urine soon after intercourse helps.
Does cranberry juice prevent UTIs?
Evidence is mixed. Cranberry products may help a little for some women, but they do not treat an infection and are not a substitute for proper evaluation.
Do men with a UTI need tests?
Yes. UTIs are less common in men, so an infection usually has a cause — such as an enlarged prostate, a stone or incomplete emptying — that should be checked.
Can a UTI damage the kidneys?
A simple bladder infection rarely does. A kidney infection, especially with a blockage such as a stone, can be serious and needs prompt treatment.
What is emphysematous pyelonephritis?
A rare, severe kidney infection in which germs produce gas inside the kidney. It occurs mostly in people with diabetes, especially with poor sugar control, or when the kidney is blocked. Symptoms are high fever, side pain, vomiting and feeling very unwell. It is diagnosed with a CT scan and treated urgently in hospital with IV antibiotics, sugar control and drainage of the kidney (DJ stent or PCN tube); occasionally the kidney has to be removed.
How do I give a proper urine sample?
Wash your hands, clean the genital area with plain water, pass the first part of the urine into the toilet, and collect the middle part in a sterile container without touching the inside. Give it to the lab within 1–2 hours, or keep it in the fridge if there is a delay.
Is a UTI in pregnancy dangerous?
It needs prompt treatment because it can spread to the kidneys more easily in pregnancy. Urine is checked in early pregnancy and germs are treated even without symptoms, using only pregnancy-safe antibiotics.
My urine culture shows germs but I have no symptoms. Do I need antibiotics?
Usually not. This is common in elderly people, diabetics and people with a catheter, and treating it does not help. It is treated mainly in pregnancy and before urological procedures.
Does cranberry juice cure a UTI?
No. It does not treat an infection. It may slightly reduce repeat infections in some women, but it is not a substitute for proper treatment.
