(A) The right testis was located in the subcutaneous fat layer and the bladder was overfilled. (B) Obvious swelling of scrotum, and no testicles were found in the right scrotum. (C) Comminuted fracture of pelvis. (D) The catheter balloon was outside the bladder.

After the injury, the patient went through acute urinary retention (Figure 1A). Computed tomography (CT) scan showed edematous lower limbs and perineum (Figure 1B), purpura, and obvious local tenderness. CT scan showed a comminuted fracture of the pelvis and sacrum (Figure 1C). The catheter balloon was not located in the bladder (Figure 1D).
(A) Transpelvic ultrasound examination revealed membranous urethral rupture. (B) Color Doppler US image of the inguinal mass revealed a intact shape of testicle with blood supply. (C) Pelvic CT showed the swollen scrotum and the empty right scrotum. (D) Re-examination of pelvic CT after surgery.

Pelvic floor ultrasonography (Figure 2A) was done during transurethral injection of normal saline, and presented that the penile part of the urethra was naturally dilated and the mucosa was smooth. Color Doppler ultrasound image of right inguinal mass (Figure 2B) presented a moderate echo with a size of 4.1*1.2 cm in the subcutaneous fat layer, with clear boundary, intact shape, and blood flow signals, which was consistent with a normal testicular echo. Reexamination of the pelvic CT showed that the right scrotum was empty and asymmetrical to the left (Figure 2C). CT re-examination (Figure 2D) confirmed the testicles remained in place.
