One hundred patients, aged twenty to ninety-two years, underwent 111 procedures for removal of bladder calculi. Most patients (88) had some type of bladder outlet obstruction. Two types of stones were identified: those that had apparently formed in the upper tract and been trapped in the bladder (17 cases) and those that appeared to have formed in the bladder in the presence of various types of outlet obstruction. Stone analysis revealed uric acid stones in 50 percent, calcium oxalate stones in 19 percent, and stones of mixed composition in 31 percent. Five patients had metabolic abnormalities predisposing to stone formation; in 2 cases, these abnormalities were discovered during the evaluation for stone disease. Treatment depended on stone characteristics, associated pathology, and the general health of the patient. A review of the literature with regard to the morbidity and mortality of combining treatment of vesical calculi and bladder outlet obstruction secondary to prostatic obstruction is included.
100名年龄在20岁至92岁之间的患者接受了111次膀胱结石清除手术。大多数患者（88名）存在某种类型的膀胱出口梗阻。识别出两种类型的结石：明显在上尿路形成并被困在膀胱中的结石（17例）以及在存在各种类型出口梗阻的情况下似乎在膀胱中形成的结石。结石分析显示，尿酸结石占50%，草酸钙结石占19%，混合成分结石占31%。5名患者有易导致结石形成的代谢异常；其中2例是在对结石病进行评估时发现这些异常的。治疗取决于结石特征、相关病理情况以及患者的总体健康状况。本文还纳入了关于合并治疗膀胱结石和前列腺梗阻继发的膀胱出口梗阻的发病率和死亡率的文献综述。
