Post operative pain after URS is usually treated with opioids and non steroidal anti inflammatory drugs. Intranasal ketorolac (SprixTM) is an FDA approved pain formulation for short term management (5 days) of moderate to moderately severe pain that requires analgesia at the opioid level. The efficacy of intranasal ketorolac formulation was demonstrated in placebo-controlled studies in patients following major surgeries.
