07 and 0.08, respectively).

Conclusions: Although salvage partial nephrectomy is technically demanding and it has a high complication rate, it allows many patients to avoid dialysis. We believe that this experience can be used as a reference for surgeons and patients when considering the risks and benefits of salvage partial selleck kinase inhibitor nephrectomy.”
“Purpose: Elective nephron sparing surgery is established as an alternative to radical nephrectomy for renal cell carcinoma if tumors are small (4 cm or less, stage T1a). We compared outcomes in patients

with renal cell carcinoma 4 cm or less (small) vs more than 4 cm (large) who were treated with nephron sparing surgery.

Materials and Methods: Between 1979 and 2006, 618 patients underwent elective nephron sparing surgery at our institution. Of these patients 474 (76.7%) had renal cell carcinoma, which was 4 cm or less in 372 (78.5%) and more than 4 cm in 102 (21.5%). Followup was 4.7 (range 0.1 to 23.9) years for small and 4.7 (range 0.1 to 24.1) years for large tumors. Cancer specific survival and local recurrence free survival were estimated.

Results: The estimated cancer specific survival rate at 5 years was 97.9% and 95.8%, and at 10 years it was 94.9% and 95.8% for small and large tumors, respectively (log rank p = 0.583). The survival

rate free of local recurrence at 5 years was 98.5% and 98.3%, and at 10 years it was 93.9% and 98.3% for small and large tumors, respectively (log rank p = 0.282). In contrast to tumor size, stage 3 was associated with a significant

higher risk of tumor related death.

Conclusions: Elective Selleck ICG-001 nephron sparing surgery is oncologically safe in select patients with localized renal cell carcinoma more than 4 cm. In our series MAPK inhibitor the selection criterion for choosing elective nephron sparing surgery rather than radical nephrectomy over the years has consistently been safe surgical resectability rather than tumor size. However, there is a correlation between tumor size and unfavorable pathological tumor characteristics, which prompts caution when choosing elective nephron sparing surgery for all large tumors.”
“Purpose: We examined the effect of radical nephrectomy, partial nephrectomy and radio frequency ablation on renal function in patients with stage T1a renal masses.

Materials and Methods: A total of 242 consecutive patients from July 1995 to March 2005 undergoing primary treatment for unilateral renal masses smaller than 4 cm and a normal contralateral kidney were identified. Renal function was calculated using the modified Modification of Diet in Renal Disease equation. The rate of decrease in the glomerular filtration rate below 60 ml per minute 1.73 m(2) was compared among the 3 treatment modalities.

Results: A total of 86, 85 and 71 patients were treated with radio frequency ablation, partial nephrectomy and radical nephrectomy, respectively.
