Medical scientists don't seem to have many theories about what causes urinary infections in women. They think that the anatomy of women makes it more likely that they will get bacteria into the urinary system.
But the idea that the urinary opening might be constricted and can cause urinary infections is new to me. The remedy sounds fairly simple - dilating the opening in an outpatient setting.
I wonder how many women, who have frequent urinary infections, have looked into the dilation of the urinary opening as a way to minimize infections.
