A Broken Intracavernous Needle: Successful Ultrasound-Guided Removal
Bibliographic record
Abstract
INTRODUCTION: Common complications of intracavernous injection therapy include pain, hematoma formation, syncope, prolonged erections, and penile fibrosis. Rare reported complications include postinjection cavernositis, intracorporeal needle breakage. AIM: We report a case of postinjection intracavernous needle breakage with successful ultrasound-guided retrieval. METHODS: A 32-year-old patient complaining of a 6-month penile pain following intracavernous papaverine injection presented to our department. Clinical examination and penile ultrasound revealed a broken intracavernous needle at the left mid-dorsum aspect of the penis with surrounding fibrosis. A decision was made to remove the broken needle. RESULTS: The needle was dislodged effortlessly under local anesthesia. CONCLUSION: A deeply seated intracavernous broken needle should be immediately retrieved. Patients must be carefully instructed on the proper injection technique with emphasis on the delicacy of the needle and the possibility of needle breakage during injection.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
