PS-08-016 Can Intracavernosal Botulinum Toxin Injection Salvage Vascular Erectile Dysfunction Patients Not Responding to Oral and Intracavernous Therapy? A Pilot Study
Bibliographic record
Abstract
Evidence has been arising suggesting that Botulinum toxin type A (BTX-A) injections can relax smooth muscles fibers in the treatment of obesity and Detrusor muscle over-activity. We investigate whether a similar effect on cavernosal smooth muscles would help in the treatment of erectile dysfunction (ED) resistant to oral and intracavernous (IC) therapy, thus avoiding surgical treatment options. 24 patients with vascular ED, who failed treatment with non-surgical options, were randomized into 2 equal treatment and control groups. Ethics committee approval and informed consent were obtained. Both groups underwent penile color Doppler evaluation to confirm a vascular etiology. A trimix solution (PGE1 10 ug + Phentolamine 1 mg + Papaverine 30 mg) was injected IC during the penile Doppler study. The treatment group received a single IC injection of BTX-A 50 units 1 day after the penile Doppler/trimix test. The control group received an IC 1 ml saline injection. Assessment for both groups was done by penile color Doppler exam and erection hardness score (EHS) pre-treatment and 2 weeks after treatment. SHIM, and SEP 1 & 2 were completed before treatment and 4 weeks after treatment.

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.
