Introduction Horseshoe kidney has unique anatomical features, such as a complex blood supply. We report a patient with renal cell carcinoma in a horseshoe kidney, who underwent tumor resection by robot‐assisted laparoscopic partial nephrectomy based on preoperative three‐dimensional computed tomography. Case presentation A 66‐year‐old man was referred to our hospital with a 2‐cm enhancing mid‐pole mass in the left moiety of a horseshoe kidney. The clinical diagnosis was renal cell carcinoma cT1aN0M0 (R.E.N.A.L. nephrometry score: 1 + 2 + 3 + 3 = 9p). Robot‐assisted laparoscopic partial nephrectomy was performed with selective clamping based on reconstructed three‐dimensional images. The warm ischemia time was 13 min. Pathologic examination confirmed a diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins. At 6 months postoperatively, computed tomography showed no local recurrence or metastasis and renal function was intact. Conclusion Robot‐assisted laparoscopic partial nephrectomy with preoperative three‐dimensional computed tomography may have advantages for resection of tumors in patients with horseshoe kidney.
