The authors report about 12 cases of long ureteral calculi, 16 to 39 mm in size, observed over 10 years. They were all made of a mixture of ammonium-magnesium phosphate and calcium phosphocarbonate. Infection was the revealing symptom, either in the form of simple bacteriuria or as acute pyelonephritis or sepsis. These calculi, found in a lumbar or pelvic location, were very long, radiopaque but with a moderate radiological density, homogeneous and have regular contours. They were straight, sometimes slightly bent, rarely (one case out of 12) arciform. In 11 of 12 cases, the affected patient was female. In most cases, the urine was infected by Proteus mirabilis. In spite of their size, the calculi caused total obstruction in 3 of 12 cases only. They were or were not associated to ipsilateral coral calculi of the same chemical type. Destruction was easily achieved with physical agents. The etiological, radiological and therapeutic characteristics of these calculi give them a specific place among ammonium-magnesium phosphate calculi.
作者报告了10年间观察到的12例长输尿管结石病例，结石大小为16至39毫米。它们均由磷酸铵镁和磷酸碳酸钙混合而成。感染是首发症状，表现为单纯菌尿、急性肾盂肾炎或败血症。这些结石位于腰部或盆腔，很长，不透射线但放射密度中等，质地均匀且轮廓规则。它们是直的，有时略有弯曲，很少（12例中有1例）呈弧形。12例中有11例患者为女性。多数情况下，尿液由奇异变形杆菌感染。尽管结石较大，但12例中仅3例导致完全梗阻。它们与同侧相同化学类型的鹿角状结石有关或无关。用物理方法很容易实现碎石。这些结石的病因、放射学和治疗特征使其在磷酸铵镁结石中占有特殊地位。
