High-resolution ultrasound effectively locates undescended testes in most patients, proving superior to other imaging methods. This non-invasive technique aids in diagnosing testicular retention and impalpable testes, crucial for pediatric urology.

Area of Science:

  • Pediatric Urology
  • Diagnostic Imaging
  • Medical Ultrasound

Background:

  • Undescended testes (cryptorchidism) affect a significant number of male infants.
  • Accurate localization is essential for timely treatment and preventing complications like infertility or malignancy.
  • Palpability is not always indicative of testicular location, necessitating advanced imaging.

Purpose of the Study:

  • To evaluate the efficacy of high-resolution sonography in localizing undescended testes.
  • To compare sonography's effectiveness with other imaging modalities for testicular retention.
  • To determine the primary imaging method for impalpable and retained testes.

Main Methods:

  • Retrospective analysis of 18 patients with undescended testes.

  • High-resolution sonography utilized for imaging.
  • Comparison of sonographic findings with surgical or other imaging results.

    • Main Results:

    • Sonography successfully located 16 out of 17 testes in the inguinal or external iliac regions.
    • Two out of four intra-abdominal testes were identified using sonography.
    • Most retained and impalpable testes were found in superficial locations.

    Conclusions:

    • High-resolution sonography is the primary and most effective imaging modality for localizing undescended testes.
    • Ultrasound demonstrates significant utility in identifying testes in superficial inguinal and external iliac regions.
    • Further investigation into the roles of CT, MRI, and phlebography for complex cases is warranted.
