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 diagnosisTesticular torsion occurs when a testis torts on the spermatic cord resulting in the cutting off of blood supply. The most common symptom is acute testicular pain and the most common underlying cause, a bell-clapper deformity. The diagnosis is often made clinically but if it is in doubt, an ultrasound is helpful in confirming the diagnosis.The testicular microlithiasis is defined by the presence of concentric laminated calcifications up to 1 mm diameter (microliths) in the testicular parenchyma. Two types, classic (more than five microliths by ultrasound field) and limited (five or less microliths per ultrasound field) are distinguished.In 2015, a subcommittee of ESUR (the European Society of Urogenital Radiology) published a guideline on the management of microlithiasis using ultrasound, ... and testicular atrophy, but ...An acquired cause of small testes is testicular atrophy, which entails a testicular volume reduction of 20% compared with baseline volume or the normal contralateral testis [1,3].
