Lidocaine versus morphine for kidney stone pain
Treatments studied
Part of Kidney & urinary, Pain, Women’s health & pregnancy clinical trials.
This study compares two pain medicines, lidocaine and morphine, to see which one works better and is safer for treating sudden, severe pain from kidney stones in the emergency room. If you have already received one painkiller but still have pain, this trial may help find a better option for you.
Summary written for real people, not researchers, by Clin2.

- You must be 18 years old or older.

This study compares two ways to relieve the severe pain of a kidney stone: a small device that sends gentle electrical pulses to your skin (called TENS) and a painkiller called dexketoprofen. It may help you get safe and effective pain relief without strong side effects.
This trial compares two medicines given in the emergency department (one as a vein injection, one as a mist you breathe in) to see which works better and faster for the severe pain of kidney stones (renal colic). Participation lasts only for your emergency visit, and the goal is to improve pain relief options.
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 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 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.
This trial tests whether using a special combination of pain-relief medicines during kidney stone surgery improves your recovery and comfort afterward. It aims to reduce the need for strong opioids, which can have side effects.
