Congenital curvature of the penis without hypospadias.

A series of 18 cases of congenital curvature of the penis without hypospadias is reviewed. Two types of curvature are differentiated. One type (12 cases) without any other anomaly of the penis is treated by a single-stage operation without involving the urethra. In the second type (6 cases), the curvature is associated with hypoplasia of the urethra on a more or less long portion, and it has to be treated as a concealed hypospadias.
