Laparoscopic Cranial Plication in Pelviureteral Junction Obstruction by Aberrant Lower Pole Artery

Abstract

Although currently the number of patients is small and follow-up is short, this procedure appears to be effective in relieving both symptoms and obstruction in patients with lower-pole crossing vessels. Other benefits include shorter operative time, less blood loss, as well as no risk of anastomotic stricture and urine leak when compared with a dismembered pyeloplasty. The Double-J stent can be removed within a few days (typically 5 in our hands) or even shorter where logistically feasible. This reduces stent-related complications.
