[Koyanagi technique for repairing proximal hypospadias with penoscrotal transposition].

Abstract

OBJECTIVE:

To investigate the application of Koyanagi technique for repairing proximal hypospadias with penoscrotal transposition.

METHODS:

Koyanagi procedure was used for repairing proximal hypospadias with penoscrotal transposition in 26 boys (mean age 4.2 years) between July 2005 and June 2010.

RESULTS:

Primary healing was achieved in 22 cases. Three patients suffered from urinary fistula and the external urethral orifice in one patient was retracted to penis coronary sulcus, who were re-operated successfully. Two cases showed slight penile ventral curvature. Slight stricture of the urethral external orifice was noted in one case, which relieved after one to two times of urethral sounding every week for eight months. 20 patients were followed up for 6-36 months (mean 10.5 months) with good cosmetic result and normal urethra function. The penoscrotal transposition was also corrected.

CONCLUSIONS:

The original Koyanagi procedure might be one of the simple and effective method for repairing proximal hypospadias with penoscrotal transposition.
