Comparative study of dartos fascia and tunica vaginalis pedicle wrap for the tubularized incised plate in primary hypospadias repair

OBJECTIVES To report a prospective comparative study on using dartos fascia, i.e. subcutaneous tissue of penile skin and tunica vaginalis pedicled wrap (TVPW) from the parietal layer of the tunica vaginalis of the testis, for a one-stage tubularized incised-plate (TIP) repair for hypospadias. PATIENTS AND METHODS Forty-nine patients (mean age 4.6 years, range 1-22) with hypospadias of different types (varying from coronal to penoscrotal) were repaired in one of three hospitals over 3 years. All patients were repaired using the TIP technique, with dartos fascia wrap used in 20 and TVPW in 29, without using a loupe or microscope during surgery. Urinary diversion and splinting were provided by a urethral catheter. The operative duration for both groups was similar at approximate to 2 h. RESULTS In the dartos fascia group there were three (15%) fistulae, but there were none in the TVPW group. CONCLUSIONS Although the dissection for TVPW seems to be cumbersome theoretically, it is not difficult. The combination of TIP and TVPW in primary repair may be a good alternative to other techniques.
