目的总结分析我科26例后腹腔镜保留肾单位手术(nephron-sparing surgery,NSS)治疗肾肿瘤的临床资料并复习国内外相关文献,为后腹腔路径NSS的适应证、治疗方法、并发症及治疗效果进一步提供实践与理论依据。方法选择T1NoMo、直径为1.7～4.5cm的局限性肾肿瘤患者26例。经后腹腔镜行NSS,术中阻断肾动脉。用剪刀距肿瘤边缘0.5～1.0cm的正常组织处切割。用生物蛋白胶、止血纱布及可吸收线缝合创面等方法彻底止血。结果 26例手术均成功完成。平均手术时间130(60～160)min、术中出血量50～300ml、肾动脉阻断时间平均20min、住院时间10～14d且均无严重并发症。术后患者肾功能正常。随访3～15个月,影像学检查未见肿瘤局部复发与转移。结论在严格进行病例选择和术者操作熟练的前提下,后腹腔镜NSS效果好、恢复快、切实可行。 Objective To summarize and analyze the clinical data of 26 cases of nephron-sparing surgery (NSS) treated by retroperitoneal laparoscopy and to review the relevant literature at home and abroad for indications, treatment and complications of retroperitoneal pathological NSS Therapeutic effects further provide practical and theoretical basis. Methods T1NoMo, diameter of 1.7 ~ 4.5cm in 26 patients with localized renal tumors. After laparoscopic NSS, intraoperative renal artery occlusion. Cut with scissors at normal tissue 0.5-1.0 cm from the edge of the tumor. With biological protein glue, stop bleeding gauze and absorbable suture wounds and other methods to completely stop bleeding. Results 26 cases were successfully completed. The average operation time was 130 (60 ~ 160) min, the intraoperative blood loss was 50 ~ 300ml, the average renal artery occlusion time was 20min, the hospitalization time was 10 ~ 14d and no serious complication occurred. Postoperative patients with normal renal function. Followed up for 3 to 15 months, no local tumor recurrence and metastasis were detected by imaging examination. Conclusions Under the condition of strict choice of case and skill of operation, the effect of retroperitoneal NSS is good, quick recovery and practicable.
