[Application of tubularized incised plate in one-stage urethroplasty for hypospadia accompanied with anatomic kak-factors].

OBJECTIVE

To investigate the application of tubularized incised plate (TIP) in urethroplasty for hypospadia accompanied with anatomic kak-factors.

METHODS

We retrospectively studied 191 cases of hypospadia treated by one-stage TIP urethroplasty. Taking the position of the urinary meatus, the development of the glans penis and urethral plate, and the degree of penile ventral curvature as anatomic kak-factors inducing postoperative complications and affecting the appearance, we conducted correlation analyses on the clinical effects of the procedure using SPSS 10.0 statistics.

RESULTS

Postoperative complications were closely correlated with the position of the urinary meatus, the nearer its position to the coronary sulcus, the higher the incidence of complications (chi2 = 24.291, P < 0.01). And so were they with the development of the glans penis and urethral plate and the degree of penile ventral curvature. The incidence of postoperative complications was significantly higher in the hypospadia patients with small glans, maldeveloped urethral plate and severe penile ventral curvature than in those with straight penis and well-developed glans and urethral plate (chi2 = 25.419, P < 0.01).

CONCLUSION

Tubularized incised plate urethroplasty for hyper-spadias should be chosen according to the position of the meatus, the development of urethral mucous membrane, the degree of ventral curvature and surgery experience in order to achieve a high cure rate and good cosmetic effect.
