Background: Retrocaval ureter (RCU), also termed pre-ureteral vena cava, represents an uncommon congenital anomaly in which the ureter passes posterior to the inferior vena cava (IVC). Although the malformation originates during embryogenesis, symptoms often manifest in adulthood, typically during the third or fourth decade of life. The estimated incidence is approximately 1 in 1500 individuals, with a male predominance (M:F ratio of 3:1). Methods: This series reports five cases of retrocaval ureter evaluated for demographic profile, clinical presentation, laterality, and the extent of hydronephrosis. Each patient underwent open uretero-ureterostomy with insertion of a double-J stent. Results: Postoperative outcomes were favorable in all cases. Stents were removed after three weeks, and follow-up at three months showed complete resolution of symptoms and satisfactory urinary drainage. Conclusion: Open uretero-ureterostomy provides excellent functional outcomes in patients with symptomatic retrocaval ureter. Keywords: Retrocaval ureter, Inferior vena cava, Hydroureteronephrosis, Uretero-ureteral anastomosis.
