Antistress toy as a foreign body in the urinary bladder: a case report

Background: Intravesical foreign bodies are rare and are often associated with psychiatric disorders or paraphilic behaviors. They can cause pain, hematuria, infection, and urinary retention. Recurrent cases pose particular diagnostic and therapeutic challenges. Case presentation: A 36-year-old male presented after self-inserting a rectangular antistress elastic cord through the urethra into the bladder, causing severe pelvic pain and gross hematuria. His history included two prior cystoscopies for similar events. Computed tomography revealed a 14 cm spiked foreign body. Open midline cystotomy allowed complete removal without complications. Psychiatric evaluation revealed a paraphilic disorder, and a multidisciplinary follow-up plan was initiated. Conclusion: This recurrent and unusual case underscores the importance of individualized surgical planning, particularly for large or irregular foreign bodies, and highlights the necessity of psychiatric assessment to prevent recurrence. Multidisciplinary care is strongly recommended. Trial registration This study does not report results of a clinical trial.
