External validation of the ability of the mRENAL nephrometry score to identify patients at risk for major adverse events or local tumor recurrence after percutaneous renal cryoablation.

Purpose: The purpose of this study was to evaluate the ability of the mRENAL score to identify patients at risk of either major adverse events (AEs) and/or local tumor recurrence (LR) after percutaneous cryoablation (PCA) in an external patient population.

Methods: Patient demographic data were recorded. The RENAL and mRENAL nephrometry scores were calculated.

Same-day discharge after percutaneous renal cryoablation and its effect on 30 day hospital re-admission rates and post-procedural complications.

Purpose: The purpose of this study is to identify if the local institutional shift from routine overnight observation to same-day discharge following percutaneous cryoablation (PCA) of renal tumors increases 30 day re-admission rates or serious adverse events (AEs).

Materials And Methods: This retrospective study included 133 adult patients. PCA patients in calendar years 2018-2019 were routinely observed overnight in the hospital, comprising the control group (Group A).
