Abstract

Unilateral ureteronephrectomy was performed in a dog presented with unilateral hydroureter and hydronephrosis. On laparotomy, severe adhesion of the dorsomedial border of the affected kidney to the abdominal aorta longitudinally and caudal pole of the kidney firmly to the ipsilateral ovary were observed. Since it was not possible to ligate the renal artery and vein separately due to severe adhesion tissue, two mass ligations were applied in the medial border of kidney, and the adhesion tissue was transected distal to each ligature. Then, blunt and sharp dissections were performed to isolate dorsomedial border of the kidney from the abdominal aorta, but they brought out unexpected hemorrhage caused by incision of renal artery and it has been suspected that two mass ligations could not include renal artery, which was adhered to dorsomedial border of the kidney. The hemorrhage was controlled by double ligations and electrocautery. In this case report, we recommend that if isolation of renal vessels is impossible due to strict adhesion of kidney to adjacent tissue, the mass ligation could be chosen to isolate and exteriorize the kidney and placed carefully not only at medial border of the kidney, where the renal vessels come into the kidney anatomically but also additional border of the kidney where adhesion tissues are formed.

편측 수뇨관증과 수신증으로 내원한 개에서 편측성 신요관절제술을 시행하였다. 개복 시 유착조직이 신장의 안쪽 면에서부터 복대동맥 위까지 형성되어 있었으며, 등쪽안쪽면과 복대동맥 사이에 유착조직이 형성되어 있었다. 또한 좌측 난소가 신장의 꼬리쪽 극에 유착되어 있었다. 유착조직의 형성으로 인해 신장 동맥과 정맥을 구별하여 결찰하는 것이 불가능 하였기 때문에 신장의 안쪽면 두 곳에서 집단결찰을 시행한 후 유착조직을 신장의 안쪽면에서 분리하였다. 신장의 등쪽안쪽면과 복대동맥사이에 형성된 유착조직으로부터 신장을 분리하기 위해 유착조직을 절개해 나갈때 신장동맥의 절제로 인한 출혈이 발생하였다. 출혈의 원인은 복대동맥에서 분지되어 나온 신장동맥부위가 신장의 등쪽안쪽면과 유착이 되어있었기 때문에 신장의 안쪽면에 적용한 집단결찰에 신장동맥이 포함되지 못하였던 것으로 생각된다. 발생된 출혈은 절제된 신장동맥의 이중결찰과 전기소락기를 이용하여 멈추게 하였다. 본 증례를 통해, 신장이 주변복강 장기와 심하게 유착되어 신장 동, 정맥을 구별하여 결찰하기 힘든 경우 집단 결찰법을 선택할 수 있으며, 집단결찰법은 해부학적으로 신장 동, 정맥이 신장으로 들어가는 안쪽면 뿐만 아니라 유착이 형성된 신장의 모든 면에 선택적으로 적용되어야 한다고 생각한다.
