Handbuch der Urologie.

Lichtenberg deals in an introductory chapter with the general diagnosis and symptomatology of urologic disorders. Though appreciating all the available technical methods, the author emphasizes the importance of the elicitation of a complete history and of persistent general observation of the patient. The roentgen diagnosis of the uropoietic tract and of the urinary bladder is also discussed. Special attention is paid to the technical details. In connection with this, the determination of the pictures developed is given and all sources of possible errors are pointed out. Instructive also is the chapter on congenital malformations as they appear in roentgenograms. The functional renal tests are discussed by Casper and Richter and the results are evaluated. Ringleb, who is known as an authority in cystoscopic construction deals with instrumental urologic technic with particular consideration of endoscopy and cystoscopy. A more extensive consideration of the most modern American instruments would have been desirable.
