Evaluation of renal function after laparoscopic partial nephrectomy with renal scintigraphy using ^99mtechnetium‐mercaptoacetyltriglycine

Abstract

This paper evaluated renal function on the affected side before and after surgery by measuring split renal function with renal scintigraphy using (99m)Tc-MAG3. Risk factors for renal dysfunction in the affected kidney after LPN include age over 70 years with more than 30 min warm ischemic time, re-clamping of the renal artery procedure, and a warm ischemic time greater than 60 min. We believe that renal cooling with slush ice prevents renal dysfunction of the affected kidney after LPN with longer warm ischemic times. However, an easier renal cooling technique should be sought for regular use of cooling procedures in LPN.
