Ascent of the testis from the normal to an undescended position has been observed in 10 patients. In 9 of them there was a complete hernial sac and it is suggested that the acquired malposition of the testis is due to partial absorption of the processus vaginalis into the parietal peritoneum. Alteration in the length of the inguinal canal with growth may be an additional contributory factor. The mean interval between the original and subsequent observations was 5.2 years, leading to a late orchiopexy at a mean age of 9.4 years.
在10例患者中观察到睾丸从正常位置升至未降位置。其中9例有完整的疝囊，提示睾丸后天性位置异常是由于鞘突部分吸收进入腹膜所致。随着生长，腹股沟管长度的改变可能是另一个促成因素。最初观察与后续观察之间的平均间隔为5.2年，导致平均9.4岁时进行晚期睾丸固定术。
