An argon beam coagulator was evaluated in 25 canine partial nephrectomies to determine its hemostatic capabilities, safety and degree of thermal injury to renal parenchyma. Comparison was made with a control group of seven partial nephrectomies performed by standard technique. In both groups the procedure was performed without renal cooling or clamping of the renal artery. The argon beam coagulator was operated with a power output of 130 watts. Mean operative time for partial nephrectomy was 22 minutes in the control group versus 10 minutes when the argon coagulator was used (p less than 0.001). Mean blood loss was 276 cc by standard technique but only 135 cc with the argon coagulator (p less than 0.001). A regular eschar with a mean depth of tissue necrosis of 2.4 mm. was observed with the argon coagulator.
在25例犬部分肾切除术中对氩束凝固器进行评估，以确定其止血能力、安全性以及对肾实质的热损伤程度。将其与采用标准技术进行的7例部分肾切除术的对照组进行比较。两组手术均未进行肾降温或肾动脉夹闭。氩束凝固器的输出功率为130瓦。对照组部分肾切除术的平均手术时间为22分钟，而使用氩凝固器时为10分钟（p<0.001）。采用标准技术时平均失血量为276毫升，而使用氩凝固器时仅为135毫升（p<0.001）。使用氩凝固器观察到有规则的焦痂，组织坏死平均深度为2.4毫米。
