Introduction: To evaluate the imaging accuracy in the diagnosis and clinical management of penile injury.
Materials and methods: From January 2010 to January 2020, 20 men (median age 40.2 years) were admitted to our Emergency Department with the diagnosis of penile injury; the penile trauma was related to sexual intercourse in 16 cases, masturbation in 3 cases and injury caused by the partner in 1 case. All the patients underwent accurate medical history, clinical examinations and diagnostic imaging. Color Doppler ultrasound (CDU) evaluation was performed by Logiq E9 ecograph (General Electric; Milwaukee, WI) supplied with a linear probe small (7.5-10 MHz); magnetic resonance image (MRI) examination was performed within 3-24 hours from the trauma using a 1.5 Tesla scanner, (ACHIEVA 3T; Philips Healthcare Best, the Netherlands) performing pre-contrast and post-contrast multi-planar turbo spin-echo T1 and T2-weighted sequences.
Results: 15/20 (75%) men with high suspicion of the tunica albuginea rupture underwent surgical exploration; conversely, 5/20 (25%) patients underwent conservative management. CDU detected 11/15 (73%) fractures of the penis and in 8 of them the length of the rupture was underestimated (more than 5 millimeters). On the contrary, MRI diagnosed all the albuginea ruptures showed by surgical exploration, but underestimated the length of the lesions in 9/15 (60%) cases. The IIEF-5 score administered six months later penile trauma demonstrated a good performance in all the patients.
Conclusions: In our series, all the patients with a tunica albuginea rupture < 5 mm. diagnosed by MRI were submitted to conservative management with a complete functional restitutio ad integrum.
