Abstract A 22‐year‐old woman was diagnosed with a duplicated renal collecting system with hydronephrosis and parenchymal loss in the upper pole of the left kidney. She underwent laparoscopic left upper‐pole nephrectomy. Although a complex hilar vascular anatomy was identified during the operation, preoperative three‐dimensional computed tomographic reconstruction using a three‐dimensional image analysis device (Synapse Vincent; Fuji Medical Systems, Tokyo, Japan) greatly helped to accurately identify the anatomical renal hilum. For further detail, virtual partial nephrectomy analysis using a Voronoi decomposition was used to visualize the area supplied by a selected arterial branch including the atrophic cleavage line. We controlled the bleeding with selective clamping and safely carried out upper‐pole heminephrectomy according to the preoperative plan.
