ABSTRACT = {<b>Introduction:</b> To explore postoperative operation-side renal functional outcome after laparoscopic partial nephrectomy (LPN) using dynamic renal scintigraphy.<br/>
<b>Materials and methods:</b> Between July 2006 and December 2014, 62 patients with localized renal tumor received ischemic LPN at our institution. Preoperative, 6 months postoperative, and 12 months postoperative split renal functions were evaluated by dynamic renal scintigraphy using radionuclide technetium-99m-mercaptoacetyltriglycine. Postoperative operation-side renal function was calculated. To assess the significant factors affecting postoperative operation-side renal functional decrease, simple regression and multiple regression analyses were carried out.<br/>
<b>Results:</b> Postoperative operation-side renal functions were significantly decreased to 86.6% at 6 months and 86.9% at 12 months postoperatively (p < 0.0001). Simple regression analyses revealed that postoperative operation-side renal functions were significantly decreased with prolonged warm ischemia time at 6 months and 12 months postoperatively (p = 0.0058 and 0.0032, respectively). Multiple regression analysis identified warm ischemia time as an independent predictive factor for operation-side renal functional decreases at 6 months and 12 months postoperatively (p = 0.0158 and 0.0109, respectively).<br/>
<b>Conclusions:</b> Irreversible renal damage using dynamic renal scintigraphy after LPN was observed. With prolongation of warm ischemia time during LPN, postoperative operation-side renal function was significantly decreased.},
