Abstract：ObjectiveTo investigate the ultrasonographic characteristics of testicular torsion in neonates. MethodsThe clinical data of a patient admitted to the Urology Department of Chengdu Women′s and Children′s Central Hospital for testicular torsion on May 8, 2019 was analyzed retrospectively. The position, size, shape, echo, blood flow and other image data of testis examined by ultrasound were analyzed, and the relevant literatures were reviewed. ResultsAfter six hours of birth, the infant cried with no obvious inducement, of whom the right scrotum was swollen with tenderness, and the skin was cyan and purple. The tenderness was obvious of the upper part of scrotum, and the pain did not change obviously when lifting. The light transmission test showed that there was effusion in the scrotum. There was slight tenderness in the right groin spermatic cord area, and no obvious abnormality in the left scrotum. Ultrasound showed that the right testicular parenchyma was inhomogeneous, and there was no radiation echo, no obvious blood flow signal was detected in the parenchyma. The right epididymal head was thickened, and the echo was inhomogeneous, and there was no linear echo, and there was no echo in the right testicular sphingomyelin cavity. The left testicular parenchyma had uniform echo, no obvious abnormality in blood flow distribution, and there was no obvious abnormality in the left epididymis. On the right side, the spermatic cord was thickened, the echo was inhomogeneous, and there was punctate blood flow. Ultrasound suggested the possibility of torsion of right scrotum testis. ConclusionUltrasound examination can accurately diagnose testicular torsion of newborn, which is helpful to provide accurate basis for the treatment of children.
