Hello and welcome to HCM.
Thank you for your query.
Please understand that, for all recurrent UTI's there is almost always an underlying cause that is causing the UTI to either return or not get completely treated. The possible causes for this could be:
-Kidney or bladder infections
-Infections of surrounding structures
-Compression/obstruction of any part of the renal system that is resulting in stagnant urine, resulting in a UTI
and many other..
Please discuss the possibilities with your doctor. In such cases, UTI is not the condition that requires treatment. Treating the primary cause results in complete relief from the UTI's as well.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
