Abstract
Self-inflicted foreign bodies in the urinary bladder are very rarely reported. Insertion of a wide
variety of objects into bladder due to autoerotic stimulation, psychiatric disturbances, and
senility etc. have been reported in the medical literature. This case report discusses an
exceptional incident where a young male patient self-inserted a ball-point pen into his urinary
bladder via the urethra. Notably, the pen negotiated the curvatures of the urethra without
causing significant lower urinary tract injury. The report underscores the challenges and
successful endoscopic removal of the pen, marking the first documented instance of such an
extraction in a male patient.
