Objective:
To investigate the application of tunica dartos flap coverage to the prevention of urinary fistula in tubularized incised plate (TIP) urethroplasty.
Methods:
This study included 140 cases of hypospadias following TIP urethroplasty, aged 1.9-22 (mean 5.6) years. Of the total number, 85 cases of the distal type were treated by coverage of the neourethra with the longitudinal ventrolateral pedicled-dartos penile skin flap, while the other 55 cases of the proximal type with the pedicled-dartos flap of arteriae scrotales anteriories.
Results:
Urethrocutaneous fistula occurred in 12 of the patients, including 7 cases of distal and 6 cases of proximal hypospadias.
Conclusion:
For distal hypospadias, the longitudinal ventrolateral pedicled-dartos penile skin flap can be used, while for proximal urethroplasty, the pedicled-dartos flap of arteriae scrotales anteriories can be applied in coverage of the neourethra, which can effectively reduce the incidence of fistula.
