A few months after any therapeutic intervention, Doppler ultrasonography of the testis is advised to ensure perfusion is normal and to exclude testicular atrophy 3. In the majority of cases, the preoperative high-resistance flow to the testis is substituted for low-resistance flow that resettles postoperatively 8. Differential diagnosis

Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction.
