A penile fracture is defined as a tear of the tunica albuginea, surrounding the corpus cavernosa. It occurs when the erect penis is subjected to an abnormal ‘bending’ force, inducing an acute increase in intracavernosal pressures, exceeding the tensile strength of the tunica albuginea, which is approximately 1500 mm Hg, resulting in a tear, or so called ‘fracture.1 2

Up to 88.5% of penile fractures occur during sexual intercourse, with a 20-year retrospective study concluding ‘doggy style’ and ‘man on top’ as the two main etiological positions.3 4 Other lesser reported causes include masturbation, sleeping prone and ‘taqaandan’ (the practice of forcible detumescence performed primarily in Middle Eastern countries).5

This injury is most prevalent among men in their 40s, whom classically report a ‘popping’ sensation and immediate detumescence, following blunt trauma. On examination, the penis will be grossly swollen and ecchymotic (the so-called ‘eggplant’ sign) with a palpable ‘rolling’ sign. In up to 71% of cases, it is the right corpora which fractures, causing the penis to bend to the left.6 7

The British Association of Urological Surgeons recommend operative intervention within 24 hours, to reduce the risk of long-term complications including erectile dysfunction, excessive penile curvature or urethral stenosis.8 A penile MRI is not essential in confirming the diagnosis (especially if it is likely to delay operative intervention), however there is growing evidence supporting its role, particularly if there is concern regarding urethral involvement.9

In July 2020, a PubMed literature review confirmed that all documented cases in the English language, report a ‘transverse’ fracture of the tunica albuginea.1 3 6 10–12 In turn, we present the first documented case of a vertical penile fracture, confirmed on MRI, sustained by a 40-year-old man during sexual intercourse.

The patient reported that his penis buckled against his partner’s perineum. Interestingly, he described a gradual detumescence, with moderate swelling but no ‘popping’ sensation. Moreover, there was no palpable ‘rolling’ sign on examination. Given the presentation, a penile MRI was deemed appropriate in order to exclude a ruptured dorsal vessel and/or suspensory ligament.

The MRI confirmed a vertical disruption of the tunica albuginea at the ventral aspect of the right corpus cavernosum, along the medial third of the penile shaft (see figures 1 and 2). Guided by the MRI, the surgeon was able to target his exploration, confirming that indeed there was a 3 cm vertical tear. Unfortunately, due to COVID-19 restrictions, medical photography was prohibited.

Based on our literature review of the studies which specifically documented the fracture pattern, all were noted as being transverse, meaning that all other findings were based on transverse fractures and not vertical. Not only does this highlight the rarity of this case, but it also raises the question: Does a vertical penile fracture pattern alter either the presentation or long-term outcomes following operative repair?

Of course, more work is required to answer this question, however based on this case, it would appear that a vertical fracture is not associated with the classical features of a penile fracture, namely immediate detumescence, a ‘popping' sensation, gross ecchymosis and a palpable rolling defect. In terms of long-term outcomes, we will compare this patient’s recovery to that of the literature. Reassuringly however, this patient was able to resume sexual activity within 6 months of the injury, achieving erections of the same quality to those prior to the injury, denying any penile curvature or significant palpable scarring.

Learning points

  • A penile fracture is a urological emergency requiring operative intervention within the first 24 hours of injury.

  • A ‘popping’ sensation followed by immediate detumescence, with a palpable ‘rolling’ sign are classical presenting features of a penile fracture.

  • As the first documented example of a vertical penile fracture, this case raises the question: Does a vertical penile fracture pattern alter either the presentation or long-term outcomes following operative repair?
