[Retrocaval ureter - diagnosis and surgical management].

There are presented 6 cases of retrocaval ureter treated by the reconstructive surgical intervention, with good results in 5 cases and bad results in 1 case. Characteristic statement on intravenous pyelography and retrograde ureteropyelography is enough for diagnosis of retrocaval ureter; if it is not characteristical, but the doubt exists on retrocaval ureter, the cavography is necessary. In the presence of hydronephrosis, the early operative reposition of ureter (pyeloureter, ureter-ureter, vena cava, vena cava anastomosis) is most important because it saves the residual function of kidney.
