Surgical correction of abdominal testes after Fowler-Stephens using the neodymium: YAG laser for preliminary vessel dissection.

Two boys with high undescended testes were submitted to laparoscopic laser transsection of the internal spermatic vessels. Subsequently strong collaterals developed. Definitive scrotal transfer was performed six weeks later through an inguinal incision. Two and a half years later, the testes had recovered very well. Their volume had increased markedly, and further development was normal.
