The laparoscopic diagnosis of transverse testicular ectopia.

Transverse testicular ectopia is a rare but well documented abnormality in which both testes descend through 1 inguinal canal. We report on a 14-month-old boy in whom laparoscopy was diagnostic for this abnormality. Laparoscopic examination of the pelvis is imperative to rule out the presence of müllerian remnants that commonly occur in patients with transverse testicular ectopia. Our case further supports the use of laparoscopy in patients with nonpalpable undescended testes.
