微波组织凝固器在无阻断肾蒂肾部分切除术中的应用

Clinical application of microwave tissue coagulator in partial nephrectomy without blocking the renal hilum stalk

目的：探讨微波组织凝固器在无阻断肾蒂肾脏部分切除术中应用价值。方法：用微波组织凝固器对16例（17个肾脏）行肾脏部分切除术，术中未阻断肾蒂。结果：1例同时行双侧肾部分切除术患者手术时间为325min，15例手术时间为90～220min，平均为180min。术中出血量45～450ml，平均80ml。术前术后血肌酐无显著性差异。患者术后第2天即可下床活动。结论：微波组织凝固器在肾脏部分切除术中，具有微创、安全、出血少及操作简便等作用。

Objective：To evaluate the role of microwave tissue coagulator in partial nephrectomy without blocking the renal hilum stalk. Methods：Non-ischemic partial nephrectomy was performed in 17 kidneys of 16 patients using a microwave tissue coagulator in which the renal hilus stalk was not blocked. Results：The time for operation was ranged from 90 to 220 min （mean 180 min）. The estimated operative blood loss was about 45-450 ml （mean 80 ml）. There were no statistically significant differences between the pre-operative and the post-operative parameters in terms of renal function. All patients resumed activities 2 days postoperatively. Conclusions：Our initial resuits showed that microwave tissue coagulator was a minimally invasive, convenient and safe surgical technique with less blood loss while the partial nephrectomy without blocking the renal hilum was contemplated.
