目的探讨后腹腔镜保留肾单位手术对局限性肾癌的疗效。方法对24例患者行后腹腔镜下保留肾单位手术。术后观察是否出现创面出血,尿漏,每3个月复查腹部B超,胸部CT,肾功能。结果 24例手术均顺利完成,术后无继发性出血、2例出现轻度漏尿。随访10~26个月,平均18个月,无一例出现局部复发,远处转移。结论后腹腔镜保留肾单位手术治疗局限性肾肿瘤是安全有效的方法值得推广。 Objective To investigate the effect of retroperitoneal laparoscopic nephron surgery on localized renal cell carcinoma. Methods 24 patients underwent retroperitoneal laparoscopic nephron surgery. Postoperative observation of wound bleeding, urinary leakage, abdominal ultrasound every 3 months review, chest CT, renal function. Results All the 24 cases were successfully performed. No postoperative hemorrhage occurred and 2 cases had slight leakage of urine. All patients were followed up for 10 to 26 months, with an average of 18 months. None of the patients had local recurrence or distant metastasis. Conclusions Retroperitoneal laparoscopic nephron sparing surgery is a safe and effective method to treat localized renal tumors.
