Use of 5F bipolar electrosurgical probe in endoscopic urological procedures.

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.
