Symptoms and when it is urgent
Burning, frequency, urgency, lower abdominal discomfort and cloudy or foul-smelling urine point to a lower tract infection. Fever with chills, flank pain, vomiting or confusion in an older adult suggests the kidney is involved and needs assessment the same day.
- Burning or pain while passing urine
- Going very frequently, often passing only a small amount
- Fever above 100°F with back or flank pain
- Blood in the urine
- Symptoms in pregnancy, in diabetes, or with a catheter — all need prompt treatment
Treat the bug, not the guess
A urine routine test and culture with sensitivity should guide the antibiotic wherever possible. Repeated courses of broad-spectrum antibiotics chosen blindly are the main driver of the resistant infections now seen routinely, and they also mask the underlying cause — a stone, an obstruction, or incomplete bladder emptying.
When a urologist should be involved
Any infection in a man, any infection with fever, infections that recur, infections with blood, and infections in someone with stones, diabetes, a catheter or prostate enlargement. In these cases an ultrasound to check for obstruction and residual urine is part of proper treatment, not an optional extra.
Urinary Tract Infection (UTI) Treatment — common questions
Can a UTI clear without antibiotics?
A very mild bladder infection sometimes settles with hydration, but symptomatic infection usually needs a culture-guided antibiotic, and delaying treatment risks the kidney.
Why do I keep getting UTIs?
Common reasons include incomplete bladder emptying, stones, prostate enlargement, diabetes, menopause-related changes, and behavioural factors. Recurrence is a reason to investigate, not to repeat the same antibiotic.
Is cranberry juice useful?
Evidence is modest at best. Adequate fluids, complete bladder emptying and treating the underlying cause matter far more.
Do I need a scan for a single UTI?
Not usually in an otherwise healthy woman. In men, in children, and with fever or recurrence, imaging is appropriate.
