Complication and Readmission Rates following Same-Day Discharge after Percutaneous Renal Tumor Ablation

Purpose: to evaluate readmission rate and complications, in Patients Undergoing same-day discharge following percutaneons thermal ablation of renal tumors. Materials and Methods: Patients undergoing same day discharge following thermal ablation of renal tumors were reviewed. The primary outcome Was the rate of readmission within 30 days of same day discharge. The secondary outcomes included the rate and clinical outcomes of periprocedural complications: . Results:. Same-day, discharge occurred in 1661174 patients (95%), of whom 2/166 (1%) required short-term readmission due to pulmonary embolism and acute-on-chronic:kidney injury:, Both patients recovered without permanent Morbidity. Admission due to complications occurred in 8/174 (5%) cases, the majority of which Were related to hemorrhage. No Significant differences in rates of complications or admission were found between cryoablation and RF ablation. Major complications (Clavien-Dindo grade II or higher, SIR grade C or higher) occurred in 7/174 (4%) cases, the majority related to :hemorrhage: All cases were detected in the standard 4 hour postprocedural observation period and managed conservatively. The mean hemorrhage volume was significantly larger in patients requiring admission versus those discharged the same day (289 mL vs 34 mL; P = .02). Higher volume hemorrhage occurred in larger tumors (Mean, 4.0 cm vs 3.0 cm;; P = .04).. There was no association between major, complications and central tumor Or age. Conclusions: Routine, same-day discharge-following percutaneous renal tumor thermal ablation can be performed with a low rate of short-term readmission. The majority of, periprocedural complications' can be managed conservatively, and patients can be discharged the same day.
