摘      要：Objectives:To compare the depth of thermal necrosis after use of bipolar resection and vaporization technique comparing intra-individually bipolar loop and bipolar button ***:Transurethral resection and vaporization of the prostate was performed in 55 male patients(260 specimens in total).In a standardized procedure,a bipolar resection loop was used for resection,and a bipolar button electrode was used for *** electrodes were applied in each patient,either in the left or in the right lateral *** depth of necrotic zones in the resected or vaporized tissue of each patient was measured in a standardized way by light ***:The mean depth with standard deviation of thermal injury caused by the loop electrode was 0.0495±0.0274 *** vaporization electrode caused a mean thermal depth with standard deviation of 0.0477±0.0276 *** mean difference of necrosis zone depths between the two types of electrodes(PlasmaButtoneresection loop)was 0.0018 mm(p=0.691).Conclusion:For the first time,we present directly measured values of the absolute necrosis zone depth after application of plasma in the transurethral treatment of benign prostatic *** measured values were lower than in all other transurethral *** procedures of measurement and evaluation allow a statistically significant statement that the low necrosis depth in bipolar procedures is independent of the applied electrodes.
