Retrocaval ureter with ureteral calculus: Case report.

Retrocaval ureter, which also called circumcaval ureter, is a rare abnormal development where the vena cava compresses the upper segment of ureter leading to different grades of hydronephrosis. We reported a case of a 50-year-old man has a retrocaval ureter with a stone in the loop behind the vena cava. Surgical correction with extraction of the stone was done successfully. On follow up, there was no hydronephrosis. In conclusion synchronized retrocaval ureter with a stone in the ureter is considered a surgical challenge to the urologist and it needs careful investigations to make the diagnosis.
