Summary
Trigger point injection using lidocaine offers rapid and complete relief for renal colic pain. This safe and effective method proved superior to conventional treatments, providing significant symptom improvement within minutes.
Area of Science:
- Urology
- Pain Management
- Anesthesiology
Background:
- Renal colic treatment lacks rapid and complete pain relief.
- A prospective trial evaluated trigger point injection for renal colic.
- Lidocaine trigger point injection was assessed using the visual analog scale.
Purpose of the Study:
- To evaluate the efficacy of trigger point injection for renal colic.
- To compare lidocaine trigger point injection with conventional treatment.
Main Methods:
- Sixty patients with renal colic were randomized into two groups.
- Group 1 received intravenous butylscopolamine bromide and sulpyrine.
- Group 2 received local lidocaine trigger point injection.
Main Results:
- Complete pain relief occurred in 15/30 patients post-injection.
- 50% symptom improvement averaged 9 minutes in the lidocaine group.
- Lidocaine treatment was significantly superior to conventional therapy with no observed side-effects.
Conclusions:
- Trigger point injection with lidocaine is an effective, safe, and easy method for renal colic.
- This technique offers significant advantages over intravenous butylscopolamine and sulpyrine.
