Laparoscopic heminephroureterectomy for urothelial carcinoma in a horseshoe kidney

A 75-year-old man with gross hematuria for 10 months received a diagnosis of urothelial carcinoma in the left moiety of a horseshoe kidney. Laparoscopic heminephroureterectomy was performed smoothly and without perioperative complications. Preoperative computed tomography angiography was shown to be a valuable imaging modality for evaluating anatomical variations, and the laparoscopic approach was effective for managing malignancy in a horseshoe kidney.
