Enucleo-resection (ER), theoretically, should spare more parenchymal volume than healthy margin partial nephrectomy (HMP). We analyzed whether ER and HMP differed with respect to PFVP in patients who underwent RALPN. Methods We reviewed the records of 142 consecutive patients who underwent RALPN from June 2008 to September 2013. Patients were included in our analysis on the basis of having pre- and post-surgical imaging available. 65 patients met the inclusion criteria (ER n = 28, HMP n= 37). Renal parenchymal volumes were then assessed before and after surgery using 3D reconstruction software. PFVP of the operated-on kidney was then analyzed with respect ER and HMP. All averages are shown as mean ± SD. Results Among all patients, mean PFVP was 93.9 ± 10.1 %. Mean PFVP for HMP was 88.7 ± 9.6 %. Mean PFVP for ER was 98.4 ± 8.0 %. There was a statistically significant difference between mean PFVP for ER and HMP (9.8 ± 2.2 %, p < .001). Conclusions If previous reports of parenchymal volume preservation maximizing renal functional outcomes in RALPN are true, the differences in PFVP observed between ER and HMP could provide useful information for urologist looking to optimize patient care. When possible, urologists should utilize ER when performing RALPN in order to maximally preserve renal parenchymal volume, and by extension renal function. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e439 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Timothy Durso More articles by this author Robert Blackwell More articles by this author Adam Van Huis More articles by this author David Surprenant More articles by this author Patrick Sweigert More articles by this author Helyn Alvarez More articles by this author Jonathan Carnell More articles by this author Jessica Wetterlin More articles by this author Marcus Quek More articles by this author Robert Flanigan More articles by this author Gopal Gupta More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
