Objective To study the appearance of the normal male obturator internus using transrectal ultrasound compared with anatomy examinations to advance the knowledge of the male android pelvis muscle and to provide a new imaging method to observe the normal male obturator internus.Methods Ten formalin fixed cadavers were dissected to examine the appearances and structures of the obturator internus and its relationship with the peripheral organs.The obturator internus were also observed in a fresh male cadaver using transrectal ultrasound.In a fresh male cadaver,the obturator internus were located by transrectal sonography,the muscle was confirmed by anatomy,and the thickness was measured.Results The ultrasonographic observations of the location of the obturator internus were confirmed by anatomy for the fresh cadaver.The visible fusiform sonogram was observed in the sonographic image.The right and left obturator internus thickness measurements were 13.6 and 13.7 mm by sonographic image,respectively,while in formalin-fixed fresh cadaver the measurements were 13.16 and 13.17 mm,respectively.Conclusion Using transrectal ultrasound to recognize and observe the obturator internus is a new imaging method.
