In patients who have limited life expectancy or are high risk surgical candidates radio frequency ablation provides reasonable long-term oncological control and it may have a role in the management of small renal masses. Meticulous long-term followup is required in patients receiving radio frequency ablation.
p<0.001 ), and larger tumors (3.3 vs. 2.7 em, p=0.01 ). Intraoperative data, postoperative outcomes, complications, and pathologic data were similar between groups. At a mean follow-up of 8.1 months, the percent deterioration in serum creatinine and estimated glomerular filtration rate was similar between the groups (p=0.99 and 0.89, respectively). Dialysis, temporary or permanent, was required in 5 patients (10%) in Group I and 3 patients (0.6%) in Group II (p<0.001 ). Within group I, older patients (>70 years) with prolonged warm ischemia (>30 min) had significantly worse renal functional outcomes. Comparing groups I and II, estimated 5year overall survival was 78% versus 90% (Log-rank =0.01 ), and cancerspecific survival was 100% versus 98% (Log-rank=0.65).CONCLUSIONS: Laparoscopic partial nephrectomy with hilar clamping can be performed efficaciously and safely in select patients with compromised renal function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
