With increasing emphasis on the early diagnosis and management of urologic tumours, it is imperative that the practising urologist comprehend the relevance of the morphology for the clinical diagnostic and therapy. Moreover, the clinician should be fully informed of the importance of modern morphological methods for the diagnosis and management of urological tumours. Not only is this highly illustrated text a necessary adjunct in the attending urologist's armamentarium, it will also satisfy the needs of residents in pathology or even of pathologists, who are not daily faced with urological tumours. The structure of the chapters follows a uniform schema: short introduction with the definition of the tumour/ tumours, clinical history epidemiology, aetiology, gross morphology, microscopy, tumour genetics, importance of ancillary methods for the diagnosis, differential diagnosis, principles of grading and staging, morphological prognostic factors, and clinical course. The tables showcase the latest WHO histological classification of the tumours of the single organs, the integral (or complete) form of the latest TNM staging version, and the principles of the international accepted grading systems (kidney, bladder, prostate, penis ). A short chapter is devoted to handling procedures for surgical specimens and biopsies by clinicians.
