Experimental data have shown bipolar electrodes to function in saline solution with less volume and depth of tissue destruction compared to similar sized monopolar electrodes. We applied the same bipolar generator and electrodes used in laboratory testing in 41 procedures on 36 patients to determine if the bipolar electrode will provide clinically adequate hemostasis. The bipolar electrode was used for bladder fulguration in 37 procedures and ureteral fulguration in 4. The procedures were performed by 7 urological surgeons and in normal saline solution. The bipolar electrode was believed to perform as well as the standard monopolar probe in 39 procedures. The 2 failures included 1 bladder tumor fulguration and 1 electroincision of a ureterointestinal anastomotic stricture. There were no episodes of recurrent bleeding after any procedure. The bipolar system has the added advantage of not requiring a return electrode (ground pad), thereby eliminating the possibility of skin burns.
实验数据表明，与尺寸相似的单极电极相比，双极电极在盐溶液中发挥作用时，组织破坏的体积和深度更小。我们将实验室测试中使用的同一双极发生器和电极应用于36例患者的41项手术中，以确定双极电极是否能提供临床上足够的止血效果。双极电极在37项手术中用于膀胱电灼，在4项手术中用于输尿管电灼。这些手术由7名泌尿外科医生在生理盐水溶液中进行。在39项手术中，双极电极被认为与标准单极探头表现相当。2例失败病例包括1例膀胱肿瘤电灼和1例输尿管肠吻合口狭窄的电切。任何手术后均无复发出血情况。双极系统的额外优势是不需要回路电极（接地垫），从而消除了皮肤烧伤的可能性。
