What Is the First-Line Treatment for Acute Renal Colic?

Clinical Scenario

Renal colic causes acute, severe flank pain that demands prompt clinical attention. Immediate analgesia is the central priority — managing pain quickly is the first goal of care.

Pain relief is the priority in the acute management of renal colic.
Nonsteroidal anti-inflammatory drugs (e.g., ketorolac, 30 to 60 mg intramuscularly) are more effective and have fewer adverse effects than opioids.
Patients with well-controlled pain and no significant degree of hydronephrosis have only partial obstruction and can be followed for about four to six weeks.
