Dr. Lucke states, in a short introduction, that this small book was published at the suggestion of the editor of the Deutsche medizinische Wochenschrift, in which his work first appeared. It was presented primarily for the benefit of the general practitioner as a short review. He divides the work into two parts: The bilateral hematogenous renal diseases (medical kidneys) and the so-called surgical diseases of the kidneys. It is a comprehensive but short review, well done, and eliminating all unnecessary and irrelevant matters. First he discusses the normal kidney, then the symptoms and signs of renal disease, especially the pathologic urinary conditions, hypertension, function and edema. Uremia, anuria, the nephritides, nephrosclerosis and congested kidney are described. The surgical disorders of the kidney are nicely and shortly portrayed, especially tumors, tuberculosis, calculus and infections. This monographic review can be recommended to student and practitioner alike, and the trained urologist as well
