Work up first
If you are prone to uti's, then you may need to have a good work up to rule out any anatomical problems that predispose you to having one.
If that's rule out and you are sexually active, make sure you void after sex
. Also, you want to keep yourself hydrated, so your urine
will be less concentrated and therefore will not be retained in the bladder
for very long. Using acid rich juices may help.
