Perinephric Fat

Abstract Background Adherent perinephric fat (APF), characterized by inflammatory fat surrounding the kidney, can limit the isolation of renal tumors and increase the operative difficulty in laparoscopic partial nephrectomy (LPN). The aim of this study was to investigate the predictors of APF and its impact on perioperative outcomes during LPN. Methods A total of 215 consecutive patients undergoing LPN for renal cell carcinoma (RCC) from January 2017 to June 2019 at our institute were included. We divided these patients into two groups according to the presence of APF. Radiographic data were retrospectively collected from preoperative cross-sectional imaging. The perioperative clinical parameters were compared between the two groups. Univariate and multivariate analyses were performed to evaluate the predictive factors of APF. Results APF was identified in 41 patients (19.1%) at the time of LPN. Univariate analysis demonstrated that APF was significantly correlated with the male gender (P = 0.001), higher body mass index (P = 0.002), lower preoperative estimated glomerular filtration rate (P = 0.004), greater posterior perinephric fat thickness (P< 0.001), greater perinephric stranding (P< 0.001), and higher Mayo Adhesive Probability (MAP) score (P< 0.001). The MAP score (P< 0.001) was the only variable that remained an independent predictor for APF in multivariate analysis. We found that patients with APF had longer operative times (P< 0.001), warm ischemia times (P = 0.001), and greater estimated blood loss (P = 0.003) than those without APF. However, there were no significant differences in surgical approach, transfusion rate, length of postoperative stay, complication rate, or surgical margin between the two groups. Conclusions Several specific clinical and radiographic factors including the MAP score can predict APF. The presence of APF is associated with an increased operative time, warm ischemia time, and greater estimated blood loss but has no impact on other perioperative outcomes in LPN.

Significant Difference

Background: We analyzed differences in patient selection and perioperative outcomes between robotic-fellowship trained and non-fellowship trained surgeons in their initial experience with robotic-assisted laparoscopic partial nephrectomy. Methods: Data through surgeon case 10 was analyzed. Forty patients were identified from two fellowship trained surgeons (n = 20) and two non-fellowship trained surgeons (n = 20). Results: Fellowship trained surgeons performed surgery on masses of higher nephrometry score (8.0 vs. 6.0, p = 0.007) and more posterior location (60 vs. 25%, p = 0.03). Retroperitoneal approach was more common (50 vs. 0%, p = 0.0003). Fellowship trained surgeons trended toward shorter warm ischemia time (25.5 vs. 31.0 min, p = 0.08). There was no significant difference in perioperative complications (35 vs. 35%, p = 0.45) or final positive margin rates (0 vs. 15%, p = 0.23). Conclusion: Fellowship experience may allow for treating more challenging and posterior tumors in initial practice and significantly more comfort performing retroperitoneal robotic-assisted laparoscopic partial nephrectomy.

Clinical Records

Abstract Background: Nephrometry scores play a critical role in the preoperative evaluation of partial nephrectomy. Although score comparisons have been performed for transperitoneal or open surgery, systematic comparisons for retroperitoneal operations are lacking.Methods: We retrospectively evaluated the clinical records of patients who underwent partial nephrectomy at one center by one surgeon. Scores were generated according to the imaging results, and each score was categorized into low-, intermediate- and high-complexity groups. Then, the differences in perioperative outcomes were compared among the groups. We assessed whether the scores and sex, body mass index (BMI), age, or American Society of Anesthesiologists (ASA) Physical Status classification could predict whether the warm ischemia time (WIT) was likely be longer than 20 min and whether they could predict postoperative complications worse than Clavien–Dindo 1. The interobserver variability between two experienced surgeons for these scores was calculated with the intraclass correlation coefficient (ICC).Results: A total of 107 patients were ultimately evaluated. The median tumor size was 36.88 mm, and the median WIT, total operation time (OT) and estimated blood loss (EBL) were 18.97 min, 80 min, and 100 ml, respectively. Significant differences in WIT were identified among the complexity groups for each scoring system. Significant differences were identified between the OTs associated with the DAP and RENAL score complexity groups. The scores included in this study were significantly associated with the probability of having a WIT >20 min and high-grade postoperative complications. Receiver Characteristic Operator (ROC) curves showed that there were no significant differences in their predictive power. NePhRo had the highest agreement (0.839), followed by DAP (0.827). RENAL was superior to SPARE and PADUA, which were 0.758, 0.724 and 0.667, respectively.Conclusions: The scores included in this study were useful for preoperative assessment of retroperitoneal laparoscopic partial nephrectomy. No significant differences were observed among the scores in terms of their ability to predict prolonged hot ischemia time or high-grade postoperative complications. DAP is a good score in the retroperitoneal circumstance when its consistency is taken into account.
