[X-ray control of the kidneys and their development in the long-term period after surgical correction of hydronephrosis in children].
After surgical correction of hydronephrosis, the development of the kidneys was studied in 40 patients (44 hydronephroses) operated on at the age of 8 months to 12 years. Postoperative follow-ups lasted at least 10 and 25 years. X-ray planimetric studies made it possible to quantitatively characterize the growth of the kidney, the increase or decrease in its parenchymal area, the appearance or progression of prior nephrosclerosis. X-ray studies could yield an objective assessment of the trend in renal development. By supplementing the data of excretory urography, radiological techniques and ultrasonography provided additional data on the kidney and its parenchyma. Analysis of the results of the X-ray planimetric studies have indicated that 28 patients (32 kidneys) had a uniform increase in the areas of the kidney and its parenchyma by 50-100%; in 9 patients, the parenchyma increased by 2.5-4 times, the area of the kidney became only 50-100% larger. There was progression of nephrosclerosis with a 3-10% decrease in the area of parenchyma along with a 24-80% growth of the organ only in 3 cases after a quite satisfactory growth in the organ. These data show it necessary to perform long-term follow-ups of patients under the control of X-ray study as the most objective radiation diagnostic technique.
