Perioperative Morbidity

AbstractThere are several nephrometry scoring systems for predicting surgical complexity and potential perioperative morbidity. The R.E.N.A.L. scoring system, one of the most well-known nephrometry scoring systems, emphasizes the features on which it is based (Radius, Exophytic/endophytic, Nearness to collecting system or sinus, Anterior/posterior, and Location relative to polar lines). The ability of these nephrometry scoring systems to predict loss of renal function after robotic partial nephrectomy (RPN) remains controversial. Therefore, we verified which combination of factors from nephrometry scoring systems, including tumor volume, was the most significant predictor of postoperative renal function. Patients who underwent RPN for cT1 renal tumors in our hospital were reviewed retrospectively (n = 163). The preoperative clinical data (estimated glomerular filtration rate [eGFR], comorbidities, and nephrometry scoring systems including R.E.N.A.L.) and perioperative outcomes were evaluated. We also calculated the tumor volume using the equation applied to an ellipsoid by three-dimensional computed tomography. The primary outcome was reduced eGFR, which was defined as an eGFR reduction of ≥ 20% from baseline to 6 months after RPN. Multivariable logistic regression analyses were used to evaluate the relationships between preoperative variables and reduced eGFR. Of 163 patients, 24 (14.7%) had reduced eGFR. Multivariable analyses indicated that tumor volume (cutoff value ≥ 14.11 cm3, indicating a sphere with a diameter ≥ approximately 3 cm) and tumor crossing of the axial renal midline were independent factors associated with a reduced eGFR (odds ratio [OR] 4.57; 95% confidence interval [CI] 1.69–12.30; P = 0.003 and OR 3.50; 95% CI 1.30–9.46; P = 0.034, respectively). Our classification system using these two factors showed a higher area under the receiver operating characteristic curve (AUC) than previous nephrometry scoring systems (AUC = 0.786 vs. 0.653–0.719), and it may provide preoperative information for counseling patients about renal function after RPN.

394 Background: Laparoscopic and robotic partial nephrectomy (LPN and RPN) are increasingly common minimally invasive alternatives to open partial nephrectomy (OPN) for management of renal tumors. The cost discrepancies of these approaches warrants evaluation. We compared hospital costs associated with RPN, LPN, and OPN. Methods: Variable hospital costs including operating room (OR) time, supplies, anesthesia, inpatient care, radiology, pharmacy, and laboratory charges were captured for 25 patients who underwent OPN, LPN, and RPN at our institution between 11/2008 -9/2010. Fixed costs of acquisition of a laparoscopic suite and a robotic system (including maintenance) were amortized over 7 years. We considered alternative scenarios through one-way and multi-way sensitivity analysis. Results: We found similar overall variable costs for OPN, LPN, and RPN. Sensitivity analysis demonstrated that RPN and LPN are more cost effective than OPN (excluding fixed costs) if the average hospital stay is < 2 days, or OR time less is than 204 and 196 mins, respectively. By including fixed costs of equipment, RPN and LPN are always more costly than OPN. Conclusions: There was no difference among variable hospital costs of OPN, LPN, and RPN. Minimizing OR time and hospital stay reduces RPN and LPN costs to levels comparable to OPN. Inclusion of fixed costs makes LPN and RPN more expensive than OPN, but increased utilization and efficiency can decrease cost per case. [Table: see text]

Abstract BackgroundTo compare the perioperative outcomes of Robotic partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN). MethodsWe searched PubMed, EMBASE and the Cochrane Central Register for studies from 2000 to 2020 to evaluate the perioperative outcomes RPN and LPN in patients with a RENALnephrometry score≥7. We used RevMan 5.2 to pool the data. ResultsSeven studies were acquired in our study. No significant differences were found in the estimated blood loss (WMD: WMD: 34.49, 95% CI -75.16-144.14, p=0.54), hospital stay (WMD: -0.59 95% CI -1.24–0.06, p=0.07), operating time (WMD: -22.45, 95%CI: -35.06 to-9.85, ), postive surgical margin (OR: 0.85, 95% CI 0.65–1.11, p =0.23) and transfusion (OR: 0.72, 95% CI 0.48–1.08, p =0.11).between the two groups. RPN get better outcomes in postoperative renal function (WMD: 3.32, 95% CI 0.73–5.91, p=0.01), warm ischenia time (WMD: -6.96, 95% CI -7.30–-6.62, p <0.0001), conversion( OR: 0.34, 95%CI: 0.17 to 0.66, p=0.002) and intraoperative complication (OR: 0.52, 95% CI 0.28–0.97, p=0.04).ConclusionRPN could get better perioerative clinical outcomes than LPN for treatment of Complex Renal Tumors( with a RENALnephrometry score≥7).
