Abstract：Objective: To introduce the experience of digital kidney in localization of endophytic renal tumor during partial nephrectomy. Methods: Preoperative image showed an endophytic renal tumor. Digital kidney was reconstructed by MIMICS. The tumor was localized by calculating the distance from tumor to the upper or lower pole of the kidney as well as the outline of the lateral kidney. The data was utilized during laparoscopic surgery to localize the tumor and partial nephrectomy was performed. Results: Digital kidney can localize accurately the endophytic renal tumor, and coincide with the reality. Conclusions: Digital kidney is a simple and reliable method to localize the endophytic renal tumor during partial nephrectomy.
