The present report is concerned with two cases of the horseshoe kidney. During the dissecting practice at Gifu University School of Medicine in 1991, the case 1 was found in a female Japanese cadaver of 84 years old and the case 2 in a female Japanese cadaver of 84 years old and the case 2 in a female Japanese cadaver of 85 years old. 1) In both cases, the two kidneys were united at their lower ends across the midline of the body. The part of fusion called the isthmus consisted of renal tissues. 2) In both the cases 1 and 2, the hilus of each kidney opened anteriorly, and the ureters passed in front of the isthmus and entered the urinary bladder normally. The location of each kidney was lower than that of the normal kidney. 3) Surplus arteries arising from the abdominal aorta were observed in the cases 1 and 2. In the case 1, one surplus artery entered the left kidney and the isthmus. In the case 2, five surplus arteries were observed; two arteries entered the right kidney, one the left kidney and two the isthmus. 4) The incidence of the horseshoe kidney during the dissecting practice at Gifu University School of Medicine from 1971 to 1991 was 0.33% (three out of 908 bodies). 5) In both the cases 1 and 2, no malformation was observed in other organs.
本报告涉及两例马蹄肾病例。1991年在岐阜大学医学院解剖实习期间，病例1发现于一名84岁日本女性尸体，病例2发现于一名85岁日本女性尸体。1）在这两例中，两个肾脏在其下端越过身体中线相连。融合部分称为峡部，由肾组织构成。2）在病例1和病例2中，每个肾脏的肾门向前开放，输尿管从峡部前方经过并正常进入膀胱。每个肾脏的位置低于正常肾脏。3）在病例1和病例2中观察到有多余的动脉发自腹主动脉。在病例1中，一条多余动脉进入左肾和峡部。在病例2中，观察到五条多余动脉；两条进入右肾，一条进入左肾，两条进入峡部。4）1971年至1991年岐阜大学医学院解剖实习期间马蹄肾的发生率为0.33%（908具尸体中有3例）。5）在病例1和病例2中，其他器官均未观察到畸形。
