This study was designed to test the hypothesis that high urinary output in patients with an indwelling bladder catheter tends to protect the patients from acute urinary tract infection. Thirty-five cases of acute spinal cord injury were analyzed for average daily urine volume and frequency of acute urinary infection (defined as oral temperature above 101 F and requiring treatment for the infection). The study period encompassed the time from entry into the Rehabilitation Unit until a definitive effort was made to remove the catheter, a mean of 59 days. Twenty-six patients developed acute urinary infections while nine did not. Mean 24-hour urine output in the two groups was 2530 cc and 2540 cc, respectively. The only difference which could be found was a significant decrease in urinary output in the symptomatic group during the seven days preceding onset of acute infection.
留置膀胱导管患者的高尿量倾向于保护患者免受急性尿路感染。分析了35例急性脊髓损伤患者的平均每日尿量和急性尿路感染频率（定义为口腔温度高于101华氏度且需要治疗感染）。研究期涵盖从进入康复单元到最终努力拔除导管的时间，平均为59天。26例患者发生急性尿路感染，而9例未发生。两组的平均24小时尿量分别为2530毫升和2540毫升。唯一能发现的差异是有症状组在急性感染发作前七天尿量显著减少。
