Abstract No. 187 Utility of R.E.N.A.L. nephrometry scoring system in predicting complications and outcomes of percutaneous microwave ablation of renal tumors

Abstract

Results: Patients on anticoagulation had a longer mean catheter implantation time of 323.1 ± 592.0 days compared to 169.0 ± 224.8 days among patients not on anticoagulation, although this was not statistically significant (P ¼ 0.37). Antiplatelet therapy did not significantly delay fibrin sheath development (P ¼ 0.96). Right-sided catheters had a significantly longer mean implantation time of 195.9 ± 335.1 days versus 66.2 ± 58.0 days for left-sided catheters (P ¼ 0.008). Time to fibrin sheath formation was not significantly associated with statin medication (P ¼ 0.72), hematocrit (P ¼ 0.16), platelet count (0.12), PT (P ¼ 0.51), or INR (P ¼ 0.74). Conclusions: Anticoagulation may delay de novo fibrin sheath formation in patients with tunneled internal jugular 14.5 F symmetric tipped dialysis catheters. The time to fibrin sheath formation was significantly shorter among catheters placed on the left, and thus, tunneled dialysis catheters should be placed on the right side when feasible.
