Ten cases of multicystic kidney in newborn infants are described herein. The diagnostic value of ultrasound during the prenatal period and postnatal follow-up is highlighted. The therapeutic approach in this condition is discussed.
An intense oxalo-calcium nephrocalcinosis can be produced in rats, by the experimental use of substances such as glyoxylic acid and ethylene-glycol which can be transformed into oxalic acid within the organism. So can it be possible to make the crystallographic study of the crystal precipitations induced after administering those substances. For that purpose we have used a total number of 24 rats to which the above mentioned substances were administered, at different doses and by different methods. Thus, an intense parenchymatous crystalline precipitation was obtained, which allowed us to study the structure of those crystals by means of C. Zeiss photomicroscope. The results obtained in the different groups studied were similar. A much higher presence of crystals of monohydrate calcium oxalate was observed, although crystals of dihydrate were also found, although some of them under clear process of transformation into monohydrate form.
In reviewing our experience in the field of bladder ultrasonography, we conclude that this method is seldom used because its value has not been disseminated widely. Such a method is especially valuable in the investigation of infiltrative bladder tumors and the calculation of bladder volume. We herein report the results obtained in 100 patients whose bladder content has been calculated with the formula 12.56 times radius times height. We also outline the advantages of ultrasound over catheterization.
We analyzed 70 prostatic calculi using crystallographic methods and determined the individual composition of the layers, structures and ultrastructures, thus, obtaining a more precise classification of these calculi.
