Abstract:Abstract: Objective?To evaluate the feasibility and effectiveness of holographic image navigation in robot-assisted laparoscopic partial nephrectomy (RAPN) for renal hilar tumors.?Methods?The clinical data of 11 patients who underwent RAPN for renal hilar tumors with holography during June to October of 2019 were respectively analyzed. There were 3 males and 8 females with an average age of 62.6 years (range 32 to 75 years), the average body mass index of 23.75?kg/m2 (range 19.45 to 28.12?kg/m2), 4 cases of left and 7 cases of right renal tumors. The average tumor diameter was 2.76?cm (range 1.1 to 6.7?cm). The mean GFR is 35?mL/min (range 22 to 51?mL/min). The R.E.N.A.L. score was 10.7 (range 8 to 12). Holography based on enhanced CT data was applied for the purpose of precise separation, enucleation the tumor with the Da Vinci robot-assisted system. The operative time, warm ischemia time, intraoperative blood loss, complications, and oncologic outcomes were analyzed.?Results?According to the holographic image, all operations were completed successfully and there was no open conversion and large vessel injury. The average operation time was 90 min (60?~?130 min), estimated blood loss was 100?mL (50?~?180?mL), warm ischemic time was 21 min (18?~?25 min), There was no postoperative fever, secondary blood loss, urine leakage or other complications. Pathologically, there were 9 cases of clear cell renal cell carcinoma (Fuhrman grade Ⅰ?~?Ⅱ), 1 case of papillary renal cell carcinoma, and 1 case of angioleiomyolipoma, Surgical margins were negative for malignancy in all cases. At a mean follow-up period of 4.3 months, the mean GFR is 31?mL/min (range 18 to 43?mL/min) without any disease recurrence.?Conclusions?It is safe and effective for renal hilar tumors to use holographic image navigation in robot-assisted laparoscopic partial nephrectomy, which has less perioperative complications.
