It depends on what caused the infection.
I had a kidney infection caused by E-coli in 1995. have never had a recurrence since (thank goodness)
Take cranberry supplements. Get the kind that say "take 1 per day" and take at least two. They've been proven to prevent urinary tract infections.
yes its very common once you have infection ..more may happen along the way always be checked nothing more than urine test or blood tests..
