Summary

This study tests whether sildenafil (the drug in Revatio, similar to Viagra) can reduce urine leakage in people with spinal cord injuries. Twenty-four adults who have at least three leaks per week will take either sildenafil or a placebo for four weeks. Researchers will track how many leaks they have each day using a bladder diary.
