The presence of a foreign body resembling a worm in a urine collection bag should lead to etiological investigation, as it may not be a parasite. It is thus important to consider the context and origin of the patient, together with the size, length, appearance, and characteristics of the suspected worm.
The presence of an apparently mobile black filament resembling a worm was reported in the urine collection bag of a 77-year-old African male resident of our long-term care facility. We initially suspected a parasitic infection. The description of this foreign body suggested Dioctophyma renale (giant kidney worm); however, the analysis of the sample concluded that it was a blood clot. Its worm-like appearance was due to the tube-like nature of the urethra, causing the blood clot to be squeezed into a worm-like shape.
Such presentations can be misleading and may lead to unnecessary concern and investigations. A parasitological analysis can be essential for precise diagnosis.
在尿液收集袋中出现类似蠕虫的异物时，应进行病因调查，因为它可能并非寄生虫。因此，结合患者的背景和来源，以及疑似蠕虫的大小、长度、外观和特征进行综合考虑非常重要。
在我们长期护理机构的一名77岁非洲男性居民的尿液收集袋中，发现了一条看似可移动的黑色丝状类似蠕虫的物体。我们最初怀疑是寄生虫感染。对该异物的描述提示为肾膨结线虫（巨型肾虫）；然而，样本分析得出结论，它是一个血凝块。其蠕虫样外观是由于尿道的管状结构，导致血凝块被挤压成蠕虫状。
此类表现可能具有误导性，可能导致不必要的担忧和检查。寄生虫学分析对于准确诊断可能至关重要。
