What side effects are associated with this type of intervention?

Common treatments for kidney stones include ureteroscopy with stent placement, extracorporeal shock wave lithotripsy (ESWL), and medications like alpha-blockers and pain relievers. Ureteroscopy with stent placement can cause discomfort, urinary tract infections, and hematuria. ESWL may lead to bruising, pain, and hematuria. Alpha-blockers can cause dizziness, fatigue, and hypotension. Pregabalin, used for pain management, can cause dizziness, somnolence, dry mouth, and peripheral edema. These side effects should be discussed with a healthcare provider to determine the best treatment plan.

What prior FDA approvals exist?

The FDA has approved various treatments for kidney stones, primarily focusing on pain management and facilitating stone passage. While pregabalin itself is not specifically approved for kidney stones, it is being studied for its potential to reduce pain associated with ureteroscopy and stent placement, which are common procedures for kidney stones. Pregabalin works by binding to the alpha-2-delta subunit of voltage-gated calcium channels, reducing excitatory neurotransmitter release and decreasing pain perception. Other pain management options for kidney stones include NSAIDs and opioids, but these do not share the same mechanism of action as pregabalin.

What other types of research exist?

Promising alternatives to Pregabalin for kidney stone pain management include Gabapentin, which also binds to the alpha-2-delta subunit of voltage-gated calcium channels, and PD-0200347, an alpha-2-delta ligand shown to inhibit pathways involved in pain and inflammation. Additionally, non-pharmacological options like transcutaneous electrical nerve stimulation (TENS) may offer pain relief by modulating pain signals.

Pregabalin for Postoperative Pain After Ureteroscopy

Q: What is the mechanism of action of this treatment?

Pregabalin, a common treatment for managing pain associated with kidney stones, works by binding to the alpha-2-delta subunit of voltage-gated calcium channels. This action reduces the release of excitatory neurotransmitters, thereby decreasing pain perception. This mechanism is crucial for kidney stone patients as it helps alleviate the significant pain caused by the passage of stones, improving patient comfort and quality of life during treatment.

Summary

This trial tests if pregabalin, taken before surgery, can reduce the need for painkillers in patients having a specific type of surgery. Pregabalin works by calming nerve activity to lessen pain and anxiety. Pregabalin is a medication that is effective for treating postoperative pain, nerve pain, anxiety, and blood pressure issues. The study aims to see if this approach can help patients feel less pain after surgery.

Who is the study for?

This trial is for adults over 18 who are having elective ureteroscopy with stent placement and can consent in English. It's not for those hospitalized, pregnant, allergic to gabapentinoids, with liver or severe kidney issues, long-term stent use, chronic opioid or gabapentinoid use, or a history of abuse of these substances.

What is being tested?

The study tests if a single dose of pregabalin before surgery reduces the need for pain meds after ureteroscopy compared to a placebo. Participants won't know which they received until the end and will get gift certificates for survey completion.

What are the potential side effects?

Pregabalin may cause dizziness, sleepiness, blurred vision, weight gain, difficulty concentrating or swelling hands/feet. Not everyone will experience these side effects and they vary from person to person.
