A 72-year-old woman with a history of recurrent nephrolithiasis presents to the emergency department with acute right flank pain, rigors, and altered mental status. Her temperature is 39.4°C (102.9°F), blood pressure is 85/50 mm Hg, heart rate is 122/min, and respiratory rate is 24/min. Physical examination reveals pronounced right costovertebral angle tenderness. Arrange the following management steps in the most appropriate chronological sequence for this patient.
- 1Obtain blood cultures and a urine sample for culture.
- 2Administer broad-spectrum intravenous antibiotics and a 30 mL/kg crystalloid fluid bolus.
- 3Obtain a non-contrast CT scan of the abdomen and pelvis.
- 4Consult urology for urgent decompression of the renal collecting system.
Answer
The correct sequence is: obtain cultures, administer antibiotics and fluids, perform a CT scan, and then consult urology for decompression.
The correct sequence aligns with the Surviving Sepsis Campaign guidelines and principles of surgical source control. Cultures must be drawn first to guide later targeted therapy. This is immediately followed by life-saving medical resuscitation (intravenous fluids and broad-spectrum antibiotics) within the first hour. Once the patient is hemodynamically stable enough for transport, a non-contrast CT scan is performed to confirm the anatomical cause of the urosepsis (an obstructing stone). Finally, with the diagnosis and location confirmed, urology is consulted to perform an emergent decompression, as an infected obstructed kidney is a closed space infection that cannot be cured with antibiotics alone.
Step-by-Step Solution
Key Concept
The management of urosepsis with suspected obstruction requires a strict clinical sequence: immediate cultures, prompt fluid and antibiotic resuscitation, diagnostic imaging once hemodynamically stable, and emergent urologic decompression for source control.
