This small volume is a syllabus intended for third year medical students and serves this purpose only. Essentially, it introduces urology on the physiologic and pathologic instead of the anatomic basis. Eight types of change are emphasized throughout as the basic elements of the mosaic of urologic diseases—obstruction, infection, lithiasis, neoplasm, congenital malformation, trauma, foreign body, and neurogenic changes. Each of these is considered with appropriate illustrations from specific diseases. The discussion is terse, concentrated, and to the point. The chapters on catheterization and history taking and physical examination are useful. There is a list of recommended reference books, including the standard American texts. It is to be regretted that the author did not expand this book into a more complete discussion of urologic mechanisms, suitable for the general physician.
