We performed laparoscopic live donor nephrectomy (LDN) on approximately 200 patients in Ehime Prefectural Center Hospital between 2003 and 2016. In 2016, a fifty-something woman who was a donor candidate for her husband was revealed to have a horseshoe kidney through contrast-enhanced computed tomography; other LDN procedures used a retroperitoneal approach, but this one used a transperitoneal approach since the latter approach allowed for a more favorable visual field. The left kidney was selected since renal scintigraphy showed equal bilateral renal function and renal arteries are simpler on the left side. The kidney was removed after the isthmus was successfully transected without ischemia. The opened calyx in the left kidney was sutured via bench surgery, and the kidney was transplanted to the recipient. Postoperative courses of both donor and recipient were good.
