目的:探讨R.E.N.A.L.评分系统在后腹腔镜保留肾单位手术中的临床价值。方法:回顾性分析2007年1月~2011年6月T1a期肾癌患者29例应用R.E.N.A.L.评分系统进行量化评分资料,提出对评分系统的改进意见,并进行应用比较。结果:应用R.E.N.A.L.评分系统将29例患者分为高值7例(A组),中值10例(B组),低值12例(C组),A、B、C三组在热缺血时间存在明显差异(P<0.01),术中出血量、手术时间、住院时间差异无统计学意义(P>0.05)。改良R.E.N.A.L.评分系统后将29例患者重新分为高值9例(E组),中值10例(F组),低值10例(G组),E、F、G三组组间在热缺血时间、术中出血量、手术时间均存在明显差异(P<0.01)。结论:R.E.N.A.L.评分系统可以较好的对腹腔镜保留肾单位手术进行评估,但改良后R.E.N.A.L.评分系统可能更切合临床的手术实际操作。
Objective: To investigate the clinical value of R.E.N.A.L. scoring system in retroperitoneal nephron surgery. Methods: The data of R.E.N.A.L. scoring system in 29 patients with stage T1a renal cell carcinoma from January 2007 to June 2011 were retrospectively analyzed. Some suggestions for improving the scoring system were put forward and compared. Results: The RENAL score system was used to divide 29 patients into 7 groups with high value (group A), 10 patients (group B) and 12 patients (group C) with low value. Groups A, B, There was significant difference in time (P <0.01). There was no significant difference in intraoperative blood loss, operation time and hospital stay (P> 0.05). In the modified RENAL score system, 29 patients were redivided into 9 patients with high value (group E), 10 patients (group F) and 10 patients (group G) Ischemic time, intraoperative blood loss, operation time were significantly different (P <0.01). CONCLUSIONS: The R.E.N.A.L.Scoring system can be a good assessment of laparoscopic nephron surgery, but the modified R.E.N.A.L. scoring system may be more suitable for clinical practice.
