This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Guideline: Management of ureteral calculi. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Assess for infection, acute kidney injury, solitary kidney, uncontrolled symptoms and obstruction requiring urgent decompression.
  • Use appropriate imaging and symptom control while avoiding delay when an infected obstructed system is possible.
  • Base observation, medical expulsive therapy and intervention on stone size, location, complications and local urology access.
  • Arrange stone analysis and targeted metabolic prevention after recurrent or high-risk stone disease.

Practical assessment and management workflow

1
Assess pain, fever, urine output, pregnancy, solitary kidney and previous stone history.
2
Obtain urinalysis, renal function and ultrasound or CT chosen for the clinical context.
3
Provide analgesia and decide observation versus urologic intervention from size, site and complication status.
4
Confirm passage or relief of obstruction and offer recurrence-prevention assessment.

Safety, red flags and urgent escalation

  • Urgently decompress an infected obstructed collecting system; antibiotics alone are insufficient.
  • Escalate anuria, bilateral obstruction, solitary-kidney obstruction or uncontrolled symptoms.
  • Avoid NSAIDs when kidney injury, significant bleeding risk or another contraindication is present.
