Three hundred and sixteen patients with ureteral stones were treated in situ (without retrograde stone manipulation) with and without stent bypass (DJ stent, ureteral catheter). Results were generally better with stent bypass, but only marginally so for stones larger than 10 mm in diameter. Regardless of whether or not the ureter was stented, lower ureteral stones were more difficult to fragment than upper ureteral stones and pre-sacral stones did not respond well to in situ treatment. We observed that evaluation of stone disintegration and fragment evacuation could only be properly assessed after approximately 3 weeks post-ESWL.
316例输尿管结石患者接受了原位治疗（未进行逆行结石操作），部分患者使用了支架旁路（DJ支架、输尿管导管），部分未使用。总体而言，使用支架旁路的治疗效果更好，但对于直径大于10mm的结石，效果仅略好。无论输尿管是否置入支架，下段输尿管结石比上段输尿管结石更难碎石，骶前结石对原位治疗反应不佳。我们观察到，体外冲击波碎石（ESWL）后约3周才能准确评估结石碎裂和碎片排出情况。
