Reserve carbapenems for confirmed MDR or critically ill
Cascade susceptibility reporting guides narrowing
Source control priority
Source control is as important as antibiotics in urosepsis
Obstruction relief reduces bacterial load and bacteremia
Delayed source control associated with increased mortality
Timing principle
Most source control interventions should occur within 6-12 hours
Earlier preferred when technically feasible
Coordination between emergency medicine, urology, and IR
Simultaneous antibiotics and decompression planning
ICU-level monitoring post-procedure
Sepsis bundle adherence
Hour-1 bundle (Surviving Sepsis Campaign)
Lactate measurement
Blood cultures before antibiotics
Broad-spectrum antibiotics
30 mL/kg crystalloid for hypotension or lactate >=4 mmol/l
Vasopressors if hypotension persists after fluids
Evidence base
Bundle compliance associated with reduced mortality
ACEP Level A recommendation for sepsis bundle adherence
Patient Discharge Instructions
copy discharge instructions
Urosepsis home care after discharge
Complete the full antibiotic course as prescribed
Do not stop even if feeling better
Take with food if stomach upset occurs
Drink plenty of fluids
At least 2 litres of water per day
Avoid alcohol during antibiotic treatment
Rest and gradual return to activity
Full recovery may take 1-2 weeks
Contact your doctor before resuming strenuous activity
Follow-up appointments
Return to your family doctor or clinic within 48-72 hours
Bring your antibiotic prescription and discharge summary
Urine culture results may need to be reviewed
Urology follow-up if you had a kidney stone, stent, or drain placed
Do not miss this appointment
Your stent or drain may need removal or adjustment
Repeat urine test after completing antibiotics
Confirm infection has cleared
Usually done 5-7 days after finishing antibiotics
Warning signs to return to the emergency department immediately
Fever above 38.5 C (101.3 F) or shaking chills
Especially if not improving after starting antibiotics
Worsening pain in flank or abdomen
Unable to keep fluids or medications down
Decreased or no urine output
Confusion, unusual sleepiness, or difficulty waking
Dizziness, fainting, or feeling very weak
Shortness of breath
Worsening or not improving after 48-72 hours on antibiotics
Prevention of recurrence
Stay well hydrated every day
At least 2 litres of fluid daily
Cranberry juice does not reliably prevent infection
Urinate regularly and do not hold urine for long periods
Talk to your doctor about treating underlying causes
Kidney stones
Enlarged prostate
Recurrent urinary tract infections
