In the erect penis, trauma results from stretching and narrowing of the tunica albuginea, which can undergo segmental rupture of one or both of the corpora cavernosa, constituting a penile fracture.In the ultrasound examination, a lesion of the tunica albuginea presents as an interruption in (loss of continuity of) the echoic line representing it (Figure 4). Small, moderate, or broad hematomas demonstrate the extent of that discontinuity. Intracavernous hematomas, sometimes without the presence of a tunica albuginea fracture, can be observed when there is a lesion of the smooth muscle of the trabeculae surrounding the sinusoid spaces or the subtunical venular plexus. In 10-15% of penile traumas, there can be an accompanying urethral lesion. When blood is observed in the urethral meatus, contrast-enhanced evaluation of the urethra is necessary. In cases in which the ultrasound findings are inconclusive, the use of magnetic resonance imaging can facilitate the diagnosis and is recommended by various authors. Treatment
Penile fracture is a medical emergency, and emergency surgical repair is the usual treatment. Delay in seeking treatment increases the complication rate. Non-surgical approaches result in 10–50% complication rates including erectile dysfunction, permanent penile curvature, damage to the urethra and pain during sexual intercourse, while operatively treated patients experience an 11% complication rate.In some cases, retrograde urethrogram may be performed to rule out concurrent urethral injury. Legal issues
In the United States, the case of Doe v. Moe, 63 Mass. App. Ct. 516, 827 N.E.2d 240 (2005), tested liability for a penile fracture injury caused during sexual intercourse.
The court declined to find duty as between two consensual adults. The plaintiff in this case, a man who suffered a fractured penis, complained that the defendant, his ex-girlfriend, had caused his injury while she was on top of him during sexual intercourse. The court ruled in her favor, determining that her conduct was neither legally wanton nor reckless. References
