The long-term results (follow-up of 15 months or longer) of antegrade transluminal dilatation of 127 benign ureteral strictures are assessed and analyzed. The overall success rate is 50%. When lesions were classified according to age of the stricture, status of vascular supply, and other etiologic factors contributing to formation, the following findings were evident: transluminal dilatation was successful in 30 (91%) of 33 patients with fresh strictures in whom there was no evidence of compromised vascular supply; in 23 (53%) of 43 similar strictures older than 3 months; in 3 (25%) of 12 with fresh strictures with evidence of vascular compromise; and in 7 (18%) of 39 with similar older strictures. Regardless of age of stricture and other etiologic factors, transluminal dilatation was successful in 53 (70%) of 76 patients with strictures without evidence of ischemic compromise but was successful in only 10 (20%) of 51 with strictures with evidence of devitalization. These findings emphasize the importance of considering both the age and vascular supply of a stricture and adjacent ureter when making the decision about treatment by antegrade transluminal dilatation.
对127例良性输尿管狭窄进行顺行腔内扩张的长期结果（随访15个月或更长时间）进行评估和分析。总体成功率为50%。根据狭窄的年龄、血供状况以及导致狭窄形成的其他病因因素对病变进行分类时，有以下明显发现：33例新鲜狭窄且无血供受损证据的患者中，30例（91%）腔内扩张成功；43例3个月以上类似狭窄的患者中，23例（53%）成功；12例有血供受损证据的新鲜狭窄患者中，3例（25%）成功；39例类似的陈旧性狭窄患者中，7例（18%）成功。无论狭窄的年龄和其他病因因素如何，76例无缺血受损证据的狭窄患者中，53例（70%）腔内扩张成功，但51例有缺血证据的狭窄患者中，仅10例（20%）成功。这些发现强调了在决定采用顺行腔内扩张治疗时，考虑狭窄及相邻输尿管的年龄和血供的重要性。
