Discussion

A horseshoe kidney presents a unique anatomic challenge secondary to its low fixed location, abnormal vasculature, anterior renal pelvis, and presence of an isthmus. There are few reports of laparoscopic ablative and reconstructive surgery in horseshoe kidneys, of laparoscopic and retroperitoneoscopic heminephrectomies [1–4], and of hand-assisted pyeloplasty and isthmectomy [5]. Our literature survey revealed only one report of partial nephrectomy in a horseshoe kidney that had been performed by a retroperitoneal approach in a patient with a complex enhancing cyst [6]. To our knowledge, this is the first report of a partial nephrectomy in a horseshoe kidney carried out by means of a transperitoneal laparoscopic transperitoneal approach (Figs. 1–5). In our opinion, the choice of laparoscopic approach depends on tumour location: anterior, anterolateral, and isthmic locations are best approached transperitoneally, whereas posterior and posterolateral tumours are more suitable for a retroperitoneoscopic approach.
