1965年3月～1982年12月31日作者进行的421次肾移植中,输尿管狭窄的总发生率为5.5％。肾移植后不同时期的发生率分别为:1年为4.6％;2年为7.7％;5年为0.7％,经手术纠正输尿管狭窄后移植肾的存活率在1年和2年为71％,3年为65％。肾移植后输尿管梗阻的发生率,过去报告为2～7.5％,这是根据一个中心进行的肾移植的总数的百分比提出来的。这个数字不确切,确切的发生率应 The total incidence of ureteral stenosis was 5.5% in 421 kidney transplants conducted by the authors between March 1965 and December 31, The incidence rates of renal allografts after transplantation were 4.6% in 1 year, 7.7% in 2 years and 0.7% in 5 years. Survival rate of transplanted kidneys was 71% at 1 year and 2 years after surgical correction of ureteral stricture, 3 years to 65%. The incidence of ureteral obstruction after renal transplantation has been reported in the past to be 2 to 7.5%, as a percentage of the total number of kidney transplants performed in a single center. This number is not exact, the exact incidence should be
