To evaluate the clinical outcomes with a Chinese single-use fiberoptic flexible ureteroscope (YouCare Tech) from a prospective database.
A prospective study was conducted in a single center in China between January 2016 and October 2017. All consecutive patients who underwent flexible ureteroscopy performed by YouCare flexible ureteroscope were analyzed. Patients' demographics, clinical characteristics, intraoperative parameters, postoperative complications, and stone-free rate were evaluated and recorded. Stone-free status was defined as no visible stones or clinically insignificant residual stones < 2 mm on a postoperative image study.
A total of 684 procedures were performed for 653 patients (31 patients had bilateral stones). A double J stent had been previously placed in 431 patients. The location of the calculi was upper calyx, middle calyx, lower calyx, and renal pelvis and proximal ureter in 74, 101, 211, 115, and 183 patients, respectively. The median operative time was 52 min. The postoperative stone-free rate for the first 2 weeks after surgery was 78.5%, which increased to 91.1% at the first month. The overall stone-free rate was 95.2%. The complication rate was minor and short-term, such as gross hematuria or flank pain.
YouCare flexible ureteroscope can be considered effective and safe in the treatment of both upper ureteral and renal stones in selected patients. Further evaluation of comparison with other FURS's surgical outcomes and cost-effectiveness analysis will help to present the best utility of this single-use FURS in clinical practice.
通过前瞻性数据库评估中国产一次性使用的可弯曲光纤输尿管镜（佑康医疗科技）的临床疗效。
2016年1月至2017年10月在中国的一个中心进行了一项前瞻性研究。对所有连续接受佑康可弯曲输尿管镜进行输尿管镜检查的患者进行分析。评估并记录患者的人口统计学资料、临床特征、术中参数、术后并发症和无石率。无石状态定义为术后影像学检查未见明显结石或残留结石<2mm且临床意义不大。
共对653例患者（31例患者为双侧结石）进行了684例手术。431例患者此前已置入双J支架。结石位于上盏、中盏、下盏、肾盂和输尿管上段的患者分别为74例、101例、211例、115例和183例。中位手术时间为52分钟。术后前2周的无石率为78.5%，第1个月时升至91.1%。总体无石率为95.2%。并发症发生率较低且为短期，如肉眼血尿或腰痛。
对于部分患者，佑康可弯曲输尿管镜在治疗输尿管上段和肾结石方面可被认为是有效且安全的。与其他软性输尿管肾镜手术结果的进一步比较评估和成本效益分析将有助于展现这种一次性使用软性输尿管肾镜在临床实践中的最佳效用。
