About this study

Official title: The Effectiveness of Early Sacral Nerve Stimulation in Improving Bladder- Related Complications and Quality of Life After Acute Traumatic Spinal Cord Injury

The purpose of this study is to see what effects sacral neuromodulation has on bladder function and quality of life in patients with acute spinal cord injury. Within 12-weeks of injury, participants will either receive an implanted nerve stimulator (like a pace-maker for the bladder) or standard care for neurogenic bladder. Patients will be assigned to one of these groups at random and followed for one year. The hypothesis is that early stimulation of the nerves will help prevent the development of neurogenic bladder.

Questions about this trial

What is this clinical trial studying?

A study testing PrimeAdvanced Surescan 97702 Neurostimulator - Medtronic (Minneapolis, MN) in people with Spinal Cord Injury, Acute and Neurogenic Bladder, run by University of Utah at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 10 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Cystometric Capacity (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
