Lidocaine vs. Morphine for Kidney Stone Pain Relief
Treatments studied
Part of Kidney & urinary, Pain, Women’s health & pregnancy clinical trials.
This study compares two pain-relief medications—lidocaine (a numbing medicine) and morphine (a strong painkiller)—for people with acute kidney stone pain in the emergency department. The goal is to see which one works better when initial treatment with ketorolac (an anti-inflammatory) isn't enough.
Summary written for real people, not researchers, by Clin2.

- You are 18 years or older
- You have suspected kidney stone pain (flank, back, abdomen, or groin pain) as your main complaint
- You've already received ketorolac in the ER but still need more pain relief
- You haven't taken any pain medication for your kidney stone in the 6 hours before the ER doctor sees you

This study compares two ways to relieve kidney stone pain: a mild electrical stimulation device (TENS) and a standard painkiller (dexketoprofen). It aims to find which works better and faster, so you can get relief sooner.
This study tests whether a steroid given through an IV or a muscle-relaxing medicine given through a nebulizer works better for sudden, severe flank pain from kidney stones. You may be eligible if you have intense pain, have not taken pain medicine in the last 6 hours, and are generally healthy.
This study tests whether combining paracetamol with either tramadol or caffeine works better than a placebo for pain from kidney stones when you leave the emergency room. It aims to find a simple, effective pain reliever to take home.
This study tests whether pressing specific points on the ear, along with pain medicine, can relieve kidney stone pain faster than pain medicine alone. It's designed for people with confirmed kidney stones and moderate to severe pain who haven't taken pain relievers recently.
This study compares an anti-inflammatory pain medicine (NSAID) given by mouth versus acetaminophen (paracetamol) or placebo after you leave the emergency room for a “renal colic” (kidney stone pain). It looks at whether the NSAID helps control pain better and whether it’s safe for people with uncomplicated kidney stone pain.
This trial compares two ways to manage pain during robotic-assisted kidney or ureter surgery: a spinal injection of morphine or an intravenous infusion of lidocaine. The goal is to see which method provides better pain relief and recovery.
