Retained Intracavernosal Needle Fragment Following Self-Administered Alprostadil Injection in a Post-Prostatectomy Patient

We report a 69-year-old post-prostatectomy patient who fractured a 30-gauge needle during an intracavernosal injection (ICI) after attempting to straighten it.Migration followed self-extraction attempts.Localized via radiography and ultrasound, the fragment was retrieved through targeted corporotomy under penile block.A literature review of 17 cases identified needle deformation and reuse as primary risk factors.These rare complications are preventable through patient education emphasizing the immediate disposal of compromised needles.Early urological intervention and imaging-guided retrieval ensure successful outcomes, allowing safe resumption of therapy.
