During the past seven years, 14 pregnant patients were admitted to our hospital for treatment of ureteral calculus. During this same period, 22,495 deliveries were performed, for an incidence of one calculus per 1,600 pregnancies. Eleven patients spontaneously passed the calculus, ten prior to delivery and one patient postpartum. Three patients required an operation, two antepartum and one patient postpartum. No maternal or fetal complications occurred. Management of urinary calculi during pregnancy must be individualized and should be based upon location of the stone, degree of obstruction, presence or absence of infection, general condition of the patient and stage of pregnancy. Surgical intervention to remove obstructing calculi is not contraindicated during pregnancy.
在过去七年中，有14名怀孕患者因输尿管结石入院治疗。在同一时期，共进行了22495例分娩，结石发病率为每1600次怀孕中有1例。11名患者结石自然排出，其中10名在分娩前，1名在产后。3名患者需要手术，2名在产前，1名在产后。未发生母婴并发症。孕期尿路结石的处理必须个体化，应根据结石位置、梗阻程度、有无感染、患者一般情况及孕周来决定。孕期进行手术干预以取出梗阻性结石并非禁忌。
