ＴＵＲＰ是治疗症状性膀胱出口梗阻手术的黄金标准 ,但具有并发出血和灌注液吸收的危险。近几年来 ,为减少围手术期并发症的发生 ,曾试图改变电极形状和改进高频发生器以减少出血而不增加其电流 ,如电凝、间断电切法使用普通电切镜和改进的高频发生器。这种技术使用恒定电压脉 TURP is the gold standard for surgical treatment of symptomatic bladder outlet obstruction, but poses the risk of concurrent bleeding and perfusion fluid uptake. In recent years, in order to reduce the occurrence of perioperative complications, attempts have been made to change the electrode shape and improve the high-frequency generator to reduce bleeding without increasing its current, such as electrocoagulation, intermittent electrosurgical resection using ordinary resectoscopes and improved High-frequency generator. This technique uses a constant voltage pulse
