The origin of vesical and lower urinary tract foreign bodies is very wide, the specialized literature descriptions ranging from urethral dilators to coffee spoons handles through wires, cables and surgical instrumentation. The most frequent entry route of foreign bodies to the lower urinary tract is through the urethra usually by self-introduction or during transurethral surgical procedures. Another access route is that occurring during open or traumatic surgical manoeuvres. Less frequent is that the foreign body migrates from another anatomical structure. These patients present an heterogeneous clinical picture which depends on the location of the foreign body in the urinary tract. Thus, it can be acute if located in the urethra or subacute or chronic if found at vesical level.
膀胱及下尿路异物的来源非常广泛，专业文献描述的异物种类繁多，从尿道扩张器到咖啡匙柄，还有电线、电缆及外科器械等。异物进入下尿路最常见的途径是经尿道，通常是自行置入或在经尿道手术过程中。另一种进入途径是在开放性或创伤性手术操作期间发生。异物从另一个解剖结构迁移过来的情况较少见。这些患者呈现出异质性的临床表现，这取决于异物在尿路中的位置。因此，如果位于尿道，可能是急性的；如果在膀胱水平发现，则可能是亚急性或慢性的。
