Laparoscopic nephrectomy in dogs: An initial experience of 16 experimental procedures

Abstract

Left laparoscopic nephrectomy was performed in 16 dogs to describe the surgical techniques and initial experiences associated with operation time and surgery complications. The renal vein and artery were occluded by three ligating clips, respectively, and the ureter was sectioned after ligation with ligating clips at the level of the iliac vessels. A morcellation technique was used to remove the kidney from the abdominal cavity after placing it into a specimen retrieval bag. Total operation time and time spent for each different surgical stage in the first five operations were compared with those in the last five of the 16 operations. The factors that affected the differences of total operation time were examined, including sex, body-weight, number of operations, incision length, and surgical stages. Six intra-operative complications occurred including splenic hemorrhage (3 cases), torn specimen retrieval bag during kidney morcellation (1 case), and subcutaneous emphysema (2 cases). Surgical time for laparoscopic nephrectomy was affected primarily by the time spent for renal vascular pedicle section and could be decreased as the number of cases increased. Thus, laparoscopic nephrectomy using ligating clips and morcellation for kidney removal could be considered where nephrectomy is indicated in dogs. (C) 2013 Elsevier Ltd. All rights reserved.
