Residual urine following catheterization was studied using ultrasonography (Ultramark II Scientific Medical System) in 12 patients with spinal cord injury, for an average of four months (range 3-7 months) after time of injury. All patients were examined three times. Urinary tract infections were also registered, and the functional type of the urinary bladder was identified by cystometric examination. Ultrasonography showed residual urine volumes after 25 of a total of 36 catheterizations (70%). In seven of these catheterizations the residual urine volume exceeded 50 ml, and in two cases was more than 100 ml. None of the patients had a residual urinary volume of more than 50 ml after all three catheterizations, but in all but two patients, some residual urine volume was found after at least one of the catheterizations. Low and non-significant correlations were found between residual volume and frequency of urinary tract infections. It is possible that even small residual urine volumes after catheterization may predispose for urinary tract infections in these patients.
采用超声检查（Ultramark II 科学医疗系统）对 12 例脊髓损伤患者导尿后的残余尿量进行了研究，这些患者在受伤后平均四个月（范围为 3 - 7 个月）接受检查。所有患者均接受了三次检查。还记录了尿路感染情况，并通过膀胱测压检查确定膀胱的功能类型。超声检查显示，在总共 36 次导尿中有 25 次（70%）存在残余尿量。在其中 7 次导尿中，残余尿量超过 50 ml，2 例超过 100 ml。所有三次导尿后均无患者残余尿量超过 50 ml，但除 2 例患者外，所有患者至少在一次导尿后发现有一些残余尿量。残余尿量与尿路感染频率之间存在低且无统计学意义的相关性。导尿后即使残余尿量很少也可能使这些患者易患尿路感染。
