Abstract:
Objective To explore the potential value of applying three-dimensional visualization technology in the robot-assisted laparoscopic nephron sparing partial nephrectomy.Methods From January to December 2018,98 patients with renal carcinoma undergoing robot-assisted laparoscopic nephron sparing surgery were retrospectively analyzed.Forty-one patients in the experimental group accomplished kidney CT examination and three-dimensional reconstruction before surgery,and fifty-seven patients in the control group only completed kidney CT examination.There were 20 males and 21 females in the experimental group with the age of (51.39 ± 14.80) years and body mass index (BMI) of (23.54 ± 3.08) kg/m2.The median tumor diameter was 3.40 cm (range 1.90-8.30 cm) and the mean R.E.N.A.L.score was (5.83 ± 1.51) in the experimental group including 11 cases of transperitoneal,17 cases of retroperitoneal and 13 cases of combined transperitoneal and retroperitoneal access.There were 35 males and 22 females in the control group with the age of (52.84 ± 12.28) years and BMI of (24.01 ±3.30)kg/m2.The median tumor diameter was 3.35 cm (range 1.40-7.0 cm) and the mean R.E.N.A.L.score was (6.17 ± 1.77) in the control group including 15 cases of transperitoneal,31 cases of retroperitoneal and 11 cases of combined transperitoneal and retroperitoneal access.There was no statistical difference between two groups in term of age,gender,BMI score,R.E.N.A.L.score,tumor size,tumor location and operative approach.Results Ninety-eight cases of operation were successfully completed without causing vascular and ureteral injury.The warm ischemia time in the experimental group was significantly shorter than that of the control group [median 15.0 (7.0-26.0) min vs.20.0 (10.0-28.0) min,P--0.02],while no statistical difference was observed in term of operation time [median 130.0 (65.0-340.0) min vs.139.0 (67.0-250.0) min,P =0.22].There was no significant difference between the two groups in the decrease of hemoglobin within 24 hours after operation [median 20.0 (4.0-39.0) g/L vs.15.5 (2.0-40.0) g/L,P =0.56] and the average length of hospital stay after operation [median 6.0(4.0-14.0) d vs.6.0(5.0-14.0) d,P =0.86].The trend of creatinine declining was not statistically significant between the two groups at both 24 hours [median:2.0 (-10.0-28.0) μmol/L vs.7.5 (-17.0-51.0) μ mol/L,P =0.24] and 6 months after operation [median:2.0 (-12.0-57.0) μ mol/L vs.4.5 (-3.0-24.0) μmol/L,P =0.39].Conclusions Preoperative three-dimensional reconstruction is helpful to shorten the warm ischemia time,but it did not show short-term and long-term protection for renal function.
