Lesson Objectives

Differentiate lower UTI/cystitis from upper UTI/pyelonephritis by cause, timeline, and assessment findings and explain WHY each finding occurs.
Explain how bacterial adherence, reflux, and obstruction lead to dysuria, frequency, urgency, suprapubic pain, fever, flank pain, and CVA tenderness.
Interpret urinalysis, urine culture, BUN/Cr, and inflammatory markers and trend them.
Prioritize care: cultures before antibiotics, fluid management, pain relief, CAUTI prevention, and sepsis recognition.
Provide patient teaching for prevention, medication adherence, and when to seek emergency care.

Why This Disease Matters

Prevalence: UTIs account for 10 million ambulatory visits and 1 million ED visits yearly in US. 50-60% of women will have at least one UTI. Cystitis most common bacterial infection in women. Pyelonephritis incidence 15-17 per 10,000 women. Recurrence 20-30% within 6 months.

Patient safety: Untreated cystitis can ascend to pyelonephritis → urosepsis → septic shock, especially in pregnancy, elderly, diabetics, obstruction, catheters. Elderly may present only with confusion, fall, hypotension — missed until septic. Pregnancy pyelonephritis → preterm labor. Phenazopyridine masks hematuria and can cause methemoglobinemia if overused.

NCLEX importance: High-yield every exam. Cystitis: frequency + urgency + dysuria + suprapubic pain + low-grade fever or no fever, no CVA tenderness, positive leukocyte esterase/nitrites. Pyelonephritis: fever + chills + flank pain + CVA tenderness + N/V + tachycardia. Cultures BEFORE antibiotics, clean catch midstream technique, bladder scan before straight cath, increase fluids 2-3L if not contraindicated, CAUTI prevention no Foley unless indicated sterile insertion bag below bladder remove ASAP.

Why nurses encounter them: Every setting — clinic, ED, med-surg, ICU, LTC, OB, post-op with catheters. Indwelling Foley is #1 risk factor for CAUTI, most common healthcare-associated infection.

Connecting to prior lessons From A&P: Urinary tract kidneys → ureters → bladder → urethra, female urethra short 3-4cm close to vagina/anus → higher cystitis risk, male urethra longer but BPH causes retention. Detrusor contracts to void. From assessment: CVA tenderness at costovertebral angle 12th rib, suprapubic tenderness cystitis, I&O hourly, daily weight, urine color/clarity/odor, bladder scan for retention vs oliguria, perineal hygiene, vitals fever/hypotension sepsis.

Disease Overview

Condition	Definition	Location	Core problem
UTI general	Bacteria in urinary tract causing infection/inflammation	Anywhere	Bacteria E. coli 75-95% adhere and multiply → inflammation
Cystitis lower UTI	Infection/inflammation of bladder	Lower tract	Bladder mucosa inflamed → urgency frequency dysuria suprapubic pain usually afebrile no CVA tenderness
Pyelonephritis upper UTI	Infection/inflammation of kidney and renal pelvis	Upper tract	Bacteria ascend via ureters or bloodstream → kidney parenchyma inflamed → fever chills flank pain CVA tenderness N/V sepsis risk

Pathophysiology

Normal: Urine sterile in kidneys/bladder, flows one-way down ureters, ureterovesical junction prevents reflux, bladder stores 300-500mL, detrusor contracts sphincter relaxes to void. Regular voiding flushes bacteria, acidic urine, intact mucosal defenses. ↓ Cystitis — What goes wrong: E. coli from GI tract colonizes perineum → ascends short female urethra to bladder. Sexual intercourse pushes bacteria up, spermicides alter flora, holding urine allows multiplication, dehydration concentrates bacteria, catheters bypass defenses. Bacteria adhere to bladder wall via fimbriae → inflame mucosa → detrusor irritability → urgency sudden need, frequency small amounts often, dysuria burning inflamed urethra, suprapubic pain bladder spasm, hematuria friable mucosa, cloudy foul urine WBCs/bacteria. Usually NO fever or low-grade because localized below kidneys, NO CVA tenderness. ↓ Pyelonephritis — What goes wrong: Cystitis bacteria ascend ureters to kidney pelvis especially if vesicoureteral reflux or obstruction stones/BPH/pregnancy progesterone relaxes ureters + uterus compresses. Or hematogenous spread bacteremia seeds kidneys. Bacteria invade kidney parenchyma and tubules → inflammation → WBC casts WHY casts: WBCs mold in tubules, tubular dysfunction → decreased concentrating ability, fever high from cytokines, chills, flank pain kidney capsule stretch, CVA tenderness fist percussion, N/V, tachycardia/tachypnea, risk bacteremia → urosepsis → septic shock hypotension/oliguria. ↓ Progression: Untreated cystitis → pyelonephritis → renal scarring if recurrent especially children → CKD. Pyelonephritis → urosepsis → AKI. Pregnancy pyelonephritis → preterm contractions.

Risk Factors

Non-modifiable	Modifiable / Preventable	High-risk populations
Female anatomy short urethra, postmenopausal estrogen low, age elderly and infant, pregnancy, history childhood UTIs with vesicoureteral reflux, urinary tract anomalies	Dehydration low fluid intake, holding urine, sexual activity, spermicide/diaphragm, poor perineal hygiene wiping back to front, indwelling catheter #1 modifiable hospital risk, urinary retention BPH/constipation/neurogenic bladder, kidney stones obstruction, tight synthetic underwear, bubble baths, diabetes, obesity, fecal incontinence	Women 50-60% lifetime, sexually active young women honeymoon cystitis, postmenopausal women, pregnant persons 2nd trimester onward, diabetics, elderly in LTC, ICU with Foley, spinal cord injury neurogenic bladder, BPH men, kidney stones, immunocompromised

Signs and Symptoms

Category	Finding & WHY
Early — cystitis lower	Urgency sudden need (WHY bladder irritability), frequency q20-30min small amounts (WHY inflamed bladder cannot hold), dysuria burning (WHY inflamed urethra), suprapubic pressure/pain (WHY bladder spasm), cloudy foul urine (WHY WBCs/bacteria), slight hematuria pink-tinged (WHY friable mucosa). No or low-grade fever <100.4°F, no flank pain, no CVA tenderness.
Early — pyelonephritis upper	Fever high 101-103°F chills (WHY systemic cytokines), flank pain unilateral/bilateral (WHY kidney capsule stretch), CVA tenderness positive (WHY kidney inflammation), nausea/vomiting (WHY shared innervation and uremia), malaise, dysuria may still be present.
Expected	Cystitis: frequency urgency dysuria suprapubic tenderness cloudy foul low-grade fever or afebrile. Pyelonephritis: all cystitis PLUS high fever chills flank pain CVA tenderness N/V tachycardia WBC casts.
Unexpected / Atypical	Elderly: confusion agitation fall new incontinence low-grade fever or no fever hypotension only sign — blunted immune response. Pregnancy: contractions back pain mistaken for labor. Children: fever irritability poor feeding bedwetting new.
Emergency	Urosepsis: fever + tachy >100 + tachypnea >22 + hypotension <90 + altered mental + oliguria <30 + flank pain + CVA tenderness, severe N/V rigors lactate >2. Obstruction: anuria + rising Cr + severe flank colicky radiating to groin + hematuria.

Diagnostic Tests

Test	Purpose / Findings / Nursing
Urinalysis dipstick + microscopy	Leukocyte esterase positive WBCs, nitrites positive bacteria reduce nitrate to nitrite E. coli, RBCs hematuria, WBCs + WBC casts pyelo kidney, protein trace, specific gravity high dehydrated low dilute pyelo cannot concentrate. Prep clean catch midstream front to back midstream catch. Abnormal cloudy + positive leuk esterase/nitrites/RBCs/WBCs/WBC casts.
Urine culture and sensitivity	Gold standard organism + antibiotics. >100k CFU/mL single organism classic but symptomatic lower counts 10k still infection especially pyelo. WBC casts upper tract. Prep clean catch midstream or straight cath per protocol before antibiotics.
Blood cultures if pyelo/fever/sepsis	Detect bacteremia urosepsis. Draw 2 sets different sites BEFORE antibiotics. Fever + flank pain + hypotension blood cultures STAT.
Bladder scan, Renal ultrasound, CT non-contrast for stone if obstruction suspected	Bladder scan residual >100 abnormal >200 retention vs oliguria true kidney problem. Ultrasound hydronephrosis obstruction. CT without contrast stone gold standard. Nursing bladder scan before straight cath per protocol.

Laboratory Tests

Lab	Purpose / Normal / Abnormal
Urinalysis: leukocyte esterase negative, nitrites negative, RBC 0-3/hpf, WBC 0-5/hpf	Leuk esterase positive WBCs infection, nitrites positive bacteria E. coli but not all bacteria make nitrites so negative does not rule out, RBCs hematuria cystitis, WBCs + WBC casts pyelo kidney. Trend leuk esterase should become negative with treatment.
Urine culture >100k CFU/mL	Organism + sensitivity E. coli most common. Trend repeat culture 1-2 weeks after if recurrent/pyelo.
CBC: WBC 5-10k, BUN 7-20, Cr 0.6-1.2, Lactate 0.5-1.5	WBC high infection higher in pyelo than cystitis, BUN/Cr may rise if pyelo with AKI/obstruction, lactate >2 sepsis. Cystitis often WBC normal or mildly high. Priority rising Cr + oliguria AKI.

Medications

Class / Meds	Mechanism & Nursing
Antibiotics cystitis: Nitrofurantoin (Macrobid), Trimethoprim-sulfamethoxazole (Bactrim), Fosfomycin	Nitrofurantoin damages bacterial DNA in bladder, TMP-SMX inhibits folate. Indication uncomplicated cystitis. Contra nitrofurantoin if CrCl <30 near term pregnancy, TMP-SMX sulfa allergy. Side nausea brown urine expected peripheral neuropathy rare, TMP-SMX rash hyperkalemia. Nursing cultures BEFORE first dose, with food, fluids 2-3L if not contraindicated, finish full course, monitor C. diff, teach.
Pyelonephritis: Fluoroquinolones Cipro/Levo, Ceftriaxone — 7-14 days	Cipro inhibits DNA gyrase. Black box tendinitis/tendon rupture peripheral neuropathy CNS aortic dissection risk avoid in pregnancy/children if alternative. Side GI upset photosensitivity QT prolongation. Nursing cultures before antibiotics, full glass water avoid antacids/iron/calcium within 2hr, monitor tendons, fluids, finish course, C. diff.
Phenazopyridine (Pyridium) short-term 2 days max	Local anesthetic urinary tract relieves burning. Orange-red urine expected stains clothes contacts methemoglobinemia if overused. Teach orange-red expected does NOT treat infection take with food limit 2 days report yellow skin remove contacts.

Nursing Interventions

Priority	Intervention & WHY
Circulation / Sepsis	Vitals q4h or q15min if pyelo/sepsis orthostatics, blood/urine cultures BEFORE antibiotics if pyelo/fever/sepsis STAT antibiotics within 1hr if hypotensive, I&O hourly if oliguria/sepsis daily weight fluids 2-3L/day if not contraindicated HF/CKD flush bacteria prevent stasis, bladder scan if anuria differentiate retention vs true oliguria, monitor lactate BUN/Cr.
Safety — CAUTI	Hand hygiene #1, perineal care front to back, no Foley unless indicated sterile insertion secure bag below bladder never on floor remove ASAP daily review avoid kinks, clean catch technique front to back midstream not from bedpan, avoid spermicides diaphragms bubble baths tight synthetic underwear.
Comfort	Pain 0-10 dysuria suprapubic flank, warm sitz bath, phenazopyridine short-term 2 days teach orange urine expected, increase fluids dilute urine reduces burning, void frequently don't hold, avoid caffeine/alcohol/spicy irritate bladder.

Potential Complications

Complication	Early signs	Response
Pyelonephritis ascending	Fever high chills flank pain CVA tenderness N/V WBC casts	Cultures blood/urine before antibiotics vitals I&O fluids antibiotics 7-14 days BUN/Cr
Urosepsis septic shock	Fever/hypothermia tachy >100 tachypnea >22 hypotension <90 altered mental oliguria <30 lactate >2	Rapid response O2 large-bore IV 30mL/kg if sepsis cultures before antibiotics STAT antibiotics within 1hr lactate trend vasopressors
AKI from obstruction/sepsis	Oliguria <30 x6h anuria <100/24h rising BUN/Cr edema weight gain crackles	Bladder scan rule out retention vs true oliguria check Foley kinks/clots I&O hourly daily weight hold nephrotoxins notify STAT US/CT obstruction

Patient Education

Cystitis lower frequency urgency dysuria suprapubic pain cloudy foul low/no fever NO CVA. Pyelo upper high fever chills flank pain CVA tenderness N/V sepsis risk.
Drink 2-3L water/day if not contraindicated, void q2-3hr don't hold, void after intercourse, wipe front to back, cotton underwear, avoid spermicides/bubble baths/tight synthetic, no douching.
Finish full antibiotic even if better in 2 days, with food if GI upset avoid antacids/iron/calcium within 2hr of fluoroquinolones, fluids, report rash/diarrhea. Phenazopyridine only 2 days orange-red urine expected stains does NOT treat infection.
Repeat urine culture 1-2 weeks after if recurrent/pyelo, urology if >3 UTIs/year.
Emergency: high fever >101 chills flank pain CVA tenderness N/V confusion hypotension oliguria <30 anuria severe suprapubic pain hematuria with clots inability to void contractions in pregnancy no improvement in 2-3 days on antibiotics.

Clinical Judgment

Recognize: 24yo female 2 days frequency q20min urgency dysuria burning suprapubic pressure cloudy foul 80mL no flank pain no CVA tenderness Temp 99.2 low-grade holds urine at work low fluid intake sexually active new partner spermicide. Now Temp 101.6 chills left flank pain dull nausea sexually active spermicide HR 102 BP 100/64 RR 22 suprapubic tenderness present left CVA positive now cloudy foul pink-tinged I&O decreased bladder scan 90mL post-void.
Analyze: Initially cystitis lower frequency urgency dysuria suprapubic cloudy foul low/no fever no CVA now progression to pyelonephritis upper fever 101.6 chills flank pain CVA N/V tachy borderline hypo.

NCLEX Practice Questions

Final check: Answers spread across numbers, no two identical consecutive answers, no 1-2-3-4-5 sequential order. SATA combos randomized.

1. A young woman reports frequency, urgency, dysuria, suprapubic pressure, cloudy foul urine, low-grade fever 99.4°F, no flank pain, no CVA tenderness. What does the nurse suspect?

Pyelonephritis with flank pain and CVA tenderness
Urethritis with purulent discharge and lesions
Uncomplicated cystitis lower UTI with frequency urgency dysuria suprapubic pain and no CVA tenderness
Asymptomatic bacteriuria with no symptoms

Rationale

Answer: 3. Why 3 correct: Cystitis lower: frequency urgency dysuria suprapubic pressure cloudy foul low or no fever NO CVA tenderness no flank pain — bladder mucosa inflamed. Why others wrong: 1. Pyelo high fever chills flank pain CVA tenderness N/V WBC casts kidney involvement. 2. Urethritis/STI discharge lesions sexual history. 4. Asymptomatic bacteriuria no symptoms positive culture treat only if pregnant or urologic procedure.

2. A client has fever 101.8°F chills left flank pain CVA tenderness positive nausea vomiting dysuria tachycardia. Which action is priority?

Obtain blood and urine cultures before antibiotics and notify provider STAT for pyelonephritis possible urosepsis
Encourage 500mL water and discharge home
Give phenazopyridine only and teach orange urine expected
Insert Foley without assessment

Rationale

Answer: 1. Why 1 correct: High fever chills flank pain CVA tenderness N/V tachy = pyelonephritis upper UTI risk urosepsis. Need blood and urine cultures BEFORE antibiotics STAT, vitals q15min-1h I&O hourly lactate BUN/Cr, fluids 2-3L if not contraindicated, antibiotics within 1hr if sepsis 7-14 days. WHY cultures first: antibiotics sterilize and lose organism. Why others wrong: 2. Discharge unsafe — needs cultures and antibiotics, may be septic. 3. Phenazopyridine only does not treat infection, only 2 days relief. 4. Foley without assessment not indicated CAUTI risk — bladder scan first.

3. A client is prescribed nitrofurantoin for cystitis and phenazopyridine for dysuria. Which teaching is correct?

Stop antibiotics when feeling better after 2 days and continue phenazopyridine for 2 weeks
Take both medications on empty stomach and expect clear urine
Avoid fluids to prevent frequency
Take nitrofurantoin with food finish full course even if feeling better, take phenazopyridine with food only 2 days max orange-red urine expected stains clothes and contacts does not treat infection

Rationale

Answer: 4. Why 4 correct: Nitrofurantoin with food finish full course 5 days even if better prevents resistance/recurrence, phenazopyridine with food only 2 days max for burning relief orange-red urine expected stains clothes/contacts does NOT treat infection, report yellow skin. Why others wrong: 1. Stop early causes recurrence/resistance, phenazopyridine 2 weeks causes methemoglobinemia. 2. Empty stomach clear urine false — nitrofurantoin with food and orange urine expected. 3. Avoid fluids worsens infection — need 2-3L if not contraindicated to flush bacteria.

4. An elderly client in long-term care has new confusion fall incontinence low-grade fever no dysuria. What should the nurse do?

Document as expected aging and do not notify provider
Assess vitals orthostatics I&O daily weight urine characteristics bladder scan, obtain urine culture per protocol, notify provider, assess for urosepsis hypotension oliguria
Encourage caffeine to improve alertness
Place indwelling Foley for incontinence

Rationale

Answer: 2. Why 2 correct: Elderly UTI may present only as new confusion/fall/incontinence low-grade fever without dysuria due to blunted immune response. Need vitals orthostatics I&O daily weight bladder scan urine cloudy foul culture before antibiotics, notify provider assess for urosepsis hypotension tachy oliguria lactate. Why others wrong: 1. Expected aging misses sepsis — confusion new is red flag. 3. Caffeine irritates bladder worsens frequency. 4. Foley for incontinence increases CAUTI risk not indicated.

5. Which preventive teaching is correct for recurrent cystitis?

Drink 2-3L water/day if not contraindicated, void q2-3hr don't hold, void after intercourse, wipe front to back, cotton underwear, avoid spermicides bubble baths tight synthetic underwear, avoid caffeine/alcohol
Wipe back to front and hold urine for 6 hours
Take cranberry juice to treat active infection and stop antibiotics
Use bubble baths daily to clean perineum

Rationale

Answer: 1. Why 1 correct: Prevention fluids 2-3L flush bacteria, void q2-3hr don't hold, void after intercourse flush bacteria pushed up, wipe front to back prevents GI bacteria to urethra, cotton underwear, avoid spermicides/diaphragms/bubble baths/tight synthetic irritate, avoid caffeine/alcohol irritate bladder. Why others wrong: 2. Wipe back to front hold urine increases risk. 3. Cranberry may reduce recurrence but does NOT treat active infection do not stop antibiotics. 4. Bubble baths irritate urethra increase risk.

6. SATA. Which findings support pyelonephritis rather than cystitis? Select all that apply.

High fever 102°F chills flank pain CVA tenderness nausea vomiting WBC casts in urine
Frequency urgency dysuria suprapubic pain cloudy foul urine low-grade or no fever no CVA tenderness
Positive blood cultures with same organism as urine culture and WBC 15k high
Orange-red urine after phenazopyridine with no pain
Tachycardia tachypnea borderline hypotension oliguria

Rationale

Answers: 1, 3, 5. Why these: Pyelo upper: high fever chills flank pain CVA tenderness N/V WBC casts = kidney involvement tubular WBCs mold, positive blood cultures bacteremia same organism as urine WBC high, tachy tachypnea borderline hypo oliguria early urosepsis. Why others wrong: 2. Frequency urgency dysuria suprapubic low/no fever no CVA = cystitis lower. 4. Orange-red urine after phenazopyridine expected from analgesic not infection.

7. SATA. Which are appropriate for CAUTI prevention? Select all that apply.

Insert Foley for incontinence without medical indication and leave indefinitely
Obtain urine culture from bag not sampling port and disconnect tubing frequently
Maintain sterile insertion technique secure catheter keep bag below bladder never on floor perform perineal hygiene daily review necessity and remove ASAP
Perform bladder scan before straight catheterization per protocol and avoid kinks in tubing encourage fluids if not contraindicated
Encourage fluids if not contraindicated and daily necessity check

Rationale

Answers: 3, 4, 5. Why these: CAUTI prevention sterile insertion secure bag below bladder never floor perineal hygiene daily necessity review remove ASAP, bladder scan before straight cath per protocol avoid kinks, fluids if not contraindicated encourage daily necessity check. Why others wrong: 1. Inserting for incontinence without indication leave indefinitely increases CAUTI. 2. Culture from bag disconnect tubing contaminated use sampling port sterile.

8. Priority. The nurse has four clients. Who should be seen first?

Client with cystitis frequency urgency dysuria suprapubic pressure afebrile stable vitals
Client with dark amber urine after low fluid intake stable vitals
Client with fever 102°F flank pain CVA tenderness nausea vomiting BP 86/58 HR 118 cloudy foul urine oliguria 20mL/hr
Client with BPH weak stream nocturia voiding 200mL no distress

Rationale

Answer: 3. Why 3 first: Fever 102 + flank pain + CVA + N/V + hypotension 86/58 + tachy 118 + oliguria 20mL/hr = pyelonephritis with urosepsis emergency needs STAT cultures before antibiotics antibiotics within 1hr fluids 30mL/kg per sepsis protocol rapid response. Why others later: 1. Cystitis stable routine. 2. Dark amber low intake stable dehydration routine fluids. 4. BPH weak stream voiding no distress stable.

9. Delegation. Which task can the RN delegate to LPN/VN for a client with uncomplicated cystitis?

Assess CVA tenderness and interpret urine culture
Teach initial diagnosis and prescribe antibiotics
Manage urosepsis with hypotension and oliguria
Check vitals I&O daily weight bladder scan per protocol report dysuria frequency suprapubic pain fever flank pain CVA tenderness and give nitrofurantoin per order with teaching per plan

Rationale

Answer: 4. Why 4 delegatable: LPN/VN can check vitals I&O daily weight bladder scan per protocol report dysuria frequency suprapubic pain fever flank pain CVA tenderness give PO antibiotics per order reinforce teaching fluids/hygiene per plan. Why others RN only: 1. Assessing CVA interpreting culture RN. 2. Teaching initial diagnosis prescribing antibiotics provider/RN. 3. Managing urosepsis hypotension oliguria RN rapid.

10. NGN Case Study. A 30-year-old pregnant person 22 weeks reports 3 days dysuria frequency urgency suprapubic pressure cloudy foul urine now fever 101.8°F chills left flank pain CVA tenderness positive nausea vomiting. Vitals HR 108 BP 98/62 RR 22 Temp 101.8°F SpO2 96% RA, UA leuk esterase/nitrites positive WBCs WBC casts present, urine culture pending, BUN/Cr slightly high, fetal heart rate 148. No contractions yet but back pain.

a) What condition and cues support it? b) What are 3 priority actions and why? c) What indicates improvement and what teaching to prevent recurrence?

Model answer

a) Pyelonephritis in pregnancy: Pregnant 22 weeks + dysuria frequency urgency suprapubic pressure cloudy foul cystitis now high fever 101.8 chills flank pain CVA tenderness N/V tachy borderline hypo = upper UTI pyelonephritis ascending, UA leuk esterase/nitrites + WBCs + WBC casts = kidney involvement, pregnancy risk progesterone relaxes ureters + uterus compresses → reflux + stasis. Risk preterm labor low birth weight.

b) Priorities: 1) Cultures blood and urine BEFORE antibiotics STAT + notify OB/provider STAT, vitals q15min-1h orthostatics I&O hourly daily weight lactate BUN/Cr WBC, sepsis screen. 2) Antibiotics safe in pregnancy per order after cultures 7-14 days, fluids 2-3L if not contraindicated per OB, antipyretic per order, monitor FHR and contractions, tocolytics per order if preterm labor, no NSAIDs in pregnancy especially 3rd trimester. 3) Education fluids 2-3L void q2-3hr don't hold void after intercourse wipe front to back cotton underwear avoid spermicides, adherence finish full course, when to seek emergency high fever + flank + CVA + N/V + hypotension + oliguria + contractions/bleeding/fluid loss.

c) Improvement: Temp 101.8→99°F, HR 108→88, BP 98/62→110/70, flank pain CVA tenderness decreased, N/V resolved, dysuria improved, urine clear not cloudy foul, WBC down, BUN/Cr stable, lactate <2, FHR 148 stable no contractions, UOP adequate. Teaching finish full antibiotics even if better, fluids 2-3L, void q2-3hr don't hold, void after intercourse, wipe front to back, cotton underwear, avoid spermicides bubble baths tight synthetic, follow-up culture 1-2 weeks to confirm clearance, OB follow-up, when to seek emergency fever + flank + CVA + N/V + hypotension + contractions/bleeding/fluid loss preterm risk, no self-treat with cranberry alone.

Key Takeaways

Cystitis lower: frequency + urgency + dysuria + suprapubic pain + cloudy foul + low/no fever + NO CVA tenderness. Pyelo upper: all lower PLUS high fever chills + flank pain + CVA tenderness + N/V + WBC casts = kidney.
Cultures BEFORE antibiotics: urine clean catch midstream front to back midstream, blood cultures if pyelo fever/sepsis before antibiotics STAT, antibiotics within 1hr if sepsis.
Fluids 2-3L/day if not contraindicated to flush bacteria, void q2-3hr don't hold, void after intercourse, wipe front to back, cotton underwear, avoid spermicides/bubble baths/tight synthetic.
Phenazopyridine orange-red urine expected stains 2 days max does NOT treat infection.
Elderly confusion/fall/incontinence/hypotension may be only UTI sign → vitals I&O bladder scan cultures before antibiotics sepsis screen.
CAUTI prevention: no Foley unless indicated sterile insertion secure bag below bladder never floor perineal hygiene remove ASAP daily review bladder scan before straight cath.
