title: [A case of laparoscopic heminephroureterectomy for ureter cancer in a horseshoe kidney].
abstract: We reported a case of laparoscopic heminephroureterectomy for ureter cancer in a horseshoe kidney. A 59-year-old woman presented with frequency and diagnosed as left lower ureter cancer with a horseshoekidney. We performed transperitoneal laparoscopic nephroureterectomy. Feeding vessels were four arteries and two veins. Isthmus of the horseshoe kidney was divided using LCS and hemostasis was made using monopolar shears. Operating time was 300 minutes. Total Blood loss was 400 ml. Laparoscopic pyeloplasty or ishmusectomy to benign disease of the horseshoe kidney is often reported, but that of heminephrectomy to malignancy is seldom reported. Laparoscopic Heminephectomy for a horseshoe kidney is difficult surgery for aberrant vessels and isthmus, so it tends to be avoided for safety. But if anatomical consideration about aberrant vessels etc is well done and we operate carfully, so we will be able to do it for safety and small invasive opration.
