Abstract:
Retrocaval ureter (pre-ureteral vena cava) is an uncommon congenital anomaly that causes ureteral obstruction by external compression. Although right retrocaval ureter is a common entity, left retrocaval ureter is extremely rare. A left retrocaval ureter is usually associated with situs inversus or duplicated inferior venacava (IVC). An isolated left retrocaval ureter with single left-sided IVC is even rarer and only four cases have been reported in the literature. We present images of a case with isolated left retrocaval ureter with a single left-sided IVC without situs inversus.
