Abstract
It has been generally accepted that migratory (retractile) testis requires no treatment because retractibility ceases at puberty and the testis takes up a permanent scrotal position. In some patients, however, migratory testis is difficult to distiguish from true undescended testis. Several authors have also reported that histological changes were observed in migratory testis. Sixty-five children (4 to 9 years of age) with 92 migratory testes underwent orchiopexy. The surgery was indicated when 1) testis was usually located in inguinal area and rarely descended or was difficult to manipulate into scrotum, 2) scrotal position was high, 3) testis was small, or 4) ipsilateral scrotum was underdeveloped. The orchiopexy was easily performed through a scrotal incision. Tunica and cremaster muscle were transected and spermatic cord was elongated. Postoperatively, all the testes were located within the scrotum. It is concluded that a severe form of migratory testis should be treated by orchiopexy rather than being observed till puberty.
