Excellent illustrations and the latest technology from the clinic, practice and laboratory are compiled for both the practicing urologist and the researching cytopathologist in the book "Urinary Cytology." The completely revised and up-dated text in the new second edition reflects the first common effort of urologists, pathologists and cytopathologists to find a unified concept: from conventional cytology to electron microscopy toflow cytometry. The authors' main emphasis is on conveying practical techniques for the collection, concentration, fixation, staining and analysis of cellular material. They clearly discuss the circumstances under which new techniques are advisable and the relevance of these techniques when difficult questions of detail arise. At the same time, basic scientific principles arepresented in comprehensible form. The atlas section gives examples of urologic cytology, compares pathological with normal results, discusses the problems in differential diagnosis and points the way to solutions.
