Abstract

Objective To study the diagnosis and treatment of retrocaval ureter. Mathods 10 cases of retrocaval ureter were reported. The diagnosis of this disease depends on imaging examinations, such as intravenous urography (IVU), retrograde ureterography (RU) or MR urography (MRU).Surgical operation was used to treat this disease. The compressed retrocaval portion of ureter was resected and end to end anastomosis was performed anterior to the vena cava in all the 10 cases. Results All the 10 cases were correctly diagnosed preoperatively. IVU and RU or MRU showed right hydronephrosis with reversed “J shaped”or “S shaped” ureter. B ultrasound and IVU revealed improvement of hydronephrosis and no ureter stenosis was observed postoperatively. Conclutions IVU and RU were the first choice to diagnose retrocaval ureter. Segmental resection of the ureter with end to end stomosis is the ideal procedure for the treatment of this disease.
