We evaluated the correlation between a change in CKV and renal function recovery after PN. METHODS One hundred patients underwent PN between 2004 and 2009. Patients underwent open (73) or laparoscopic (27) PN Preoperative and postoperative (months 3, 6, and 12) kidney volumes were estimated using the Voxel Plus count method. GFR was determined using the Modification of Diet in Renal Disease formula. Demographic data and perioperative data were collected prospectively. RESULTS Mean 16.8 % of functional parenchyma was resected and the ipsilateral kidney volume (IKV) was increase in 3 month after PN. CKV was significantly increased immediately after PN (preoperative to month 3: p=0.012; months 3-6: p=0.015) and reached a plateau after 6 months (p=0.960). Factors that related to CKV increase was described in Table 1. Twelve months later, the mean GFR decreased by 90.9%. Significant predictors of GFR at month 12 were age <55 years, longer ischemic time, reduced %GFR at day 1, reduced IKV at month 3, and increased %CKV at month 12. The limitations of this study were the lack of separate GFR data and a short-term follow-up. A complementary study may be required. CONCLUSIONS Decreased functional volume remaining after resection results in greater CKV increase, and CKV increase contributes to renal function recovery after PN. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e447 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Woong Kyu Han Dallas, TX More articles by this author Seung Choul Yang Seoul, Korea, Republic of More articles by this author Kyung Hwa Choi Seoul, Korea, Republic of More articles by this author Koon Ho Rha Seoul, Korea, Republic of More articles by this author Young Deuk Choi Seoul, Korea, Republic of More articles by this author Sung Joon Hong Seoul, Korea, Republic of More articles by this author Hyung Ho Lee Seoul, Korea, Republic of More articles by this author Myung Soo Kim Seoul, Korea, Republic of More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
