摘要
目的 探讨经腹膜后隙途径腹腔镜活体供肾切取的技术和效果。方法 32名供者中，男性15名，女性17名。29例取左肾，3例取右肾。供者全身麻醉，取侧卧位，共选3个穿刺点，第1个穿刺点选在12肋缘下2cm与骶棘肌外侧缘1cm交叉点，第2个穿刺点选在第1个穿刺点向前8～10cm，或肋缘下2cm与腋前线交叉点，第3个穿刺点位于髂棘上2cm与腋中线交叉点，分别插入12mm、10mm和5mm的Trocar。以自制水囊扩张器扩张腹膜后隙，游离供肾和输尿管，前6例用直线切割缝合器切断肾动脉和静脉，后26例用带锁的塑料夹夹闭切断肾动脉和静脉，在第1个穿刺点向下的延长切口将肾取出。结果 32只供肾切取顺利，手术耗时60～180min，出血量20～200ml，供肾热缺血时间3～8min，冷缺血时间25～50min。3只肾静脉较短，分别为1cm、1．5cm和2cm，另有1只供肾动脉内膜损伤。移植术后第1d，受者的尿量为2800-10 100ml，无移植肾功能恢复延迟发生。结论 经腹膜后隙途径腹腔镜活体供肾切取是安全、可行的，对供者创伤小，所获供肾的质量较好，但要求有熟练的腹腔镜技术。
Objective To evaluate the technique and effect of laparoscopic live donor nephrectomy via retroperitoneal approach. Methods Thirty-two donors （15 males and 17 females） underwent laparoscopic donor nephrectomy at our institution. Twenty-nine left and 3 right procedures were performed. Under general anesthesia, all donors were placed in lateral decubitus. Three transretroperitoneal trocars were used through different ports. The first 12 mrn port was placed 2 cm inferior to the edge of rib and 1 cm lateral to the edge of sarcospinous muscle. The second 10 mm port was about 8 to 10 cm anterior to the first, or on the anterior axillary line and 2 cm inferior to the edge of rib. The third 5 mm port was also on the anterior axillary line but 2 cm superior to the iliac crest. The surgeon created the retroperitoneal working space with a constructed catheter balloon device, and made the donor kidney and ureter dissociated. Renal arteries and veins were cut with endoscopic articulating linear stapler for the first 6 patients and then with Hemo-Lok, a plastic clip with a lock, for the others. Finally, the dissected donor kidney and ureter were taken out through an incision extended from the first trocar port. Results All the 32 donor grafts were dissected successfully. The duration of procedure was ranged from 60 to 180 min, and the volume of blood loss was from 20 to 200 ml. The range of warm ischemia time was 3 to 8 min, and 25 to 50 min of cold ischemia time. Short renal veins were found in 3 cases, 1 cm, 1. 5 cm and 2 cm respectively. And one case of renal endoarterial injury occurred. On the day after transplantation, the urine volume of recipients was from 2800 to 10 100 ml. There was no delayed graft function found in recipients. Conclusion Laparoscopic donor nephrec tomy via re;troperitoneal approach is available and safe to renal transplantation with minimal invasion to donors. It can help to obtain donor grafts with higher quality, though skillful laparoscopic technique is demanded.
