实时超声引导经尿道输尿管镜金属支架置入治疗恶性肿瘤致输尿管梗阻的应用体会

Application of real-time ultrasound-guided transurethral ureteroscopic metal stent placement to trea ureteral obstructioncaused by malignant tumor

本研究回顾性分析我院收治的4例恶性肿瘤致输尿管狭窄患者的临床资料。所有患者均在实时超声引导下顺利完成经输尿管镜金属支架置入术,手术时间(64±33)min。术后患者肌酐下降(74±127)mmol/L。术后仅2例发生Clavien-DindoI级并发症。所有患者支架管位置良好,术后住院时间(2.5±0.6)d。本手术方法对于恶性肿瘤引起的输尿管梗阻,可以弥补内镜视野的不足。

This study retrospectively analyzed the clinical data of four patients with malignant tumorinduced ureteral strictures admitted to our hospital.All patients successfully underwent ureteroscopic metal stent placement surgery under real-time ultrasound guidance,with a surgical duration of(64±33)minutes.Postoperatively,there was a creatinine decrease of(74±127)mmol/L.Only two cases experienced Clavien-Dindo grade I complications postoperatively.The stents were well positioned in all patients,with a postoperative hospital stay of(2.5±0.6)days.This surgical approach for malignant tumor-induced ureteral obstruction can compensate for the limitations of endoscopic visualization.
