1·Objective To explore the etiology, classification, differential, diagnosis and treatment of ureteric polyps.
目的对输尿管息肉的病因、分类、诊断及治疗进行探讨。
2·Conclusions: MPCNL is a therapeutic modality with advantages of high achievement ratio and slight injury especially for upper ureteric calculus with narrow ureter and ureter twist.
结论：MPCNL治疗输尿管上段结石，取石成功率高，创伤小，尤其在输尿管上段结石并发狭窄、扭曲时有良好的疗效。
3·Conclusion Ureteroscopy for removing uncomplicated distal calculi is safe with no stent after treatment and routine use of ureteric stents is unnecessary.
结论经输尿管镜治疗单纯输尿管下段结石常规放置输尿管支架管是不必要的。
4·Results: At 18th day of incubation, ureteric bud from cloaca grew into metanephrogenic tissue which produced many metanephrogenic vesicles.
结果：孵育第18天，从泄殖腔附近发出的输尿管芽向生后肾组织侵入生长，生后肾组织产生许多生后肾小泡。
5·Methods: Nonenhanced CT and 3D reconstruction images of 20 patients with acute ureteric calculi were analyzed retrospectively.
方法：对20例急性输尿管结石患者的螺旋CT平扫及三维立体重建图像表现进行分析。
