Abstract:
Objective To explore the application value of different Trocar layouts in retroperitoneal laparoscopic partial nephrectomy for localized renal cell carcinoma, so as to provide reference for the layout of Trocar during operation. Methods The data of 137 patients with localized renal cell carcinoma who underwent retroperitoneal laparoscopic partial nephrectomy in our hospital during Sep. 2021 and Sep. 2024 were retrospectively collected, including 68 patients with umbrella layout(umbrella group)and 69 with trapezoidal layout(trapezoidal group). The operation-related indexes, renal function(glomerular filtration rate, serum creatinine), traumatic stress indexes including C-reactive protein(CRP), cortisol, and interleukin-6(IL-6), complications and recurrence rate were compared between the two groups. Results There were no significant differences in pathological results, negative rate of surgical margins, hospitalization time, complications, 1-year recurrence rate, 6-month glomerular filtration rate and serum creatinine between the two groups(P＞0.05). Compared with the trapezoidal group, the umbrella group had less intraoperative blood loss [(72.11±18.30)mL vs.(87.59±20.63)mL], shorter operation time [(88.15±16.92)min vs.(99.40±20.78)min], renal warm ischemia time [(14.68±4.60)vs.(19.27±6.11)min], bowel sound recovery time [(21.00±5.75)h vs.(25.78±4.89)h] and ambulation time [(1.72±0.48)d vs.(2.04±0.55)d](P＜0.05). The umbrella group had lower CRP [(10.02±2.78)mg/ L vs.(12.00±3.15)mg/ L] on the first day after surgery, lower CRP [(7.89±0.76)vs.(8.77±1.25)mg/L] on the third day after surgery, lower cortisol [(0.67±0.20)μmol/L vs.(0.89±0.28)μmol/L] on the first day after surgery, lower cortisol [(0.58±0.15)μmol/L vs.(0.69±0.12)μmol/L] on the third day after surgery, lower IL-6 [(28.20±6.74)ng/L vs.(35.16±7.30)ng/L] on the first day after surgery, and lower IL-6[(21.25±5.39)ng/L vs.(29.78±4.26)ng/L] on the third day after surgery(P＜0.05). Conclusion Compared with the trapezoidal Trocar layout, the umbrella Trocar layout for retroperitoneal laparoscopic partial nephrectomy in patients with localized renal cell carcinoma offers advantages such as minimal surgical trauma, shorter operation and renal warm ischemia time, and faster postoperative recovery.
