Seventy-six nursing home residents with urinary incontinence (59 females, 17 males, Mean age = 84 years) underwent an evaluation which included the measurement of residual urine and cystometric studies. Upon catheterization 18 subjects were found to have urine volumes greater than 100 ml. Only two subjects had urine volumes greater than 250 ml. Cystometry revealed detrusor instability in the majority (83%) of the 76 subjects. Although the measurement of the post-voiding residual urine is a simple method to assess for ineffective bladder emptying, at volumes less than 250 ml, it is not always possible to predict the type of bladder dysfunction without additional studies. There can be problems in obtaining an accurate measurement of the post-voiding residual urine in elderly institutionalized patients. Many of our subjects (36 subjects) experienced difficulty urinating prior to catheterization. The residual urine measurement should not be solely relied upon in the prediction of bladder dysfunction in the elderly. This measurement should be combined with other data to effectively investigate the etiology of urinary incontinence.
76名患有尿失禁的养老院居民（59名女性，17名男性，平均年龄84岁）接受了一项评估，其中包括残余尿量测量和膀胱测压研究。导尿时发现18名受试者的尿量超过100毫升。只有两名受试者的尿量超过250毫升。膀胱测压显示76名受试者中的大多数（83%）存在逼尿肌不稳定。尽管排尿后残余尿量的测量是评估膀胱排空无效的一种简单方法，但当尿量小于250毫升时，若无其他检查，往往无法预测膀胱功能障碍的类型。在老年住院患者中，准确测量排尿后残余尿量可能存在问题。我们的许多受试者（36名受试者）在导尿前排尿困难。在预测老年人膀胱功能障碍时，不应仅依赖残余尿量测量。该测量应与其他数据相结合，以有效探究尿失禁的病因。
