摘 要:目的:探讨腹腔镜下肾部分切除术不同热缺血时间对术后早期肾功能的影响,明确肾脏热缺血安全时间。方法回顾性分析2012年10月至2014年6月76例行腹腔镜下肾部分切除术患者的临床资料。根据术中不同热缺血时间分成3组:A 组(28例),热缺血时间<20 min;B组34例,20 min≤热缺血时间<30 min;C组14例,热缺血时间≥30 min。术中所有患者均行单独肾动脉阻断。采用99 Tcm-二亚乙基三胺五乙酸肾动态显像检测手术前后分肾肾小球滤过率( GFR)值的变化。比较术前、术后1周、术后1个月、术后3个月GFR值,明确安全的肾脏热缺血时间,并观察早期肾功能恢复情况,采用多元回归方法分析早期肾功能损害的独立危险因子。结果 C组患侧肾脏GFR[数据以M(Q1,Q3)表示]术后1周、1个月、3个月较术前下降了19.43(17.70,22.06)、17.04(13.94,20.70)、13.82(10.72,18.73) ml/min, A 组分别为12.07(10.91,13.42)、10.04(9.16,11.75)、8.44(7.07,9.72) ml/min,B 组分别为13.64(12.48,16.72)、10.29(9.17,14.27)、9.63(7.85,12.59) ml/min。 C组降低程度明显高于A、B两组,差异有统计学意义( P<0.05)。 C组总肾GFR术后3个月较术前下降(10.70±4.93) ml/min, A、B 两组为(5.64±4.12)、(6.37±4.32) ml/min,C组下降程度明显高于A、B组,差异有统计学意义( P<0.05)。3组术后1周、1个月总肾GFR差异无统计学意义( P>0.05)。回归分析结果显示热缺血时间是术后早期肾功能损害的独立危险因子( P<0.001)。结论腹腔镜下肾部分切除术后早期肾功能损害的主要影响因素是热缺血时间,术中应尽量将热缺血时间控制在30 min内。热缺血时间≥30 min对术后肾功能损害程度大,并且早期总肾功能恢复缓慢。Objective To assess the effect of variable durations of warm ischemia on renal function early after laparoscopic partial nephrectomy ( LPN ) and make the definite safety duration of renal warm ischemia.Methods The clinical data of 76 patients treated with LPN from October 2012 to June 2014 were retrospectively analyzed.The patients were divided into 3 groups based on warm ischemic time,namely group A (28 cases) with warm ischemia time less than 20 min,group B (34 cases) with warm ischemia time more than 20 min and less than 30 min, group C ( 14 cases ) with warm ischemia time more than 30 min.LPN was performed with renal artery clamping alone in all the patients.Preoperative and postoperative renal scintigraphic scan was performed to access glomerular filtration rate ( GFR) in all patients.The GFR values were compared among before, 1 week, 1 month and 3 months after operation.The factors predicting the early renal injury were assessed by multivariate regression analysis.Results The renal GFR of the kidney underwent LPN decreased 19.43(17.70,22.06) ml/min at 1 week,17.04(13.94,20.70) ml/min at 1 month,13.82(10.72,18.73) ml/min at 3 months after the surgery in group C,respectively.In group A, the renal GFR of the operated-side decreased 12.07(10.91,13.42) ml/min,10.04(9.16,11.75) ml/min, 8.44(7.07,9.72) ml/min,respectively.In group B, the renal GFR of the operated-side decreased 13.64 (12.48,16.72) ml/min,10.29(9.17,14.27)ml/min,9.63(7.85,12.59) ml/min,respectively.The GFR decreased greater in group C than that in group A and B(P<0.05).The total renal GFR decreased (10.70 ± 4.93)ml/min at three months in group C,compared with (5.64 ±4.12)ml/min in group A and (6.37 ± 4.32)ml/min in group B,respectively.The decreased value in group C was greater than that in group A and B(P<0.05).However,the differences of the total renal GFR among the 3 groups were not significant at 1 week and 1 month(P>0.05).The multivaria
