Retrocaval ureter is a rare congenital anomaly due to altered development of the vasculature, in which the ureter passes behind the inferior vena cava. This is often secondary vascular variants. Here we present a case about a 41-year-old woman with pain in the right renal fossa, stenotic retrocaval ringlet was established by CT scan. RG showed 43.3 ml/min with obstructive pattern and a bordering left renal exclusion. A laparoscopic transperitoneal approach was realized. Right pyeloureteromy and anteroposition was done. The patient evolved satisfactorily, showed no signs of inflammatory systemic response and continued under post-surgical surveillance until drainage was removed, with progressively diminished serohematic output. Laparoscopic ureteral antero-position with pyeloureterotomy is considered the treatment of choice because it’s a less invasive procedure. We recommend the laparoscopic approach because of a low postsurgical complications risk.
