This new textbook on urologic diagnosis presents knowledge and technical data necessary in establishing a urologic diagnosis. The authors discuss shortly and clearly the embryology, anatomy and physiology of the genito-urinary tract, then the examination of the patient, his urogenital secretions and excretions, and the instrumental exploration. They give considerable space to urethroscopy, cystoscopy, transvesical manipulations, and the determination of renal function. Urography, both retrograde and intravenous, is given especial attention. The text is clearly written, the numerous illustrations are excellent, and the editing is good. This work merits particular notice among those interested in urology.
