ABSTRACT
Objective To evaluate the safety,efficiency of retroperitoneal laparoscopic partial nephrectomy combined with four points location in 3D model or 3Dimensional CT for completely endophytic tumors,and summarize the surgical experience.Methods From Jan 2015 to Jan 2016,5 patients with completely endophytic tumors,who underwent retroperitoneal laparoscopic partial nephrectomy were recruited.one patient underwent 3D printing kidney model,and another 4 patients underwent 3Dimensional CT and locating four projection positions of the tumor on the surface,in order to guide the tumor resection in laparoscopic partial nephrectomy.Perioperative,operative,and postoperative,as well as oncological outcomes were analyzed.Results In all 5patients,preoperative four points location in 3D model or 3Dimensional CT for completely endophytic tumors is feasible and accurate in term of locating the tumor.The mean operative time was(129.0 ± 19.5) min,mean warm ischaemia time was (19.6 ± 5.4) min and mean estimated blood loss was(100 ± 83) ml.Pathological examination showed cell renal cell carcinoma.All the patients had a negative surgical margin,and no tumor recurrence or metastasis during 6-18months of follow up.Conclusions In experienced institutes,retroperitoneal laparoscopic partial nephrectomy combined with four points location in 3D model or 3Dimensional CT for completely endophytic tumors is a feasible and safe procedure in terms of accurate locations,low complication rates,reasonable functional and oncologic outcomes after an intermediate-term follow-up
