Functional Comparison of Renal Tumor Enucleation Versus Standard Partial Nephrectomy.

Background: Tumor enucleation (TE) optimizes parenchymal preservation and could yield better function than standard partial nephrectomy (SPN), although data on this are conflicting.

Objective: To compare functional outcomes for TE and SPN strategies.

Design, Setting, And Participants: Patients managed with partial nephrectomy (PN) with necessary data for analysis of preservation of ipsilateral parenchymal mass (IPM) and global glomerular filtration rate (GFR) from two centers were included.

Functional Implications of Renal Tumor Enucleation Relative to Standard Partial Nephrectomy.

Objective: To compare the surgical precision for optimizing nephron-mass preservation of tumor enucleation (TE) vs standard partial nephrectomy (SPN), with primary focus on functional outcomes. TE is presumed to optimize preservation of parenchymal mass and function but this has not yet been rigorously studied and quantified.

Materials And Methods: Robotic partial nephrectomy patients who had appropriate pre- and postoperative studies for analysis of parenchymal mass preservation specific to the operated kidney were included.
