A novel semirigid ureterorenoscope, named the Sotn ureterorenoscope, was designed with a vacuum suction system. The present study aimed to evaluate the feasibility and safety of using the Sotn ureterorenoscope to manage single proximal ureteral or renal pelvic stones.
Data were retrospectively collected from consecutive patients treated with a Sotn ureterorenoscope between February 2010 and August 2015 at Sun Yat-sen Memorial Hospital of Sun Yat-sen University and Jiangmen Wuyi Traditional Chinese Medicine Hospital in China. The primary outcome was the primary stone-free rate (SFR) in 1 month. The secondary outcomes were the final SFR and the perioperative complication rate.
A total of 386 patients were evaluated, including 240 males and 146 females. The median (interquartile range [IR]) age was 50 (40-59) years. There were 96 and 290 stones located in the renal pelvis and proximal ureter, respectively. The median (IR) operative time and console time for all patients were 40 (30-70) and 20 (12-38) minutes, respectively. The primary overall SFR was 86.5%, whereas the SFRs for stones with a diameter of ≤1, 1 to 2, and 2 to 3 cm were 95.7%, 86.9%, and 69.0%, respectively. Complications occurred in 90 patients (23.3%); these complications were classified as Clavien-Dindo grades 1 to 2 (minor) in 79 (20.5%) patients, and grades 3 to 4 (major) in 11 (2.8%).
The novel semirigid Sotn ureterorenoscope featuring a vacuum suction system is effective and safe for managing proximal ureteral and renal pelvic stones.
一种新型半刚性输尿管镜，命名为 Sotn 输尿管镜，配备了真空抽吸系统。本研究旨在评估使用 Sotn 输尿管镜处理单个近端输尿管或肾盂结石的可行性和安全性。
数据来自 2010 年 2 月至 2015 年 8 月在中国中山大学孙逸仙纪念医院和江门市五邑中医院连续接受 Sotn 输尿管镜治疗的患者。主要结局是 1 个月时的主要结石清除率（SFR）。次要结局是最终 SFR 和围手术期并发症发生率。
共评估了 386 例患者，其中 240 例男性，146 例女性。中位（四分位距 [IR]）年龄为 50（40-59）岁。96 例和 290 例结石分别位于肾盂和近端输尿管。所有患者的中位（IR）手术时间和控制台时间分别为 40（30-70）和 20（12-38）分钟。总体主要 SFR 为 86.5%，直径≤1cm、1-2cm 和 2-3cm 的结石 SFR 分别为 95.7%、86.9%和 69.0%。90 例患者发生并发症（23.3%）；这些并发症在 79 例（20.5%）患者中为 Clavien-Dindo 分级 1-2（轻度），在 11 例（2.8%）患者中为 3-4 级（重度）。
配备真空抽吸系统的新型半刚性 Sotn 输尿管镜处理近端输尿管和肾盂结石是有效且安全的。
