[Present state of studies on anatomical anomalies in cryptorchidism]

Cryptorchidism is a clinically common congenital deformity of the genital organ, the etiological factors of which are still not clarified up to now. Undescended testis is frequently accompanied with the anomalies of the spermatic cord, gubernaculum testis, processus vaginalis, and epididymis. Because these anatomical anomalies act as terminal factors or the ending in the links of the cause of cryptorchidism, it is of important directive significance for the clinical treatment of the problem to seek evidence of anatomical anomalies at orchiopexy to demonstrate the etiological factors of cryptorchidism.
