What is the purpose of this trial?

This trial tests whether intravenous magnesium can reduce bladder spasms after urologic surgery. Participants will receive either magnesium (a mineral supplement) or a placebo (a harmless substance with no treatment effect) during their surgery. The trial is best suited for those undergoing a bladder procedure at the Mayo Clinic's Gonda 7 Outpatient Procedure Center. Individuals with conditions such as ongoing heart rhythm issues, kidney problems, or muscle weakness might not qualify. The researchers aim to determine if magnesium eases spasms, making recovery more comfortable. As a Phase 2 trial, this research measures magnesium's effectiveness in an initial, smaller group, allowing participants to contribute to important medical advancements.

Do I need to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are taking a calcium channel blocker, you may not be eligible to participate.

Is there any evidence suggesting that intravenous magnesium is likely to be safe for humans?

Research has shown that magnesium is generally safe for treating bladder spasms. In previous studies, patients who took magnesium experienced less bladder discomfort after surgery. For instance, one study found that magnesium reduced catheter-related issues and increased patient satisfaction. Another study demonstrated that using magnesium during surgery did not lead to additional complications in common bladder surgeries. This suggests magnesium is safe in these situations. Although not yet officially approved for bladder spasms, its use in other medical areas supports its safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about magnesium for bladder spasms because it offers a new approach by using magnesium's muscle-relaxing properties to target the spasms directly. Unlike standard treatments like anticholinergics or muscle relaxants, which can have systemic side effects, magnesium is introduced intravenously during surgery for a more targeted effect. This method could potentially reduce side effects and improve recovery times, making it a promising alternative for patients undergoing urological surgery.

What evidence suggests that magnesium might be an effective treatment for bladder spasms?

Research has shown that magnesium might help ease bladder spasms after urologic surgery. One study found that patients who took magnesium experienced less bladder discomfort from catheters. Another study discovered that magnesium reduced bladder spasms. In this trial, participants in the Magnesium Group will receive intravenous magnesium during surgery to evaluate its effectiveness. These findings suggest that magnesium could be a promising treatment for bladder problems after surgery. ^{1 2 6 7 8}

Are You a Good Fit for This Trial?

This trial is for individuals undergoing bladder procedures at Mayo Clinic Gonda 7 Outpatient Center, who are not pregnant, don't have severe kidney issues or a high magnesium level, can consent to the study, and aren't allergic to magnesium. People with muscle weakness conditions like Myasthenia gravis, those on calcium channel blockers, with ongoing atrial fibrillation or heart problems should not participate.

Inclusion Criteria

Be undergoing a bladder invasive procedure with or without planned urinary catheter on Mayo Clinic Gonda 7 Outpatient Procedure Center.

Exclusion Criteria

Are undergoing emergency surgery.

You have high levels of magnesium in your blood.

You have kidney problems with a very low glomerular filtration rate, which could cause magnesium levels in your blood to increase too much.

The compounds synthesized, including [Mg{In(SC{O}Ph)4}2] and [Ca(H2O)x{In(SC{O}Ph)4}2], were characterized using X-ray crystallography, revealing distinct structural features such as distorted octahedral coordination around Mg(II) and Ca(II) ions.

Thermal decomposition of these compounds leads to the formation of MIn2S4 materials, which was confirmed through X-ray powder diffraction, indicating potential applications in materials science.

The novel boron-centered non-nucleophilic electrolyte (BMCM) for magnesium batteries shows excellent electrochemical performance, including a low overpotential of approximately 139 mV and a high Coulombic efficiency of about 97%.

BMCM demonstrates long-term cycling stability of over 500 hours and good compatibility with CuS cathodes, making it a promising and cost-effective option for the commercialization of rechargeable magnesium batteries.

In a study involving 7 normal subjects and 4 patients with recurrent calcium oxalate kidney stones, magnesium citrate and magnesium oxide increased urinary magnesium and citrate levels, but only when taken with meals, leading to a decrease in urinary oxalate and improved urinary saturation of calcium oxalate.

The findings suggest that for magnesium supplements to effectively help manage recurrent calcium oxalate nephrolithiasis, they should be taken with meals to enhance their efficacy in reducing stone formation.

In a study of 90 patients with acute renal colic, magnesium sulfate was found to be a safe adjunct treatment for pain control, showing similar effectiveness to morphine in reducing pain scores over time.

While both magnesium sulfate and morphine achieved a high success rate in pain reduction, morphine provided quicker relief, with more patients being pain-free at the 20-minute mark, although both treatments were equally effective by 30 minutes.

In a study of 120 patients undergoing transurethral resection of bladder tumor, intravenous magnesium significantly reduced the incidence of moderate-to-severe catheter-related bladder discomfort immediately after surgery (22% in the magnesium group vs. 77% in the control group).

Patients receiving magnesium also reported higher satisfaction levels postoperatively, indicating that magnesium not only alleviates discomfort but also enhances the overall patient experience without increasing adverse effects.
