Bladder's foreign bodies represent an uncommon finding in patients with lower urinary tract symptoms. In most of the cases, patients report themselves the induction of a foreign object into their bladder and it is usually related to altered sexual behavior. These foreign bodies may vary from small everyday objects to larger ones such as catheters or wires. We present a case of a young woman with a history of neurogenic bladder who accidentally misplaced a single-use catheter into her bladder during her self-intermitted catheterization procedure.
A 42-year-old woman presented to the emergency department claiming accidental foreign body insertion into her bladder. The patient had a history of self-intermittent catheterization over the past 10 years due to neurogenic bladder related to multiple sclerosis. She claimed that during her last catheterization she accidentally pushed the catheter inside her urethra because she confounded it with her vagina tampon. The ultrasound evaluation confirmed the foreign body inside her bladder (Figure 1). Eventually, the 12Fr hydrophilic single-use catheter was removed under cystoscopic direct vision, after grasping the tip and pulled out through the urethra (Figure 2).
Foreign bodies inside the bladder are occasionally been reported in the literature [1]. Female urethral anatomy facilitates the insertion of foreign bodies because of the short length and the absence of kinking or prostate obstruction as in males [2]. Numerous foreign bodies including, pen casings, pencils, needles, erotic accessories, small objects, catheters, tampons, swabs and wires have been reported [3]. In most of the cases, the presence of a foreign body is related to masturbation or sexual fetish [4] or psychiatric situations. Iatrogenic misplacement of a part of an instrument or a catheter is also common. The diagnosis can be sometimes tricky, but usually the patients present with macroscopic hematuria, dysuria, urinary tract infection or retention [2]. Rarely, the patients report themselves the transurethral insertion of an object. The management usually includes a transurethral approach to facilitate the object extraction, although there are neglected cases with severe encrustation of the foreign body that may require open surgery [5].
In our case, the patient self-reported the accidental catheter misplacement and the object was effectively retrieved cystoscopically a few hours after the incident with no complications.
