The testicular regression syndrome--do remnants require routine excision?

Aim: Excision of testicular remnants is debatable in the scenario where hypoplastic vas and vessels can be seen entering a closed internal ring during laparoscopy for impalpable testes. We aimed to establish how frequently excised remnants have identifiable testicular tissue and, hence, malignant potential.

Methods: This study is a retrospective review of all excised testicular remnants in children with impalpable testis.
