Abstract

Background: To evaluate the clinical application value of tip-flexible suctioning ureteral access sheath (TFS-UAS), this study compares the efficacy and safety of TFS-UAS versus traditional ureteral access sheath (T-UAS) in treating unilateral renal or proximal ureteral calculi, and further summarizes the usage strategy of TFS-UAS by synthesizing vitro experiment and surgical best practices.

Methods: A retrospective analysis was conducted on 196 patients with renal or proximal ureteral calculi treated with FURS and holmium laser lithotripsy at Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. Patients were divided into TFS-UAS and T-UAS groups. Primary data included operative time, immediate SFR (iSFR), and 2-week SFR. Secondary data encompassed changes in blood parameters (leukocytes, hemoglobin, urea nitrogen, creatinine), complications, and hospital stay.

Results: This retrospective study found that urologists preferred to use TFS-UAS for larger (17.73 ± 7.79 mm vs. 12.56 ± 5.14 mm, P < 0.001), harder (1156.52 ± 420.15 vs. 778.39 ± 513.46 Hounsfield units, P < 0.001), and more complex (modified STONE score: 10.86 ± 2.51 vs. 7.37 ± 2.28, P < 0.001) upper urinary tract calculi. No significant differences in operative time or SFR were found between the TFS-UAS and T-UAS groups overall. However, for stones ≥ 15 mm, those that were larger(22.57 ± 6.35 mm vs. 18.70 ± 3.82 mm, P = 0.001), harder(1160.76 ± 382.84 vs. 896.56 ± 465.33, P = 0.007), and more complex(modified STONE score: 11.43 ± 2.40 vs. 8.63 ± 2.31, P < 0.001), TFS-UAS significantly reduced operative time (53.92 ± 21.77 vs. 65.76 ± 22.43 min, P < 0.001) and improved iSFR(91.89% vs. 73.17%, P = 0.063), 2-week SFR(81.08% vs. 56.10%, P = 0.018).

Conclusions: TFS-UAS combined with FURS significantly improves operative efficiency and SFRs for upper urinary tract calculi ≥ 15 mm, demonstrating clinical advantages.

尖端柔性吸引输尿管通路鞘联合柔性输尿管镜：包括体外实验在内的单机构经验。

背景：为评价尖端柔性抽吸输尿管导管鞘（TFS-UAS）的临床应用价值，本研究比较TFS-UAS与传统输尿管导管鞘（T-UAS）治疗单侧肾或输尿管近端结石的疗效和安全性，并综合体外实验和手术最佳实践，进一步总结TFS-UAS的使用策略。方法：回顾性分析上海中医药大学附属阳光医院钬激光碎石术治疗肾结石或输尿管近端结石196例。患者分为TFS-UAS组和T-UAS组。主要数据包括手术时间、即时SFR （iSFR）和2周SFR。次要数据包括血液参数（白细胞、血红蛋白、尿素氮、肌酐）、并发症和住院时间的变化。结果：本回顾性研究发现，对于较大（17.73±7.79 mm vs. 12.56±5.14 mm）的上尿路结石，泌尿科医师更倾向于使用TFS-UAS， P。结论：TFS-UAS联合FURS可显著提高上尿路结石≥15 mm的手术效率和SFRs，具有临床优势。
