METHODS The data of 51 patients with a unilateral renal tumor managed by partial nephrectomy were retrospectively analyzed. The RCV of tumor-bearing and contralateral kidneys was measured using ImageJ software. Split estimated glomerular filtration rate (eGFR) and SRV calculated using this RCV were compared with the split renal function (SRF) measured with 99mTc-DMSA renal scan. RESULTS A strong correlation between SRF and SRV of the tumor-bearing kidney was observed before and after surgery (r = 0.89, p < 0.001 and r = 0.94, p < 0.001). The preoperative and postoperative split eGRF of the operated kidney showed moderate correlation with SRF (r = 0.39, p = 0.004 and r = 0.49, p < 0.001). Correlation between reductions in SRF and SRV of the operated kidney (r = 0.87, p < 0.001) was stronger than that between SRF and percent reduction in split eGFR (r = 0.64, p < 0.001). CONCLUSIONS Compared with split eGFR, the SRV calculated using CT-based renal volumetry has a strong correlation with the SRF measured using 99mTc-DMSA renal scan. CT-based SRV measurement before and after partial nephrectomy can be used as a single modality for anatomical and functional assessment of the tumor-bearing kidney. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e784-e785 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Chan Ho Lee More articles by this author Ja Yoon Ku More articles by this author Hong Koo Ha More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
