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.
