Renal calculi pain is best managed with which analgesic approach?

• A. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
• B. Opioids
• C. Acetaminophen
• D. Tramadol

Answer: (A)

Renal colic pain comes from ureteral spasm and increased pressure as a stone moves through the ureter. The most effective initial analgesic is an NSAID. By blocking cyclooxygenase, NSAIDs reduce prostaglandin production in the kidney, which lowers ureteral smooth muscle tone and dampens the inflammatory response. This combination provides rapid, strong pain relief and often decreases the need for additional opioids. Alternatives like acetaminophen or tramadol offer less targeted relief for this type of pain, and opioids don’t address the underlying spasm as effectively. Use NSAIDs with caution in patients with kidney disease, peptic ulcers, or bleeding risk due to potential adverse effects.
