Objective To investigate the feasibility of bidirectional barbed suture in retroperitoneal laparoscopic partial nephrectomy without blocking renal artery. Methods There were 29 cases of kidney tumors patients were treated by retroperitone-al laparoscopic partial nephrectomy with blocking renal artery. There were 7 cases were treated by retroperitoneal laparoscopic par-tial nephrectomy with not blocking renal artery with the help of bidirectional barbed suture. Comparison between two groups of sur-gical time, intraoperative bleeding volume, postoperative bleeding, changes of serum creatinine and complications. Results Sur-gical time, intraoperative bleeding volume, postoperative bleeding and Changes in preoperative and postoperative serum creatinine were no significant difference in two groups(P>0. 05). Two groups were both no serious complications. Conclusions Retroper-itoneal laparoscopic partial nephrectomy with not blocking renal artery with the help of bidirectional barbed suture is feasible, does not increase operation difficulty and complications.%目的 探讨双向倒刺缝合线在不阻断肾动脉的后腹腔镜肾部分切除术中应用的可行性. 方法 收集2007年10月至2012年12月的29例行传统的阻断肾动脉的后腹腔镜肾部分切除术的局限性肾肿瘤患者29例,2013年1月至2014年12月的7例行应用双向倒刺缝合线的不阻断肾动脉的后腹腔镜肾部分切除术患者. 比较两组手术时间、术中出血量、术后出血量、术后术前肌酐升高值和并发症的差异,了解应用双向倒刺缝合线的不阻断肾动脉的后腹腔镜肾部分切除术的可行性. 结果 两组治疗的手术时间、术中出血量、术后出血量以及术后术前肌酐升高值的差异无统计学意义(P>0. 05). 两组病例均未发生严重并发症. 结论 应用双向倒刺缝合线可以实现不阻断肾动脉下的后腹腔镜肾部分切除术,与传统手术有相似的效果,不增加严重并发症的发生.
