Abstract

Objective To determine the role of penile Doppler ultrasound (PDU) compared with magnetic resonance imaging (MRI) in preoperative diagnostic evaluation of patients with penile squamous cell carcinoma. Materials and Methods A prospective analysis on patients presenting with clinical diagnosis of penile squamous cell carcinoma from 6 different European hospitals between 2012 and 2014 was carried out. Each patient who had planned an organ sparing approach underwent an MRI and PDU both with an artificial erection with prostaglandin E 1. Age, evidence of MRI or PDU corpora cavernosa infiltration, frozen section examination report, definitive pathological report, and surgical approach used per patient were recorded. Accuracy, precision, negative predictive value, sensitivity, and specificity were calculated. Outcomes were statistically evaluated. Results Two hundred patients were enrolled in the study. The mean age of the patients was 67.35 ± 15.45 (range 51-82). All of the patients were treated surgically. Of the 200 patients, 135 (67.5%) underwent a corpora sparing approach, whereas 65 had a partial penectomy because of the frozen section outcome. About corpora cavernosa infiltration, the definitive outcome confirmed the frozen section examination. PDU vs MRI accuracy was 96.5% vs 90.5%; precision was 92.6% vs 96%; sensitivity was 96.9% vs 73.8%, specificity was 96.2% vs 98.5%. Despite sensitivity (P
