Management of bacterial infections of the bladder, kidney, or urethra with appropriate antibiotic therapy and supportive care, guided by culture results.
Indication
- Frequent urination, burning during urination, urgency (signs of cystitis)
- Flank pain, fever, chills, nausea (upper urinary tract infection / pyelonephritis)
- Bloody, cloudy, or foul-smelling urine
- Recurrent urinary tract infection (2 or more episodes per year)
- Asymptomatic bacteriuria detected during pregnancy
- Positive urine culture before a urinary tract procedure
- Unexplained fever or confusion in elderly patients
Preparation
- Before treatment, urinalysis is performed and a clean midstream urine sample is collected for urine culture
- In complicated cases, blood tests, kidney function tests, and imaging may be requested
- Previous antibiotic use and allergy history must be reported
- Pregnancy status is reviewed; medications safe during pregnancy are selected
How it's performed
- In uncomplicated (cystitis) cases, empirical antibiotic therapy is started without waiting for the culture result
- Treatment duration is 3-7 days in uncomplicated cases and extends to 7-14 days in complicated ones
- In cases with flank pain, fever, or general deterioration, intravenous antibiotics are administered
- Plenty of fluid intake and, when needed, urinary tract analgesics are given to reduce pain and burning
- The antibiotic is changed if needed according to the culture result
- In recurrent or complicated cases, the underlying cause (stone, stricture, catheter) is investigated
Post-procedure
- Response can be evaluated with a urine culture 7-14 days after treatment is completed
- In recurrent infections, prophylactic low-dose antibiotics or behavioral measures are planned
- Adequate fluid intake, not retaining urine, and hygiene recommendations are important during long-term follow-up
- Urinary tract imaging may be performed 4-6 weeks after upper urinary tract infection
- A new culture is obtained in case of recurrent symptoms
Risks
- Progression of untreated infection to the kidney (pyelonephritis) and rarely sepsis
- Allergic reaction to antibiotics or disruption of intestinal flora
- Development of resistant bacteria in recurrent infections
- Risk of preterm birth from an untreated infection during pregnancy
- Deterioration of kidney function in complicated cases
FAQ
How long is the antibiotic used?
In uncomplicated lower urinary tract infection, 3-7 days is sufficient. In upper urinary tract or complicated infections, the duration extends to 7-14 days.
Is drinking plenty of water enough on its own?
Adequate fluid intake is supportive, but when a bacterial infection is confirmed, appropriate antibiotic therapy is required.
Why do my infections keep recurring?
Anatomical abnormalities, stones, incomplete bladder emptying, hormonal changes, or hygiene habits may play a role. A detailed evaluation is recommended.
Can I stop the medication once symptoms resolve?
No. If the treatment course is not completed, the infection may recur and resistant bacteria may develop.
