Introduction Detecting renal scar is important in pediatric patients with vesicoureteral reflux (VUR) for deciding on treatment option. The aim of this study is to detect whether freehand elastosonography technique could be an alternative to dimercaptosuccinic acid (DMSA) scan in determining renal scar formation. Materials and Methods Between November 2015 and April 2016, 25 VUR patients, age ranging from 3 to 17 years admitted to our clinic, had urinary ultrasound and elastosonography, and data of approximately 147 renal region were recorded. Data were upper, middle, and lower pole renal parenchymal thickness and echogenicities obtained by ultrasound and these poles strain target (ST), strain reference (SR), and strain index (SI) values obtained by freehand elastosonography. DMSA scan data (differential function and upper, middle, and lower pole parenchymal scar formation) were recorded. Results Scar formation and more than 10% reduction in differential function in renal scan were statistically higher in renal regions in which parenchymal thinning and echogenicity increase was detected by ultrasound. There was no elastosonographic data difference between renal units with and without differential function decrease. Also, there was no elastosonographic data difference between renal units with and without scar formation. Conclusion In this study, we could not find any significant difference in term of tissue tension values (ST and SI) measured by freehand elastosonography between renal units with and without scar formation in renal scan.

Chronic pyelonephritis is one of the most common diseases of the kidney and accounts for a sizeable number of cases of renal insufficiency in man, however its pathogenesis requires further elucidation. Transmission electron microscopy may serve as a uniquely effective means of observing details of the nature of this disease. The present paper describes preliminary results of an ultrastructural study of chronic pyelonephritis in Macaca arctoides (stumptail monkey).The infection was induced in these experiments in a retrograde fashion by means of a unilateral catheterization of the left ureter whereby an innoculum of 10 cc of broth containing approximately 2 billion E. coli per cc and radio-opaque dye were injected under pressure (mimicing vesico-ureteric reflux).
