〔Abstract〕 Objective To compare the outcomes of “Trifecta” and “Pentafecta” in laparoscopic partial nephrectomy between patients receiving modified and traditional technique, and to further evaluate the value of safety and renal function preservation of the modified technique and determine its indication. Methods 80 patients including 40 receiving modified technique and 40 receiving traditional technique were recruited before clinical data of baseline, perioperative and follow-up were collected and analyzed. Results No significant difference in the incidence of complications, positive margin, recurrence, as well as the trifecta achievement had been found between groups.The achievement of pentafecta in group of modified technique was better than the group of traditional technique.Older age, larger diameter of tumor and lower preoperative eGFR had been found to be the independent risk factors of pentafecta failure in the group of traditional technique, with the cut-off value being 64 years, 35 mm and 73 ml/(min·1.73 m2) respectively. Conclusion The modified technique does not increase the risk of complications and has advantages of renal function preservation and pentafecta achievement in patients with older age, larger tumor and worse renal function.
