Retrocaval ureter is an uncommon abnormality of the inferior vena cava, which is rarely detected in the child due to its non-specific symptomatology. Despite a varying state of severity, chronic ureteral obstruction generally leads to the deterioration of renal function during adulthood. Treatment depends on the symptomatology in question, and surgical management should be as conservative as possible.

Retrocaval ureter: a case report and review of the literature.
J Med Case Rep

Background: The retrocaval ureter is a rare congenital anomaly resulting from abnormal development of the inferior vena cava. The obstruction is usually at the retrocaval segment of the ureter, as it lies between the inferior vena cava and the body of the third lumbar vertebra. Computed tomography intravenous urography is the gold standard for investigating this condition and can reveal ipsilateral hydronephrosis and the fishhook sign or sickle sign of the proximal ureter, depending on the type of retrocaval ureter.

Introduction: Retrocaval ureter is a rare congenital anomaly that causes ureteral obstruction. Because of the rarity of retrocaval ureter, only a few cases of open, laparoscopic, or robot-assisted surgery have been reported. We herein report a case of retrocaval ureter that was successfully reconstructed with robot-assisted surgery.

Hydronephrosis, characterized by the dilation of the renal pelvis and calyces, often results from obstructive uropathy, commonly due to ureterolithiasis. However, rare congenital anomalies, such as a retrocaval ureter (RCU)-where the ureter passes behind the inferior vena cava- can also cause hydronephrosis. This case report describes an 11-year-old male presenting with right-sided flank pain and hematuria.

Retrocaval ureter is a rare congenital anomaly. It usually occurs on the right side and cases on the left side without accompanying conditions such as situs inversus or double inferior vena cava (IVC) are uncommon. Instances of left retrocaval ureter without situs inversus or double IVC are rarely reported in the literature, and there are no cases presented sonographically.
