Modified pudendal-thigh flap for correction of penoscrotal transposition
1Department of Urology, Mayo Clinic and Mayo Foundation, Rochester, Minnesota 55905, USA.
Objectives:
In patients with penoscrotal transposition, an occasional postoperative problem has been a deficiency of skin on the proximal penile shaft that results in penoscrotal fusion and tethering.
Methods:
We describe a new operation using a modified neurovascular pudendal-thigh flap for correction of incomplete penoscrotal transposition.
Results:
This procedure has been used in 6 children, and an excellent cosmetic and functional result has been achieved in each patient.
Conclusions:
The flaps provide a reliable blood supply, maintain normal innervation, and correct the problem of postoperative penoscrotal fusion and tethering. This technique preserves sufficient penile skin for a tension-free second-stage urethroplasty.
