A retrospective analysis of 136 patients, who were submitted rigid ureteroscopy for stone removal, was performed. Patients were divided into two groups. First group consisted of 63 patients with routine balloon dilation of intramural part of ureter before ureteroscopy. 73 patients of the second group were submitted ureteroscopy without previous ureter dilation. The total success rate was achieved in the first and second group of the patients in 90.5% and 91.8%. The success rate achieved in removing of the stone of upper, middle and lower part of the ureter was in the first group 81.8%, 88.9% and 94.1% and in the second group 78.6%, 95%, 94.9%, respectively. None of the patients have demonstrated vesico-renal reflux. With respect to our similar success rate in both of the groups they don't consider routine dilation of ureter as necessary before ureteroscopy.
对136例行硬性输尿管镜取石术的患者进行了回顾性分析。患者分为两组。第一组由63例在输尿管镜检查前对输尿管壁内部进行常规球囊扩张的患者组成。第二组的73例患者未进行输尿管扩张就接受了输尿管镜检查。第一组和第二组患者的总成功率分别为90.5%和91.8%。第一组输尿管上、中、下段结石的清除成功率分别为81.8%、88.9%和94.1%，第二组分别为78.6%、95%、94.9%。所有患者均未出现膀胱肾反流。鉴于两组的成功率相似，他们认为输尿管镜检查前没有必要常规扩张输尿管。
