[Application of tunica dartos flap coverage to tubularized incised plate urethroplasty].
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.


CONCLUSIONS
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.
