后腹腔镜肾蒂阻断下保留肾单位肾肿瘤手术(附6例报告)

目的 探讨后腹腔镜肾蒂阻断下保留肾单位治疗肾肿瘤的方法及手术技巧. 方法收治肾脏外生性实体肿瘤6例患者,其中.肾细胞癌2例,肿瘤直径分别为2.5 cm和2.2 cm;肾错构瘤4例,肿瘤直径为2.5～3.5 cm.经后腹腔镜径路在自制的肾蒂阻断装置中阻断肾蒂,做保留肾单位的肾肿瘤手术,术中距肿瘤0.5～1.0cm处行肾脏部分切除术,创面缝合止血.结果 6例手术均成功,手术时间120～210min,中位数150min.术中出血150～200ml,中位数170ml.肾蒂血流阻断时间18～33 min,中位数22 min.2例肾细胞癌术后切缘阴性.术后随访6～12个月,未见肿瘤残留及复发.结论 后腹腔镜肾脏部分切除术中应用自制的肾蒂阻断装置,具有良好的止血效果、手术创伤小、视野清晰、操作方便、能最大限度地保留患肾等优点,术后恢复良好.

Retroperitoneal laparoscopic nephron-sparing surgery for renal tumor (a report of 6 cases)

Objective To evaluate the methods and efficacy of retroperitoneal laparoscopic nephron-sparing surgery for the treatment of renal tumor. Methods A total of 6 patients with renal tumors underwent retroperitoueal laparoscopie nephron-sparing surgery during warm ischacmia. Among the 6 eases, 2 had malignant tumor with the diameter of 2.5 cm and 2.2 cm,and 4 had renal angiomyolipoma with the diameter from 2.5 cm to 3.5 cm.The renal yes,Is were secured by a self-made equipment. Tumors were excised with a cold Endo-shear. Parenehymal edges were approximated using a absorbable hemostatic gauze. Results All procedures were successfully completed without open conversion. Mean surgical time was 150 minutes (range 120-210 minutes). Mean ischaemia time was 22 minutes (range 18-33 minutes) and the mean blood loss was 170 ml (range 150-200 ml). Surgical margins were negative in all patients.During a follow-up for 6-12 months, no patient had local or port site recurrence. Conclusions Betroperitoneal laparoscopic nephron-sparing surgery for renal tumor by using serf-made equipment is safe and effective. This procedure has the advantages of minimal invasion, less blood loss, good vision, and rapid convalescence and so on.
