A 72-year-old male was diagnosed incidentally with a 7-cm renal tumor in the right moiety of a horseshoe kidney during a routine physical examination, and was treated with laparoscopic radical heminephrectomy. The surgical time was 153 min and the estimated blood loss was 150 ml. The patient was discharged on post-operative day eight with no complications. Computed tomography angiography is desirable prior to surgery for the evaluation of the anatomical variations of horseshoe kidneys, and a pre-operative understanding is necessary for achieving reliable vascular control. In conclusion, the present technique is safe and effective for this complex clinical condition.
