Testicular ultrasound scanning was performed in 192 men with a history of cryptorchidism. The ultrasonic tissue pattern was evaluated and each testis was accordingly given a score on a scale from 1 to 4, 1 representing the normal uniform pattern and 4 being a very irregular pattern. Testicular biopsy of the previously maldescended testicle(s) was carried out in 143 of the scanned men and from two contralateral testicles where the score 4 was given at the ultrasound examination. Two biopsies showed carcinoma-in-situ pattern. Both were found among testes with a very irregular echo pattern. This pattern was found in only 3.2% of all scanned testes.
对192名有隐睾病史的男性进行了睾丸超声扫描。评估了超声组织模式，并据此给每个睾丸打1到4分，1分代表正常均匀模式，4分代表非常不规则的模式。在143名接受扫描的男性中，对先前下降异常的睾丸进行了活检，另外还对超声检查得分为4分的两个对侧睾丸进行了活检。两份活检显示原位癌模式。两者均在回声模式非常不规则的睾丸中发现。这种模式在所有扫描的睾丸中仅占3.2%。
