5bugles,
There is no medical evidence of which I am aware that indicates a growing dependency on intermittent catheterization. In fact, as I recently posted in another topic, my urologist has said that I now can stop self-catheterizing as my post-void residuals have dropped to healthy levels.

I attribute that largely to Kegel exercises (ask your doctor about them) and daily timed-voiding where I work to maintain control.
Don't worry about "over posting". We all had (and often continue to have) many questions. This is a good place to get answers, or at least recommendations.
Do search the old messages in the archives and the New Diaper Primer and my white paper "An Introduction to Adult Diapers, their Selection and Wear." in the Articles.
