Classification of congenital and acquired penile deviation.

In addition to sonography and the classical diagnostic tools, a new method for the accurate classification of congenital and acquired penile deviation is made possible by using autophotography, 'five-line system' to determine the angle of deviation, and the table for 'classification of Peyronie's disease'. it is suggested that the wide use of this new method of documentation would lead to a better comparison of the results and understanding of the disease.
