Step 2:
Differentiate palpable and non-palpable testis

For practical reasons, you should distinguish between patients with palpable (80%) and non-palpable (20%) testis, as the diagnostic workup and treatment differ between these two groups of patients.

Diagnostics for:

  • No imaging study is indicated. An orchidopexy is scheduled.
  • An ultrasound (US) might be beneficial in difficult-to-examine infants with a thick layer of fat in the groin.
  • The finding of compensatory contralateral testicular hypertrophy (>2 ml) indicates, with almost 90% probability, the absence of viable testicular tissue (anorchia, atrophy), which may be useful for planning the necessary operating time.
  • Helas, US nor Computed tomography (CT) and Magnetic Resonance Imaging (MRI) do not provide 100% sensitivity to detect intra-abdominal testes. Therefore, a diagnostic laparoscopy is recommended as the most appropriate diagnostic method.
