Abstract
Pregnancy induces a variety of physiologic changes in the urinary tract. When such changes become accentuated the physiologic becomes the pathologic and symptoms arise, at times of significance enough to threaten the well being of mother and/or fetus. This article intends to describe the basis for urinary physiology and its pathologic counterparts during pregnancy. Such a background may then facilitate a rational management protocol for various urologic problems in the gravid state.
