Renal cell carcinoma in horseshoe kidney treated with retroperitoneoscopic partial nephrectomy: A case report

Horseshoe kidney complicated with renal malignancy is rare, the incidence and prognosis are not much different from those in the general population, However, due to the unique anatomical characteristics of the horseshoe kidney, the partial nephrectomy of horseshoe kidney is difficult and challenging. A 41-year-old female who incidentally found a right kidney 59 mm ∗ 45 mm solid mass combined with a horseshoe kidney. We successfully performed a retroperitoneal laparoscopic partial nephrectomy. For laparoscopic partial nephrectomy, in order to accurately judge the blood supply of horseshoe kidney and reduce intraoperative bleeding and complications, CT angiography and 3-dimensional (3D) reconstruction are very important.
