Background In hypospadias repairs, there is some evidence to suggest that a \'waterproofing\' layer can be helpful in reducing the risk of urethrocutaneous fistula formation. The most likely role of this layer is to prevent the creation of overlapping suture lines. Many hypospadias surgeons use a dartos fascia interposition flap for this purpose. However, raising a dartos fascia flap adds time to the procedure, can result in devascularization of the overlying skin, and can create unsightly torsion of the penis, which may be hard to correct. To avoid these problems, the senior author has started to use dCELL (decellularized human dermis) as an alternative to dartos fascia to separate the suture lines. Methods Between March and July 2018, a pilot study was performed in 8 patients undergoing closure of a urethrocutaneous fistula or glans dehiscence combined with dCELL. Data on infections, wound breakdown, length of stay and catheterization, surgical time, and hospital stay were collected. Results All patients had a successful reconstruction. One patient developed a urinary tract infection, possibly related to prolonged catheterization following his repair. Conclusion Our results suggest that dCELL may be useful in the repair of urethrocutaneous fistulas and glans dehiscence after hypospadias surgery.
