title: The remnant orchiectomy.
abstract: OBJECTIVE
  We examined and characterized the histological features of remnant testicular tissue distal to the internal inguinal ring in boys who underwent exploration for a nonpalpable testis.
  
  
  METHODS
  The medical records and histology of 48 boys (50 remnants) who underwent exploration for a nonpalpable testis during a 10-year period were reviewed in detail.
  
  
  RESULTS
  Remnant tissue was characterized by evidence of ischemia and necrosis (scar, calcification, hemosiderin and hyalinization) suggestive of a vascular accident. Viable germ cells were identified in 5 remnants.
  
  
  CONCLUSIONS
  A 10% incidence of viable germ cells in remnant testicular tissue warrants exploration and removal of all remnant tissue in boys who undergo exploration for a nonpalpable testis.
