Dorsal_Dartos_Flap_in_Snodgrass_Hypospadias_Repair_How_to_Use_it.pdf | 979.14 KB |
Purpose: To introduce new technique for covering neourethra with dorsal dartos subcutaneous tissue in Snodgrass hypospadias repair.
Material and Methods:
The study included 26 patients with primary hypospadias, aged 2–22
years (average 7.86), operated from June 2002 to August 2006. Of the
patients, 21 had distal, 3 midshaft and 2 penoscrotal hypospadias. The
standard technique of tubularized incised plate (TIP) with double-layer
covering of the neourethra by subcutaneous tissue was used in all cases
of reconstruction. The mean follow-up period was 4.5 months (range 3–12
months).
Results: Successful result of a
normal-looking penis without fistula was achieved in all patients. One
patient had meatal stenosis (3.84%) at the early postoperative period
which was corrected by urethral dilatation of the external meatus at an
interval of up to 2 months postoperatively.
Conclusion:
Our technique represents a reasonable option for utilizing dorsal
dartos subcutaneous tissue in TIP urethroplasty. The neourethra is
covered symmetrically with a double layer of well-vascularized tissue
and the penis is kept without rotation. Redundancy of the flap and its
excellent vascularization depend on the harvesting technique. Further
follow-up and a larger number of patients are needed before a final
conclusion can be made
