'Sterile' Urine May Be a Myth

Image
Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.

"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These findings challenge this notion."

Brubaker's team analyzed urine samples from 90 women. It found bacteria both in the urine of healthy women as well as the urine of women with overactive bladder. However, the germs were different between the two groups, the researchers said.

"The presence of certain bacteria in women with overactive bladder may contribute to overactive bladder symptoms," lead investigator Evann Hilt, a second-year master's student, theorized in the news release. But only more study can confirm whether those bacterial differences are "clinically relevant for the millions of women with overactive bladder," Hilt added.
