The Fisher Technique for Correction of Penile Torsion in Children: Who Are the Candidates?

Abstract

To report our experience in the treatment of penile torsion with a special reference to the Fisher technique. We reviewed 30 cases of congenital penile torsion treated from 2009 to 2015 in a single center. Sixteen patients presented a moderate rotation of 45°-90° and 14 had a severe rotation with an angle greater than 90°. Chordee was present in 17 cases and distal glanular hypospadias in 15 cases. Median age at surgery was 10 months. In 14 cases, degloving along with skin realignment, alone, allowed correction of the torsion. In 16 cases, the Dartos flap (Fisher technique) was used. Out of the 30 patients, 29 had a good result, with a complete correction of the torsion. Only 1 patient had a residual torsion of 30°. Complications were minor and consisted of skin excess in 11 patients; 1 single case needed to be reoperated for that skin complication. The need for the Dartos flap procedure was significantly correlated to the degree of torsion (P = .001): it was used in 4 out of 16 patients (25%) with a torsion of less than 90°, and in 12 out of 14 patients (86%) with a torsion of 90° or more. Most of penile rotations less than 90° can be corrected by skin degloving and realignment. The Fisher technique is a simple and safe procedure for correction of persistent rotation after skin degloving; such cases have usually a penile rotation greater than 90°.
