INtravesical Antimicrobial Agents v STANDard Oral Antibiotics for the Treatment of Acute UTI in Women With rUTI


About this study

Women have problems with oral antibiotics, including vagina and bowel infections. Also, bacteria causing urinary infections are becoming more resistant to oral antibiotis.
