This big study looked at over two thousand five hundred young patients who had urine flowing backward into their kidneys. Doctors compared those taking daily antibiotics to others who did not take any medicine or took different types of treatments. The main goal was to see if the medicine could stop urinary infections from happening again.
The results showed that taking antibiotics every day did lower the chance of getting a new infection. Patients on the medicine had about twenty-one percent fewer infections than those who did not take them. This finding held true even when looking at studies that were done very carefully.
But there was a big worry about the medicine. Kids taking the daily antibiotics were much more likely to develop drug-resistant bacteria. This means the germs become stronger and harder to treat with standard antibiotics later on. The study did not find that the medicine caused new kidney scarring, but the resistance issue is a serious concern.
Doctors must weigh the good of stopping infections against the bad of creating stronger germs. Many of the studies used to make this conclusion had some flaws in how they were done. This mix of good and bad results means doctors need to talk with families about the best choice for each child.
