Urine infections/ hallucinations

My wife doesn't have hallucinations but has plenty of urine infections obviously your mum needs to drink lots of water. When my wife goes to the toilet she has a wee then waits a bit then has another.When she thinks there is an infection i take a sample to our GP then after treatment i take another to see if its gone.She has not got one at the moment.Her movement and fatigue is bad but if she has an infection its much worse.
