During a program of intermittent catheterization and bladder retraining, patients were taught new voiding techniques to reduce residual urine volumes gradually. Results were taught new voiding techniques to reduce residual urine volumes gradually. Results of urine cultures done weekly were recorded. Data from 105 patients during 1,190 patient-weeks were analyzed to determine if residual urine volumes correlated with rates of urinary tract infection. Mean and median residual urine volumes were 192 ml and 176ml, respectively, for positive culture results and 159ml and 138ml, respectively, for negative results (p less than 0.01). A progressive increase in the rate of urinary tract infection was apparent between residual urine volumes of 100ml and 250ml. The rate decreased unexpectedly for residual volumes greater than 250ml; the explanation requires an additional antimicrobial mechanism.
在间歇性导尿和膀胱再训练计划期间，患者学习了新的排尿技巧以逐渐减少残余尿量。记录每周进行的尿培养结果。分析了105例患者在1190个患者周的数据，以确定残余尿量是否与尿路感染率相关。培养结果为阳性时，平均和中位数残余尿量分别为192毫升和176毫升；培养结果为阴性时，分别为159毫升和138毫升（p小于0.01）。残余尿量在100毫升至250毫升之间时，尿路感染率明显呈逐步上升趋势。残余尿量大于250毫升时，感染率意外下降；对此的解释需要另一种抗菌机制。
