You should be prepared to clearly describe when the problem began and how it has developed. You will also need to discuss pregnancies and deliveries, illnesses and injuries, medications, previous surgeries, and pertinent family histories.
It is important to be clear about your symptoms. Starting a diary helps keep track of fluid intake, how many times and how much (a little or a lot) you urinate, and how often you've experienced leakage and/or felt a sudden need to urinate.
Keeping track of this information for one full week will give the urologist important information about your condition.
Many simple test and procedures can determine what kind of incontinence you have, and most of them can be performed right in the doctor's office.
Though medical histories and physical exams are the primary diagnostic tools, new tests make it easier than ever to diagnose incontinence and accurately identify its causes.
