During a 11-year period 21 toilet-trained, prepubertal boys were seen with blood spotting on the undershorts (urethrorrhagia) between voidings. Most patients presented in the winter and spring months as opposed to the summer and fall months. The median age at presentation was 7 years. The most frequent presenting system, in addition to urethrorrhagia, was dysuria. Laboratory and radiographic studies were frequently normal, although red blood cells were seen microscopically in 57 per cent. Bacterial cultures were always negative. Symptoms persisted for as long as 8 years (median between 6 and 12 months). The etiology of this symptom complex in these cases is unknown but is thought to be an infectious agent. Strictures developed in 3 patients, all of whom had had prior endoscopy. In none of the 6 patients in whom cystoscopy was omitted did a stricture develop. Inasmuch as endoscopy is unnecessary to rule out serious lesions that might mimic idiopathic urethrorrhagia, its use on a routine basis in these patients does not seem warranted.
在11年的时间里，我们观察到21名已完成如厕训练的青春期前男孩在排尿间隙出现短裤上有血迹（尿道出血）的情况。大多数患者在冬季和春季就诊，而非夏季和秋季。就诊时的中位年龄为7岁。除尿道出血外，最常见的症状是排尿困难。实验室和影像学检查通常正常，不过显微镜下可见红细胞的情况占57%。细菌培养结果始终为阴性。症状持续长达8年（中位时间为6至12个月）。这些病例中这种症状复合体的病因尚不清楚，但被认为是一种感染因子。3名患者出现了尿道狭窄，他们都曾接受过内镜检查。在未进行膀胱镜检查的6名患者中，无一例出现尿道狭窄。鉴于排除可能模拟特发性尿道出血的严重病变无需进行内镜检查，因此在这些患者中常规使用内镜似乎并无必要。
