Abstract Introduction The presence and extent of penile calcifications is an important factor in disease management of Peyronie’s Disease (PD). Calcified plaques may necessitate plaque excision and grafting (E&G) in addition to other therapies or surgeries. PD pathology such as corporal septal involvement, multifocal calcifications, and circumferential corporal calcification can be difficult to assess on color doppler ultrasound (CDDU) due to device limitations. Computed tomography (CT) can be utilized for further characterization of PD. Objective The objective of our study was to review patients who underwent CT imaging for characterization of their Peyronie's Disease. Methods Twenty-three patients with a diagnosis of PD were retrospectively evaluated between 2017 and 2021. Patients underwent CDDU examination with artificial erection and were evaluated based on erectile function, plaque dimension, hourglass deformity, plaque septal involvement, and suspected calcification status. Patients with CDDU examination suggestive of calcification or significant complexity underwent non-contrast CT scan for 3-dimensional evaluation of the plaque prior to surgical discussion. CT complexity was defined as concern for multifocal calcified plaques (>2), partial/complete circumferential corpus cavernosum involvement, or septal involvement. Results All 23 patients had concerning findings on initial examination for calcified plaque which led to their CT evaluation; 9 of 23 (39.1%) patients had exam findings with hourglass deformity. On CT evaluation, calcification was confirmed in 22 of 23 patients (95.7%). Plaque dimensions on CT scan ranged from 0.4 x 0.2 x 0.5 cm to 4.0 x 2.0 x1.7 cm. Many of these measurements were approximations due to circumferential calcified plaque. A classic “gull-wing” appearance was noted in 6 of 23 (26%) patients; 12 of 23 (52.2%) of patients had septal involvement on CT; 8 of 23 patients (34.8%) had significant multifocal disease; 8 of 23 patients (34.8%) decided to proceed with surgical correction via E&G (n = 3), IPP with E&G (n =1), or via IPP with manual remodeling via Wilson technique (n = 4). Conclusions Non-contrast penile CT scan identifies calcification well in patients with Peyronie's Disease. CT allows for increased accuracy of surgical planning especially when evaluating for multifocal disease, circumferential plaque and/or septal involvement. These elements are critical for for providing accurate surgical recommendations and preoperative discussions. Disclosure No
