Abstract

Control of intraoperative bleeding is the main technical difficulty encountered during laparoscopic partial nephrectomy. The objective of this study was to compare the efficacy and morbidity of three renal parenchymal hemostasis techniques: high-frequency bipolar electrical current, high-frequency unipolar spray electrical current, and ultrasound during laparoscopic partial nephrectomy performed in pigs without vascular control. A standardized laparoscopic transperitoneal right lower-pole partial nephrectomy was performed in 27 pigs with a mean weight of 65 +/- 5 kg. The pigs were divided into three groups according to the technology used: Group 1 = bipolar electrical current, Group 2 = unipolar spray electrical current, and Group 3 = ultrasound. Intravenous urography was performed on the 28th day. The kidneys were then removed for histologic examination, and the pigs were sacrificed. The criteria evaluated were intraoperative and postoperative complications, blood loss, renal function, and thickness of the parenchymal lesions induced. The Kruskal-Wallis nonparametric test for comparison of medians was used for statistical analysis of the data (P < 0.05). Data from pigs that died before the end of the study were excluded from t...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
