[Status of penis sonography in andrology]

Good visualization of the anatomic structures of the penis can be achieved by application of high-resolution real-time sonography and a water path. Penis sonography is painless, free of risk and easy to perform. It is ideal for documentation and assessment of pathological alterations of the penis. 80 patients with penile deviation were examined sonographically. In cases of Peyronie's disease, the most frequent clinical picture, it is possible to achieve good localization and measurement of the fibrotic plaques in the area of the tunica albuginea. Calcifications can be clearly detected. In cases of penile deviation associated with the urethral manipulation syndrome, no fibroses are seen in the corpus spongiosum. In 3 patients with erectile impotence after priapism, sonography permitted precise determination of the extent of fibrosis formation in the corpora cavernosa.
