Abstract：
Ureteroscopy is a highly effective treatment for ureteral stones, characterized by a high stone-free rate and a low need for re-treatment. Ureteral stent placement can improve the insertion of the ureteral access sheath and ureteroscope but may be associated with higher morbidity prior to and after ureteroscopy. The study aimed to compare immediate versus post-stenting ureteroscopy for ureteral stone treatment in terms of operative time, intra- and post-operative complications, length of hospital stay, and stone-free rate. This prospective study involved 126 patients with ureteral stones divided into two groups: the post-stenting ureteroscopy group (PS-URS), who underwent primary ureteral stenting by double J followed by delayed ureteroscopy, and the immediate ureteroscopy group (I-URS), who underwent immediate ureteroscopy without previous stenting. Sixty-six patients were included in the PS-URS group and 60 patients in the I-URS group. Results were comparable, with no significant differences between both groups. The mean operative time was 33.77±3.51 minutes for the PS-URS group and 34.60±2.01 minutes for the I-URS group. The average length of hospital stay was 0.84±2.55 days for PS-URS and 0.92±1.96 days for I-URS patients. The stone-free rate was 97% in the PS-URS group and 95% in the I-URS group. The overall complication rate was 4.5% versus 5% in the PS-URS and I-URS groups, respectively, with all complications being minor and managed effectively. Immediate ureteroscopy is a safe and relevant operative approach for ureteral stones, with comparative results for post-stenting delayed ureteroscopy.
摘要：
输尿管镜检查是一种非常有效的治疗输尿管结石，其特点是无结石率高，需要再治疗。输尿管支架放置可以改善输尿管入路鞘和输尿管镜的插入，但在输尿管镜检查之前和之后可能会导致更高的发病率。该研究的目的是在手术时间方面比较即刻与支架置入后输尿管镜检查治疗输尿管结石。术中和术后并发症，住院时间,和无石价。这项前瞻性研究涉及126例输尿管结石患者，分为两组：支架置入后输尿管镜组（PS-URS），接受双J输尿管支架置入术，然后延迟输尿管镜检查，输尿管镜组（I-URS），在没有植入支架的情况下立即接受了输尿管镜检查。PS-URS组包括66例患者，I-URS组包括60例患者。结果具有可比性，两组之间没有显着差异。PS-URS组的平均手术时间为33.77±3.51分钟，I-URS组为34.60±2.01分钟。PS-URS患者的平均住院时间为0.84±2.55天，I-URS患者的平均住院时间为0.92±1.96天。PS-URS组无结石率为97%,I-URS组无结石率为95%。PS-URS组和I-URS组的总并发症发生率为4.5%与5%,分别,所有并发症都是轻微的，并得到有效管理。即时输尿管镜检查是治疗输尿管结石的安全且相关的手术方法，与支架置入后延迟输尿管镜检查的比较结果。
