目的

探讨肾肿瘤侵入指数(RTII)评分系统在后腹腔镜肾部分切除术治疗早期肾癌的临床应用价值。

方法

回顾性分析2015年1月至2020年12月在徐州医科大学附属淮安医院泌尿外科行后腹腔镜肾部分切除术治疗早期肾癌的临床资料。依据RTII评分系统将所有患者分为低、中、高度复杂组。比较各组的患者一般情况及围手术期相关指标。

结果

共有168例患者纳入本研究,其中低度复杂组74例,中度复杂组61例及高度复杂组33例。各组在性别(χ2=0.18,P=0.913)、年龄(F=2.41,P=0.312)、位置(χ2=0.36,P=0.841)、体重指数(F=2.97,P=0.475)及术前血肌酐水平(F=1.92,P=0.562)等方面比较无明显差异。RTII评分与手术时间(F=25.29,P=0.002)、热缺血时间(F=17.68,P=0.005)、术中出血量(F=37.26,P<0.001)及术后并发症方面(χ2=17.19,P<0.001)显著相关;而与术后住院时间(F=1.96,P=0.815)及术后血肌酐水平(F=1.21,P=0.295)无明显相关性。RTII评分系统预测术后并发症的精度较高(AUC=0.738,P<0.001),其中,敏感性为86.4%,特异性为51.4%;但是,各组之间并发症比较差异无明显统计学意义(Z=5.435,P=0.066)。

结论

RTII评分系统在肾癌后腹腔镜肾部分切除术中,对评估肿瘤的复杂性、预估手术难度及术后并发症发生风险有较好的临床应用价值。

Objective

To evaluate the clinical value of renal tumor invasion index (RTII) scoring system in laparoscopic partial nephrectomy for renal cancer.

Methods

The clinical data of patients with renal cancer who underwent retroperitoneal laparoscopic partial nephrectomy at the Department of Urology of Huai'an Hospital Affiliated to Xuzhou Medical University from January 2015 to December 2020 were analyzed retrospectively. According to the RTII scoring system, they were divided into three groups: low complexity group, medium complexity group, and high complexity group. The general situation and perioperative related indexes of patients in each group were compared.

Results

A total of 168 patients were included in this study, including 74 in the low complexity group, 61 in the medium complexity group, and 33 in the high complexity group. There was no significant difference in gender (χ2=0.18, P=0.913), age (F=2.41, P=0.312), side (χ2=0.36, P=0.841), body mass index (F=2.97, P=0.475), or preoperative blood creatinine level (F=1.92, P=0.562) among the three groups. In terms of perioperative related indexes, there were significant differences in operation time (F=25.29, P=0.002), warm ischemia time (F=17.68, P=0.005), intraoperative bleeding (F=37.26, P<0.001), and postoperative complications (χ2=17.19, P<0.001) among the three groups, though there was no significant difference in postoperative hospital stay (F=1.96, P=0.815) or postoperative serum creatinine level (F=1.21, P=0.295). RTII scoring system had high accuracy in predicting postoperative complications (area under the curve=0.738, P<0.001), with a sensitivity of 86.4% and specificity of 51.4%. However, there was no significant difference in complications among the three groups (Z=5.435, P=0.066).

Conclusion

RTII scoring system has good clinical value in evaluating tumor complexity and predicting the difficulty of operation and the risk of postoperative complications in laparoscopic partial nephrectomy for renal cancer.
