Second-Choice Analgesic Management for Acute Kidney Stone Pain

Acute kidney stone pain — renal colic — is one of the most intense forms of pain encountered in clinical practice. When initial analgesic therapy is insufficient, a structured second-choice approach is required to achieve adequate pain control.

Treatment approach

In the acute setting, second-choice analgesia involves either an opioid analgesic or ketamine, with specific guidance on agent selection within each class.

The complete regimen — including which specific agents to choose or avoid and the clinical rationale for each — is available in the full protocol.

Offer opioids (hydromorphone, pentazocine or tramadol) or ketamine in the acute setting as second choice.

If an opioid is used, it is recommended that an opioid other than pethidine be used.

Compared to opioids, ketamine use in the acute setting shows a longer duration of analgesia in renal colic with satisfactory safety profile.
