US Imaging in Peyronie's Disease.

The aim of this study is to assess the role of ultrasound (US) in Peyronie's Disease (PD). PD is a psychologically and physically devastating disorder that manifests in middle-aged men. Fibrous inelastic plaques in the tunica albuginea, result in palpable penile scar in the flaccid condition and cause painful erections and penile deformity, including penile curvature, hinging, narrowing, and shortening of penis. Penile deformity is the most common (52%) first symptom of PD and is present in 94% of affected men. US is the primary imaging modality of choice due to its easy availability, low risk, and ability to image and quantify both calcified and soft tissue elements of PD. US provides identification of smaller and non-palpable lesions and shows the extent of fibrosis. Detection of calcifications within the plaque suggests stabilization of the disease and provides information useful to select patients for appropriate treatment.
