Being himself one of the founders of the modern doctrine of functional diagnostics of the kidneys - recalling his exceptional value of the study of renal function in experimental nephritis - Professor S., naturally, in his book, focuses on the importance for the doctor of studying the function of the diseased organ, without touching the pathological and anatomical side of the issue and deliberately not stopping on controversial theoretical problems. The purpose of the book is purely practical, to give a clear and concise statement of the current state of the teachings on renal diseases and to formulate precisely, concretely the necessary and at the same time only reliable therapeutic measures.
