The aim of this study was to investigate the effect of placing double J (D-J) stents using high-pressure balloon angioplasty in treating benign ureteral stricture.Methods A total of 42 patients (48 cases) with benign ureteral stricture (42 had benign ureteral stricture) were investigated by inserting dual D-J stents using high-pressure balloon angioplasty. The control group contained 50 patients (57 cases) employing the conventional balloon angioplasty with a single D-J stent inserted for comparison.Results The overall effective rate of the treated and control groups was 87.8% (36/41) and 62.7% (32/51), respectively (P 〈0.05).Conclusion This new approach produces a better curative effect than the conventional balloon angioplasty with a single D-J stent insertion in treating benign ureteral stricture.展开更多
目的探讨输尿管镜球囊扩张术治疗良性输尿管狭窄(US)的临床效果。方法回顾性分析输尿管镜下球囊扩张治疗18例US患者资料。男8例,女10例,年龄21~73岁,平均42岁。其中狭窄17例,闭锁1例。窄段长度〈0.5 cm 10例,0.5~1.5 cm 6例,1.5 cm以...目的探讨输尿管镜球囊扩张术治疗良性输尿管狭窄(US)的临床效果。方法回顾性分析输尿管镜下球囊扩张治疗18例US患者资料。男8例,女10例,年龄21~73岁,平均42岁。其中狭窄17例,闭锁1例。窄段长度〈0.5 cm 10例,0.5~1.5 cm 6例,1.5 cm以上2例。狭窄段位于肾盂输尿管连接部3例,上段4例,中段4例,下段7例。结果 18例患者均在输尿管镜引导下找到正确通道,完成球囊扩张手术。留置单条7F输尿管内支架管10例,留置双条5F输尿管支架管8例。17例留置双J管6~12个月,1例患者留置双J管3个月。术后随访12~36个月,10例一次手术扩张有效。6例拔管半年后再次狭窄,行二次球囊扩张后有效。2例输尿管肾盂的接合处(UPJ)狭窄段过长,肾滤过功能均小于20 ml/min,术后1年复查,再次狭窄,行后腹腔镜下UPJ整形术后有效。结论输尿管镜球囊扩张术是治疗US安全、有效的手术方法,可以作为US长度在1.5 cm以内的单侧肾功能轻-中度损害的US的首选方案。展开更多
目的探讨两种不同扩张输尿管的方法在输尿管下段狭窄治疗中的效果。方法回顾性研究分析2010~2017年收治的36例输尿管下段狭窄合并输尿管中下段结石,在做输尿管镜下碎石时发现输尿管狭窄,分别采取直视下输尿管钳撑开缓慢扩张法和球囊扩...目的探讨两种不同扩张输尿管的方法在输尿管下段狭窄治疗中的效果。方法回顾性研究分析2010~2017年收治的36例输尿管下段狭窄合并输尿管中下段结石,在做输尿管镜下碎石时发现输尿管狭窄,分别采取直视下输尿管钳撑开缓慢扩张法和球囊扩张法。其中男20例,女16例。年龄20~71岁,平均45岁。输尿管下段结石者22例,输尿管中段结石者14例,结石最大径为6~20 mm,平均11 mm,患侧肾功能轻度受损者6例,中度受损者27例,重度受损者3例。术中均用Wolf F 8/9.8输尿管镜入镜失败。将患者随机分成两组,A组19例,运用直视下输尿管钳撑开缓慢扩张法扩张输尿管;B组17例,运用球囊扩张法扩张输尿管,最终两组经过扩张后均能顺利入镜并碎石成功。留置双J管6周后反院拔管并入镜输尿管下段镜检狭窄情况。结果两组扩张对输尿管均有不同程度损伤,轻度损伤如粘膜撕裂A组高于B组,较重输尿管损伤如肌层撕裂、输尿管穿孔A组偏低。A组手术时间短于B组,术中出血及术后疼痛情况两组比较差异无统计学意义(P>0.05)。6周后输尿管镜检均能顺利入镜,穿孔位置黏膜光滑。结论两种扩张输尿管方法均可安全有效的治疗输尿管下段狭窄,为输尿管结石腔内碎石提供保障,其中输尿管钳缓慢扩张法是在直视下缓慢进行的,相对球囊非直视下扩张引起输尿管撕裂、穿孔几率小,并且费用低廉,适合基层医院开展,为输尿管狭窄合并输尿管结石患者提供新的有效治疗方法。展开更多
