A new machine technique in cord: Elastosonography

Abstract

B mode US imaging with elastosonography tecnology was performed on the cords by 4-13 MHz linear probe (Esaote, MyLab60 with Elaxto application). The elastosonography technic demonstrated a colour map over B mode image. Different colours extended from green (soft) to ruddy (hard) to illustrate tissue feature after compression-decompression periods. In kids, spermatic cord with testicular torsion is among the main significant events. Differentiation from other acute scrotal events is confusing in diagnosis and therapy. The point of experimental research is to determine the viability of elastosonography, which investigates stiffness as a target strategy in determination and intervention of spermatic cord torsion. 16 male rabbits of a similar weight and age were chosen. They were separated into 2 groups including 8 rabbits. In Group 1, right testis was constant; in Group 2, the same testis experienced 720° curve a clockwise way and stabilized. After 1-2 hours of ischemic period, elastosonography estimations were applied. Nonetheless, the left spermatic cord was estimated again at 24 hours to notice the possible progressions; because ischemia may also have an effect to the left spermatic cord. B mode US and elastosonography procedures were applied with a linear probe. Statistically increment was recognized in elastosonography estimations of right spermatic cord at 1-2-24 hours (p<0.05). There were no significant changes between the groups of left spermatic cord at 1-2 hours. Elastosonography values were significant in left spermatic cord at 24 hours (p<0.05). The elastosonography estimations of the spermatic cord torsion appeared evidently with the expansion in span of ischemia. It was seen that the elastosonography strategy may have a part with other indicative procedures in diagnosis of cord torsion.
