Management of Urinary Tract Infection (UTI)
1. Classification
| Type | Definition |
|---|---|
| Uncomplicated cystitis | Lower UTI in a non-pregnant, non-immunosuppressed, anatomically normal adult |
| Complicated UTI | Structural/functional abnormality, recent instrumentation, recent antimicrobials, immunosuppression, pregnancy, or hospital-acquired |
| Acute pyelonephritis | Upper UTI involving renal parenchyma |
| Asymptomatic bacteriuria (ASB) | Positive culture without symptoms |
| Recurrent UTI | >2 episodes in 6 months or >3 in 12 months |
| CAUTI | Catheter-associated UTI |
2. General Approach Before Treatment
- Urinalysis + urine culture: required for complicated UTIs, pyelonephritis, and all cases before initiating antibiotics when possible. Not mandatory for straightforward uncomplicated cystitis.
- Consider local resistance patterns: if community TMP-SMX resistance >20%, choose an alternative agent.
- Imaging: consider renal ultrasound or CT for pyelonephritis that does not resolve within 72 hours (to exclude obstruction, abscess, or stone).
3. Uncomplicated Cystitis (Adult Women)
| Drug | Dose | Duration |
|---|---|---|
| Nitrofurantoin monohydrate/macrocrystals | 100 mg twice daily | 5 days |
| TMP-SMX DS (trimethoprim-sulfamethoxazole) | 160/800 mg twice daily | 3 days |
| Fosfomycin | 3 g single dose | 1 day |
| Pivmecillinam (where available) | 400 mg twice daily | 5 days (lower efficacy) |
Important: Fluoroquinolones should be reserved for more serious infections and not used routinely for uncomplicated cystitis due to collateral damage and resistance concerns. - Tintinalli's Emergency Medicine
4. Complicated Cystitis / Pyelonephritis (Outpatient)
| Drug | Dose | Duration |
|---|---|---|
| Ciprofloxacin | 500 mg twice daily | 5-7 days |
| Levofloxacin | 750 mg once daily | 5-7 days |
| TMP-SMX DS (if susceptibility known) | 160/800 mg twice daily | 14 days |
| Amoxicillin-clavulanate | 875/125 mg twice daily | 7-14 days |
| Cefpodoxime | 400 mg twice daily | 7-14 days |
5. Acute Pyelonephritis - Inpatient (IV Therapy)
| Drug | Dose |
|---|---|
| Ciprofloxacin | 400 mg IV every 12 h |
| Ceftriaxone | 1-2 g IV once daily |
| Cefotaxime | 1-2 g IV every 8 h |
| Gentamicin ± ampicillin | 3 mg/kg/day ÷ q8h ± 2 g q6h |
| Piperacillin-tazobactam | 3.375 g IV every 6 h |
| Cefepime | 1-2 g IV every 8 h |
| Ertapenem | 1 g IV once daily |
| Meropenem / Imipenem | 1 g q8h / 500 mg q8h |
- Step down to oral therapy once clinical improvement is achieved, guided by culture sensitivities.
- Fevers may persist up to 72 hours despite adequate therapy - this is expected and should not prompt immediate change.
- If fevers persist beyond 72 hours, obtain CT imaging to rule out renal or perinephric abscess (requires percutaneous drainage + IV antibiotics).
- Total course: 7-14 days for most patients; up to 21 days if sepsis syndrome is present.
6. Asymptomatic Bacteriuria (ASB)
- Pregnant patients (risk of progression to pyelonephritis up to 40%, plus adverse fetal outcomes)
- Patients undergoing urologic instrumentation / surgery
7. UTI in Pregnancy
- Asymptomatic bacteriuria: always screen and treat (quantitative urine culture preferred; dipstick has high false-negative rate in pregnancy)
- Safe antibiotics: beta-lactams (amoxicillin-clavulanate, cephalosporins), nitrofurantoin, fosfomycin, metronidazole, clindamycin
- Avoid: fluoroquinolones and tetracyclines (contraindicated in pregnancy)
- Acute pyelonephritis in pregnancy (peaks at 20-28 weeks) may cause sepsis, endotoxic shock, DIC, acute renal failure, and respiratory failure; warrants hospitalization and IV therapy
- Nephrolithiasis complicated by UTI: antibiotics for 3-5 weeks, suppressive therapy after delivery - Brenner and Rector's The Kidney
8. Catheter-Associated UTI (CAUTI)
- Remove or replace the urinary catheter before collecting cultures and initiating antibiotics
- Bacteria form biofilms on catheter surfaces that protect them from antibiotics, making treatment less effective
- Treat symptomatic CAUTI; do not treat ASB in catheterized patients routinely
- Duration: 7 days (mild/moderate); longer courses may be needed for severe disease
- Prevention remains the cornerstone: minimize catheter use, use aseptic insertion technique, maintain closed drainage systems
9. Recurrent UTI
- Continuous low-dose antibiotics: nitrofurantoin, TMP-SMX, or cephalexin
- Postcoital prophylaxis: single-dose antibiotic after intercourse (for coitally-related recurrences)
- Self-initiated therapy: patient-initiated short course at symptom onset
- Vaginal oestrogen: 3-month course in postmenopausal women (reduces mucosal atrophy and restores protective vaginal flora) - Bailey & Love's Surgery
- Non-antibiotic prophylaxis: cranberry products (mixed evidence from meta-analyses), D-mannose, oral bacterial vaccines (OM-89/Urovaxom) - Campbell-Walsh-Wein Urology
The 2025 AUA/CUA/SUFU guideline update on recurrent uncomplicated UTI in women highlights non-antibiotic UTI prophylaxis and the genitourinary microbiome as key new areas of emphasis (J Urol. 2026;215:3-12).
10. Special Populations
Pediatric UTI
- Empiric oral therapy is acceptable for most febrile UTIs in children; parenteral therapy for severely ill neonates/young infants
- Cover for Enterococcus in neonates and young infants
- Common oral agents: cefixime, cefpodoxime, amoxicillin-clavulanate, TMP-SMX, nitrofurantoin
- Common IV agents: ceftriaxone (75 mg/kg/day), gentamicin, cefotaxime
- Antibiotic prophylaxis after febrile UTI remains controversial - modest reduction in recurrence must be weighed against resistance emergence - Red Book 2021
Spinal Cord Injury Patients
- High rate of colonization and overdiagnosis; symptomatic UTI must be distinguished from ASB
- Avoid treating ASB; reserve antibiotics for systemic signs - Campbell-Walsh-Wein Urology
Prostatitis (Acute Bacterial)
- Fluoroquinolones (ciprofloxacin or levofloxacin) are first-line, given excellent prostate tissue penetration
- Treat for 4-6 weeks to prevent progression to chronic bacterial prostatitis
- Recurrent UTI in men should prompt evaluation for chronic bacterial prostatitis as the source - Campbell-Walsh-Wein Urology
11. Antimicrobial Stewardship Principles
- Always consider local antibiogram data before prescribing empirically
- Reserve fluoroquinolones for complicated UTI and pyelonephritis, not routine cystitis
- Step down from IV to oral therapy as soon as clinical stability is achieved
- Do not treat ASB except in the specific indications above
- Carbapenems and alternatives for cephalosporin-resistant (ESBL-producing) gram-negative uropathogens - a 2024 systematic review and meta-analysis (PMID: 38705237) supports alternatives to carbapenems for ESBL-related complicated UTI in selected cases
