Comparison of the efficacy of robotic-assisted retroperitoneal laparoscopy and traditional retroperitoneal laparoscopy in partial nephrectomy among patients with renal tumors: A retrospective cohort study

PURPOSE: The efficacy of robotic-assisted retroperitoneal laparoscopy (RARL) and traditional retroperitoneal laparoscopy (TRL) in patients undergoing partial nephrectomy for treatment of a renal tumor were compared in this study. MATERIALS AND METHODS: The retrospective study reviewed patients with renal tumors who underwent partial nephrectomy in our hospital between January 2020 and February 2022. According to different surgical methods, the patients were enrolled into the RARL (experimental group, n=65) or the TRL (control group, n=63) partial nephrectomy group. RESULTS: One hundred twenty-eight patients were reviewed. The number of patients with collecting system injuries in the experimental group (19 cases) was significantly less than in the control group (32 cases; p<0.05). The operative time (115.7±48.2 min vs. 143.1±25.5 min) and heat ischemia time (18.7±4.9 min vs. 26.4±5.2 min) were significantly shorter in the experimental group than in the control group. The intraoperative blood loss (35.4±13.2 mL vs. 96.1±34.3 mL) and postoperative drainage volume (55.9±26.4 mL vs. 75.2±32.6 mL) were significantly less in the experimental group than in the control group (p<0.05). The change in postoperative glomerular filtration rate decrease in the experimental group was significantly lower than that in the control group (p<0.05). The change level in postoperative creatinine increase in the experimental group were significantly lower than those in the control group (p<0.05). There were no considerable differences in other clinical indicators or follow-up results between the two groups. CONCLUSIONS: RARL was superior to TRL for renal tumor treatment with respect to operative time, intraoperative blood loss, warm ischemia time, and postoperative renal function recovery.
