Open Partial Nephrectomy without Ischemia

Background: Vascular clamping during partial nephrectomy could induce to renal ischemia and kidney’s damage due to reperfusion injuries. Adverse effect on renal function can be eliminated by Zero ischemia techniques.The aim of this study was to assess the feasibility of performing partial nephrectomy under a situation of being ready to clamping renal artery. Methods: 24 patients with solitary small renal masses were recruited to the study between 2013and 2018. Open partial nephrectomy was performed for them. During the time corresponding to hilar vessels clamping in standard procedures, we have reached to the renal artery and ready for clamping if needed, and in this situation resection of the mass was assessed. Results The mean age of patients was 42 years. The tumor resection time was 22 minutes averagely. The median procedure time was 92 minutes, Clear cell RCC was found in 19 patients, papillary RCC in 3 and oncocytoma in 2 with no positive surgical cancerous margin in specimens. Lower pole, midzone and upper pole masses were found consequently in14, 2 and 8 cases. Conclusions: Although this technique could be a dangerous decision making in a well exposed renal artery, especially in Polar Regions, the tumor resection can be safely conducted without ischemia.
