Fluoroscopy Radiation Reduction During Sacral Neuromodulation Lead Placement

This study is looking at whether ultrasound guidance during sacral neuromodulation lead placement can reduce the amount of X-ray radiation patients are exposed to. Sacral neuromodulation is a procedure where a small device is implanted near the tailbone to send electrical signals to the bladder nerves, treating overactive bladder symptoms like urgency, frequency, and leakage. Traditionally this procedure uses a lot of fluoroscopy (real-time X-ray). Researchers want to see if ultrasound can achieve the same accuracy with less radiation. You may be eligible if: - You are between 18 and 89 years old - You are having a sacral neuromodulation lead implant for overactive bladder (urgency, frequency, nocturia, with or without incontinence) You may NOT be eligible if: - You have a neurogenic bladder (nerve-caused bladder dysfunction) - Your BMI is above 40 - You have peripheral neuropathy Talk to your doctor to see if this trial is right for you.
