title: [Duckett's procedure of one-stage urethroplasty for hypospadias].
abstract: OBJECTIVE
  To study the clinical effect of Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap in the treatment of hypospadias.
  
  
  METHODS
  We retrospectively studied 20 cases of hypospadias treated by Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap (Group A) from 2003 to 2007. The patients ranged in age from 2 to 22 years (mean 11.3 years). Another 30 hypospadias patients aged 7 to 34 (mean 16.1) years underwent urethroplasty with mucous membrane of the bladder (Group B) in the same period. Of the 50 cases, 13 were the penile type, 33 the penoscrotal type, 2 the scrotal type, and 2 the perineal type. Catheters were indwelled in Group A, but both cystostomy and catheter indwelling were used in Group B.
  
  
  RESULTS
  For Duckett's procedure, surgery succeeded in 17 cases (85%), urethra stenosis developed in 1 (5%) and urinary fistula in 2 (10%), which were successfully repaired 6 months after the operation. The mean operation frequency was 1.1 per patient. In Group B, the operation was accomplished in 2 stages and succeeded in 26 cases (86.7%), with postoperative development of urinary fistula in 3 (10%) and urethra stenosis in 1 (3.3%). The mean operation frequency was 2.1 per patient. The 2 cases of postoperative urethra stenosis were both cured by urethral sounding.
  
  
  CONCLUSIONS
  Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap is effective in hypospadias repair, with a success rate close to that of other types of operations and a low rate of postoperative complications. Compared with the use of mucous membrane of the bladder, it has the advantages of one-move accomplishment and gives a better penile appearance.
