Clinical experiences with different one-staged surgical methods for primary hypospadias cases.

The success of various types of operations for primary hypospadias was assessed taking the location of meatus and the degree of chordee as the basis. Totally 258 patients with primary hypospadias were operated: 94 by meatal and urethral advencement, 110 by perimeatal flap and tube repair and 54 by preputial flap. The rates of success in cases with meatal advencement, perimeatal flap and preputial flap were found as 88%, 81% and 66% respectively. The success of treatment in hypospadias cases is closely related to the age of the patient, the experience of the surgeon and the choice of an appropriate method. However, the presence of chordee and the proximally located meatus are among the leading factors that influence the rate of success.
