This study retrospectively analyzed the clinical data of four patients with malignant tumor-induced 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.
