ABSTRACT

Objective To investigate the value of high frequency ultrasound combined with color Doppler flow imaging in diagnosis and classification of trauma of penis on the clinical treatment . Methods T he sonographic features of 48 cases with penile trauma were analyzed and compared with treatment outcomes . Results T he ultrasonic findings of penile trauma ranged from penis contusion to penis fracture . According to the sonographic features ,the trauma of penis was grouped as follow sType 1 ,penis bruise ( 7 cases) presented with images of continuous penis skin and tunica albuginea ,inhomogeneous echoes of subcutaneous tissue . Type 2 ,corpora cavernosa bruise ( 4 cases ) showed images of continuous tunica albuginea ,inhomogeneous internal echoes of corpora cavernosa without abnormal flow signal . T he corpora cavernosa swelling into honeycomb‐like ,anechoic area of cavernosa with high‐speed artery Doppler signals w hen accompanied by cavernous artery injury . Four cases were treated conservatively . Type 3 ,the skin and subcutaneous tissue contusion ( 6 cases) manifested images of incontinuous and inhomogeneous echoes of skin and subcutaneous tissue but homogeneous echoes of corpora cavernosa and tunica albuginea . Six cases of patients underwent debridement and sutured by local anesthesia . Type 4 ,rupture of tunica albuginea( 26 cases) revealed images of incontinuous and irregular local tunica albuginea ,a hematoma seen between the tunica albuginea and subcutaneous tissue . Type 5 , penile fracture ( 5 cases ) revealed mostly or fully disconnected skin and corpora cavernosa ,tearing of blood vessels . T he patients of type 4 and 5 were all treated surgically . Conclusions Color Doppler ultrasonography could provide accurate assessment and classification for trauma of penis ,w hich is helpful to offer a reliable basis for clinical treatment scheme .
