The role of magnetic resonance imaging for the diagnosis of penile fracture in real life emergency settings – comparative analysis with intraoperative findings

AbstractPurpose:To evaluate the role of magnetic resonance imaging (MRI) of the penis in the diagnosis of penile fracture and/or concomitant urethral lesion in real-life emergency settings in comparison with intraoperative findings.Materials and methods:Forty-three patients presented with suspicion of penile fracture between January 2006 and December 2016. MRI was performed in 28 patients prior to surgical treatment in emergency settings. Surgery was performed in all patients through subcoronal circumferential degloving approach. Sensitivity, specificity, positive and negative predictive value (PPV/NPV), as well as the likelihood ratio for positive and negative results (LR+/LR-) were calculated for the agreement between MRI and intraoperative findings. Confidence intervals (CI) were set at 95%.Results:Intraoperatively, penile fracture was confirmed in 19/28 (67.9%) patients, while concomitant urethral lesion was observed in 5/28 patients (17.9%). MRI findings were highly associated with intraoperative fin...
