Testicular neovascularization by "omentotesticulopexy': a possible adjuvant in the surgical correction of high undescended testes.

The surgical repair of "very high" undescended testes may bring about testicular atrophy, as a result of impaired vascular supply, whether caused unintentionally by extensive dissection, or deliberately when the Fowler-Stephens operation is employed. In this experimental study, improvement of the vascular supply by means of "omentotesticulopexy" (an omental flap pexied to the rat testis) before or concomitant with spermatic vessel division (known as the Fowler-Stephens operation) was achieved and demonstrated by angiographic studies. The authors believe that the addition of "omentotesticulopexy" to the Fowler-Stephens operation will reduce the rate of testicular atrophy among patients with high undescended testes.
