The medical reports of 113 patients operated upon for renal tumors were retrospectively reviewed to assess the value of preoperative embolization. Coils or ethanol were used preoperatively in 55 patients while 58 patients underwent nephrectomy without embolization. The tumors were staged according to the TNM and the Robson staging classification. T1 and T2 tumors as well as T3 and T4 tumors were grouped together for statistical evaluation. There was no significant difference in intraoperative blood loss, operation time and survival rate between patients undergoing preoperative embolization and those who had only nephrectomy. Duration of hospital stay was always longer in the preoperatively embolized group. Preoperative embolization of renal tumors neither improved the patients' outcome nor reduced the surgical risk. Robson's classification, stage III/IV, did not show any significant differences for embolized patients or for those nephrectomized without embolization.
对113例接受肾肿瘤手术的患者的医学报告进行回顾性分析，以评估术前栓塞的价值。55例患者术前使用了线圈或乙醇，而58例患者未进行栓塞直接接受了肾切除术。根据TNM和罗布森分期分类对肿瘤进行分期。将T1和T2期肿瘤以及T3和T4期肿瘤归为一组进行统计评估。术前接受栓塞的患者与仅接受肾切除术的患者在术中失血量、手术时间和生存率方面没有显著差异。术前接受栓塞的组患者住院时间总是更长。肾肿瘤术前栓塞既没有改善患者的预后，也没有降低手术风险。罗布森分类的III/IV期，在接受栓塞的患者和未接受栓塞而接受肾切除术的患者中没有显示出任何显著差异。
