The objective of this study was to compare open partial nephrectomy (OPN) and robotic-assisted PN (RAPN) based on a propensity score-matched sample and to test the Comprehensive Complication Index (CCI) as an end point for complications.
Patients undergoing PN from 2010 to 2018 at a university care center were included. OPN and RAPN cases were matched in a 2:1 ratio using propensity score-matching with age, gender, BMI, RENAL score, and tumor size as confounders. The primary end point was complications measured with the CCI as continuous score (0-100, 100 indicating death).
Data of 570 patients were available. After matching, both cohorts (OPN = 166; RAPN = 83) showed no baseline differences. For the primary end point, CCI, RAPN was superior (RAPN 2.6 ± 7.9 vs. OPN 8.7 ± 13.9; p < 0.001). Additionally, RAPN was superior for length of stay (RAPN 6.5 ± 4.0 vs. OPN 7.4 ± 3.5 days; p < 0.001), hemoglobin drop (RAPN 2.8 ± 1.4 vs. OPN 3.8 ± 1.6 g/dL; p < 0.001), and drop of glomerular filtration rate (RAPN 11.4 ± 14.2 vs. OPN 19.5 ± 14.3 mL/min; p < 0.001). OPN had shorter operating times (RAPN 157 ± 43 vs. OPN 143 ± 45 min; p = 0.014) and less ischemia (RAPN 13% vs. OPN 28%; p = 0.016).
RAPN provides superior short-term results regarding overall complications without compromising renal function for small and less complex tumors. However, OPN remains an important option for more complex and larger tumors.
本研究旨在通过倾向评分匹配样本比较开放部分肾切除术(OPN)和机器人辅助肾部分切除术(RAPN),并测试综合并发症指数(CCI)作为并发症的终点。
纳入 2010 年至 2018 年在大学医疗中心接受 PN 的患者。使用倾向评分匹配,以年龄、性别、BMI、RENAL 评分和肿瘤大小为混杂因素,将 OPN 和 RAPN 病例以 2:1 的比例匹配。主要终点是使用 CCI 作为连续评分(0-100,100 表示死亡)测量的并发症。
共 570 例患者的数据可用。匹配后,两组(OPN = 166;RAPN = 83)均无基线差异。对于主要终点,CCI,RAPN 更优(RAPN 2.6±7.9 比 OPN 8.7±13.9;p<0.001)。此外,RAPN 在住院时间(RAPN 6.5±4.0 比 OPN 7.4±3.5 天;p<0.001)、血红蛋白下降(RAPN 2.8±1.4 比 OPN 3.8±1.6 g/dL;p<0.001)和肾小球滤过率下降(RAPN 11.4±14.2 比 OPN 19.5±14.3 mL/min;p<0.001)方面也更优。OPN 手术时间更短(RAPN 157±43 比 OPN 143±45 min;p=0.014)且缺血时间更短(RAPN 13%比 OPN 28%;p=0.016)。
RAPN 在不影响肾功能的情况下,为小而不复杂的肿瘤提供了更短期的整体并发症结果,但 OPN 仍然是更复杂和更大肿瘤的重要选择。
