目的:探讨孤立肾巨大肿瘤的诊治方法。方法:对2例孤立肾肾肿瘤直径≥8.0cm的患者,先行腹腔镜手术游离肾脏血管,再行开放手术将肾肿瘤剜除。结果:2例手术均获成功,1例术后发生肾功能不全,1例完全康复,术后随访12个月,肿瘤均无复发或转移。结论:对于孤立肾巨大肿瘤,术前行肾动脉血管检查、肾肿瘤超选择性栓塞,术中运用腹腔镜游离肾血管、开放手术冷缺血阻断肾动脉,使肿瘤与正常肾组织分界清楚、减少出血、加快手术操作、有助于保护患者肾功能,提高患者生活质量。
Objective: To investigate the diagnosis and treatment of isolated giant tumor of kidney. Methods: Two patients with isolated kidney and kidney tumors with a diameter of 8.0cm or more were treated with laparoscopic surgery to remove the renal blood vessels and then with open surgery to remove the renal tumors. Results: All of the 2 cases were successful. One case had renal insufficiency after operation and one case recovered completely. All the patients were followed up for 12 months without any recurrence or metastasis. Conclusions: For isolated renal giant tumors, renal artery angiography was performed preoperatively, superselective embolization of renal tumors, intraoperative laparoscopic free of renal blood vessels, open renal ischemia were performed to block the renal artery, and the boundary between the tumor and normal renal tissue was clear , Reduce bleeding, speed up the operation, help to protect patients with renal function, improve patient quality of life.
