Concerned extremely, Michele  <response>: Hi Michele, some females can be prone to repeated UTI episodes even without any obvious underlying cause. However, if episodes are frequent or the infection involves kidneys, a thorough evaluation for a cause is needed. Your BP and kidney function creatinine also needs to be checked. You will also need long term antibiotic prophylaxis course of low dose antibiotic tabs for 6 months or more to prevent repeated infections. Cranberry extracts are now available in tablet form, these decrease chances of repeated infection. Consult a urologist or nephrologist. Good luck.
