Objective:To analyze the cause and treatment of ureteral stenosis in the early stage after kidney transplantation.Methods:250 cases of the kidney transplantation since 1993 to 2007 were collected and analyzed

including 141 men and 109 women

240 cadaveric transplantations and 10 living dononr transplantations. Results:In 8 cases(3.2%) ureteral stenosis occurred in the early stage following the renal transplantation;including hematoma compression(2cases);stenosis of ureter- bladder stoma(2cases);ureter torsion(1case);transplantal kidney torsion(1case);stomal leak(1case) and hydropsia of spermatic cord(1case). 7 cases required another surgical operation to remove the obstruction and the renal function recovered in these cases. Conclusion:The ureteral stenosis in the early stage of kidney transplantation was mostly contributed to the surgical reasons such as mis-perfamance. The occurance rate of ureteral stenosis should be reduced if each one step of the kidney transplantation is carefully performed. The open surgical managemen is a direct and effective method to remove the obstruction.
