Estimated functional renal parenchymal volume predicts the split renal function following renal surgery

Abstract

The postoperative FRV and renal function could be predicted preoperatively using a 3-D image reconstructive system, preoperative routine diagnostic imaging, and preoperative sCr level.

Clinical application of calculated split renal volume using computed tomography‐based renal volumetry after partial nephrectomy: Correlation with technetium‐99m dimercaptosuccinic acid renal scan data

“…To overcome the limitation of serum creatinine-based renal function evaluation, several studies have reported the usefulness of CT-based renal parenchymal volumetry. 18,19,25 According to these reports, there was a significant correlation between mean percent RPV loss and the mean percent eGFR loss (r = 0.52-0.79). However, although several reports have compared CT-based volumetry with nuclear renal scan in living kidney donors, there is no such report for nephron-sparing surgery.…”

“…To overcome the limitation of serum creatinine‐based renal function evaluation, several studies have reported the usefulness of CT‐based renal parenchymal volumetry . According to these reports, there was a significant correlation between mean percent RPV loss and the mean percent eGFR loss ( r = 0.52–0.79).…”

“…These studies have shown a significant correlation between SRF and SRV estimated by the two methods ( r = 0.46–0.93). As the quantity of the preserved parenchyma is an extremely strong independent predictor of ultimate renal function after nephron‐sparing surgery, this approach was also applied to postoperative renal function evaluation in patients who underwent partial nephrectomy . The aim of the present study was to evaluate the clinical application of CT‐based measurement of RCV and SRV in patients with renal tumors before and after partial nephrectomy, and compare the findings with 99m Tc‐DMSA renal scan data.…”

Comprehensive Analyses of Factors Associated with Postoperative Renal Global Function in Patients Treated by Partial Nephrectomy

“…Many 3-D simulation software packages enable researchers to estimate renal preservation by a detailed surgical process with computational methods [20,21]. In this study, sophisticated film technology, Synapse Vincent, was used for the soft volumetric analysis.…”

Editorial Comment from Dr Teishima and Dr Matsubara to Clinical application of calculated split renal volume using computed tomography‐based renal volumetry after partial nephrectomy: Correlation with technetium‐99m dimercaptosuccinic acid renal scan data

“…Lee et al addressed the clinical impact of split renal volume (SRV) calculated on the basis of the findings of computed tomography (CT) used to evaluate renal function in patients with renal cell cancer who underwent partial nephrectomy. 1 Previous studies have shown the correlation between renal parenchymal volume determined by CT-based renal volumetry and loss of estimated glomerular filtration rate, [2][3][4] and other studies of living kidney donors have compared the findings of CT-based renal volumetry and those of nuclear renal scans. [5][6][7] On the basis of the results of these studies, the present study shows the possible usefulness of CT-based volumetry along with nuclear renal scans for estimating split renal functions after nephron-sparing surgery.…”
