🚽 Pyelonephritis Progression & IV Antibiotic Escalation Simulator

Simple Cystitis — The Starting Point

Placeholder: bladder-only infection, mild symptoms, oral therapy usually sufficient.

• E. coli: Typical pathogen (Placeholder short note)
• Oral: First-line route (Placeholder short note)
• Rare: Fever present (Placeholder short note)
• 3–5 days: Course length (Placeholder short note)

Bladder-confined infection basics

Placeholder short paragraph describing simple cystitis mechanics.

Ascending Infection to the Kidney

Placeholder: bacteria ascend ureters, reaching renal pelvis and parenchyma.

• Ureters: Ascent route (Placeholder short note)
• Reflux, stasis: Risk factors (Placeholder short note)
• Hours-days: Onset (Placeholder short note)
• Renal swelling: Imaging clue (Placeholder short note)

How infection climbs to the kidney

Placeholder short paragraph describing ascending infection pathway.

Fever and Flank Pain Onset

Placeholder: systemic fever and costovertebral angle tenderness emerge.

• >38.5°C: Fever threshold (Placeholder short note)
• Flank/CVA: Pain site (Placeholder short note)
• Common: Nausea (Placeholder short note)
• Same-day eval: Urgency (Placeholder short note)

Recognizing systemic pyelonephritis signs

Placeholder short paragraph describing fever and flank pain findings.

Sepsis Warning Signs

Placeholder: tachycardia, hypotension, confusion mark systemic spread.

• ≥2 signs: qSOFA cue (Placeholder short note)
• >90 bpm: Heart rate (Placeholder short note)
• Falling: BP trend (Placeholder short note)
• Altered: Mental status (Placeholder short note)

Spotting early urosepsis

Placeholder short paragraph describing sepsis warning progression.

Oral to IV Antibiotic Transition

Placeholder: severity crossing threshold triggers switch to IV antibiotics.

• Severity >55%: Switch trigger (Placeholder short note)
• Ceftriaxone: IV first-line (Placeholder short note)
• Often required: Admission (Placeholder short note)
• 24–48h: Reassessment (Placeholder short note)

Deciding the IV escalation moment

Placeholder short paragraph describing the oral-to-IV switch decision.

Placeholder: escalate to IV promptly once sepsis signs or high fever appear.
