ClinConnect Summary

This clinical trial is studying a new treatment method called ultrasound-guided urethral balloon dilation to see if it can help improve urination in patients who have urinary retention after a spinal cord injury. Urinary retention means that a person has difficulty emptying their bladder, which can lead to uncomfortable symptoms and affect their quality of life. The trial will compare two groups: one group will receive the new treatment along with standard rehabilitation therapies, while the other group will only receive standard therapies.

To be eligible for this trial, participants should be between 18 and 80 years old, have a confirmed spinal cord injury, and have experienced urinary retention after their injury. They must also be able to urinate on their own before their injury and have certain medical conditions ruled out. Participants will keep a daily diary to track their urination patterns and will have their bladder's urine volume checked before and after the treatment. This trial is currently looking for volunteers, and it's a great opportunity for those who want to explore new ways to manage their urinary issues after a spinal cord injury.
