What is Urine Culture and why does it matter?
Urine Culture — the definitive UTI test
The urine routine test tells you there IS an infection. The urine culture (C&S — culture and sensitivity) tells you WHICH bacteria is causing it and WHICH antibiotic will kill it. This takes 48–72 hours. Urine culture matters because antibiotic resistance is rising rapidly in India — E. coli (the most common UTI bug) is now resistant to many older antibiotics. A culture result prevents treating with the wrong antibiotic and helps avoid recurrent UTIs.
Most common UTI-causing bacteria in India
- E. coli — 80% of uncomplicated UTIs
- Klebsiella pneumoniae — especially in hospital-acquired UTIs
- Staphylococcus saprophyticus — common in young sexually active women
- Enterococcus — common in elderly men with prostate issues
When is a UTI serious (pyelonephritis)?
See a doctor urgently if you have: Fever above 38.5°C, shaking chills, pain in the back/flank (kidney area), nausea/vomiting, or if you are pregnant, diabetic, elderly or immunocompromised. These suggest the infection may have reached the kidneys (pyelonephritis) — requiring IV antibiotics in hospital.
Questions to ask your doctor
- Should I wait for the culture result before starting antibiotics?
- Why do I keep getting recurrent UTIs?
- Do I need a kidney ultrasound to rule out stones?
- How much water should I drink daily to prevent recurrence?
