To evaluate the impact of extended warm ischemia on incidence of acute kidney injury (AKI) and ultimate functional recovery after partial nephrectomy (PN), incorporating rigorous control for loss of parenchymal mass, and embedded within comparison to cohorts of patients managed with hypothermia or limited warm ischemia.From 2007 to 2014, 277 patients managed with PN had appropriate studies to evaluate...
To assess surgical outcomes between the non-renorrhaphy and renorrhaphy techniques in open partial nephrectomy for ≥T1b renal tumors using volumetric studies.We retrospectively analyzed the records of 91 patients with normal contralateral kidneys who underwent both open partial nephrectomy for ≥T1b renal tumors and pre- and postoperative enhanced computed tomography between 2010 and 2014. Volumetric...
To validate the findings of a prior single-surgeon series with a multi-institutional comparison of three-dimensional imaging of volume preservation (3DVP) and surgeon assessment of volume preservation (SAVP) as predictors of renal function after partial nephrectomy (PN). Baseline renal function and preservation of functioning renal parenchyma are the strongest predictors of function after PN for presumed...
To compare freehand scripting and semiautomated renal parenchymal volume measurements on preoperative or postoperative computed tomography scans and assess relationships between parenchymal volume loss and functional changes within the operated kidney after partial nephrectomy (PN).Fifty patients (16 solitary kidneys, 34 bilateral kidneys) with renal tumors managed by PN with necessary studies for...
Ischemia is a potential contributor to decline of function after partial nephrectomy (PN), although loss of parenchymal mass related to excision and reconstruction appears to be a more significant factor. However, loss of parenchymal mass could also be due to global effects of ischemia leading to parenchymal atrophy. In this study, we evaluated parenchymal volumes in regions away from the operated...
To assess perioperative morbidity and margins after conventional clamped partial nephrectomy (PN) while also using volumetric analysis to differentiate the contributions of parenchymal volume loss and recovery from ischemia.The study analyzed 163 patients who underwent PN with appropriate studies to allow analysis of function and parenchymal mass specifically in the operated kidney. Recovery from...
