Nephron-Sparing Procedures May Preserve Renal Function Better
SAN FRANCISCO—Nephron-sparing techniques for treating renal masses smaller than 4 cm are more effective than radical nephrectomy (RN) in preserving renal function, a study shows.

Seventy-one patients were treated with RN, 85 with partial nephrectomy (PN), and 86 with radiofrequency ablation (RFA).
CKD stage 3 (glomerular filtration rate less than 60 mL/min per 1.73 m2) was 34 times and 11 times more likely to develop with RN when compared with RFA and PN, respectively. Findings were reported here at the 2008 Genitourinary Cancers Symposium and published recently in the Journal of Urology (2008;179:75-80).
