What this Trial Is About

Researchers are evaluating whether intravenous magnesium can help treat bladder spasms that occur after urologic surgery. This Phase 2 clinical trial compares magnesium infusion to a placebo in adults undergoing bladder invasive procedures, aiming to better understand its impact on post-operative bladder spasms. Participants will be randomly assigned to receive either an intravenous magnesium infusion or an equivalent volume of normal saline (placebo) during their urologic surgery. The magnesium dose includes a loading infusion of 50 mg/Kg followed by 15 mg/Kg per hour. The study is quadruple-masked to keep participants and researchers unaware of the assigned treatment during the surgery. During the study, researchers will monitor the incidence and severity of bladder spasms approximately 1 and 4 hours after surgery. They will also assess treatments used for spasms and patient satisfaction about 4 hours post-operation. The trial involves outpatient procedures and aims to complete by the end of 2026, with careful safety and effectiveness monitoring throughout.
