Scanning electron microscopy of the urinary tract.

Scanning electron microscopy of the urinary tract. A scanning electron microscopic investigation of the luminal surface of the entire urinary tract of the Wistar rat was performed. This report defines criteria for identifying different segments of normal urinary tract on the basis of scanning electron microscopic observations of the epithelial surface. The study was undertaken to provide a reference for future studies of changes in urinary tract morphology resulting from injury or disease.
