title: Our 21-year experience with the Thiersch-Duplay technique following surgical correction of penoscrotal transposition.
abstract: OBJECTIVE
  To assess surgical techniques applied after surgical correction of penoscrotal transposition and their complications.
  
  
  METHODS
  The medical records of 64 patients with a mean age of 4.1 years (range 1-24) who underwent surgical correction for penoscrotal transposition and subsequent Thiersch-Duplay urethroplasty in the last 21 years were evaluated retrospectively.
  
  
  RESULTS
  All cases underwent Thiersch-Duplay urethroplasty following reconstruction of penoscrotal transposition after a minimum interval of 6 months. Following Thiersch urethroplasty, 41 (64%) cases with successful outcomes had glandular meatuses. Of the remaining 23 (36%) patients 15, 7 and 1 patients underwent second operations for urethrocutaneous fistulas, meatal regressions and urethral diverticulum, respectively. Eleven of 15 patients underwent primary fistula repair and 4 patients, turnover fistula repair. These patients had glandular meatuses following fistula repair. Seven cases with meatal regression and breakdown of the neourethra were reoperated on by using double-face urethroplasty, onlay island flap urethroplasty and free-tube urethroplasty techniques. Finally, all patients had glandular meatuses. One patient with urethral diverticulum underwent successful diverticulum excision and meatoplasty.
  
  
  CONCLUSIONS
  Thierch urethroplasty is the most commonly performed technique after surgical correction of penoscrotal transposition; however, additional procedures are needed for the management of its complications.
