睾丸扭转导致睾丸的突然供血阻断,在大多数病例中,此种病变必需与附睾炎或睾丸附件的扭转相鉴别。由于睾丸炎大都与前列腺炎有关,因此鉴别诊断急性阴囊肿胀的最容易、最成功的实验室方法,可能是尿液检查。如果在首段排尿标本中未发现白细胞,应考虑睾丸扭转的诊断,并作出立即手术探查的计划。但如果诊断有怀疑,可以单独应用多普勒超声图或放射性同位 Testicular torsion leads to a sudden blockage of testis, which in most cases must be differentiated from torsion of epididymitis or testicular appendages.

However, if the diagnosis is suspect, Doppler ultrasound or radioisotope alone can be used
