“…Table 1 indicates the sediment findings in 21 different normal individuals. With the exception of the red cell average, our results are closely comparable to those obtained by Addis in a much larger series (3). With the two counts on patient 7 excepted, our highest normal red cell excretion was two hundred thousand in 12 hours.…”

Most of the present knowledge concerning structural changes in the kidney is the result of postmortem studies. An indirect approach to the understanding of structural changes in the living human kidney has been made possible by the researches of Volhard and Fahr (1), resulting in their pathogenetic classification. They have shown that with a fair degree of accuracy it is possible to predicate the anatomic renal defect upon known functional derangements. Addis (2)

“…The number was smallest when failure of the congestive type had not occurred, somewhat greater when it had, though at the moment no signs were present, and greater stil when they were. Granular casts which Addis (2) did not find in the urines of normal individuals were found in approximately half the cases.…”

It is well known that casts, red blood cells and white blood cells may be present in the urinary sediment of patients suffering from heart failure. In the manner that specimens of urine are usually obtained it is not possible to gain an accurate notion of the numbers of cells which are present, since variations in salt concentration and reaction of the urine may result in partial or complete disappearance of the formed elements of the urine. Addis (1) recommended a procedure which has for its object the secretion by the kidneys of urine of such high specific gravity and acidity that the integrity of the formed elements of the urine is maintained. By this means the number of elements in urinary sediment formed in a 12-hour period may be estimated. Addis (2) found that the number of casts passed in a 12-hour period varied in normal individuals between 0 and 4,270, the average being 1,040; the number of red blood cells between 0 and 425,000, the average being 65,700; the number of white blood and epithelial cells between 32,400 and 1,835,000, the average being 322,500. The casts were hyallne; granular casts were not observed.The present study is concerned with the estimation of the number of formed elements in the urines of patients suffering from chronic heart disease, especially of the so-called arteriosclerotic type, more particularly with reference to the state of heart failure of the congestive type.The patients were at rest in bed and were in water equilibrium. Observations were made in patients suffering from the congestive type of heart failure, and again in the same patients after the signs and symptoms of heart failure had disappeared.

In the majority of cases, painless macroscopic hematuria is a typical initial symptom of bladder carcinoma. The time of occurrence (early and late symptom) neither correlates with tumor size and degree nor with infiltration depth. The respective testing method and threshold value exert a significant influence on frequency and constancy of a potential microscopic hematuria. Without sufficient standardization, however, it is understandable that even the existing guidelines for diagnosis of hematuria recommend different methods and threshold values. This paper provides an overview of the various testing methods and threshold values in microscopic hematuria, their influence on the diagnosis of bladder carcinoma as well as the possibility of differentiating the source of hematuria morphologically.
