Abstract
INTRODUCTION: Men with nonpalpable isolated septal scars (ISS) identified with color duplex ultrasonography (CDU) comprise a group of previously unrecognized patients with wide-ranging sexual concerns. AIM: We aim to identify the clinical characteristics of patients presenting with this atypical form of Peyronie's disease characterized by the absence of palpable deformity. MATERIALS AND METHODS: Of 482 consecutive patients who presented to a tertiary care erectile dysfunction (ED) clinic and underwent CDU after satisfying inclusion criteria, 27 (5.6%) men with nonpalpable ISS and no dorsal or ventral plaque were identified. MAIN OUTCOME MEASURES: International Index of Erectile Function (IIEF), CDU, and clinical characteristics. RESULTS: The median age of the men with nonpalpable ISS was 49 years. The length of time from onset of symptoms to presentation was 22 months, and the pretreatment IIEF score was 14. The remaining 455 men who underwent CDU were of similar age (48 years) but had a markedly lower IIEF score of 9.5 (statistical median). ISS patients presented with decreased penile rigidity (20), penile shortening (13), chronic pain with erection (13; mean 33 months), and the inability to maintain an erection (7). Fourteen men had failed phosphodiesterase-5 inhibitor therapy, and four reported unsatisfactory results. Management options included retrial with oral agents, intracavernous pharmacotherapy, verapamil injections, and surgery. CONCLUSIONS: The clinician should be suspicious for nonpalpable ISS in men with sexual concerns who present with decreased penile rigidity, length loss, and chronic pain with erection. Our findings support the use of CDU for this patient group, particularly when previous treatment has failed, because men with ISS had a greater likelihood of having no palpable deformity or curvature and ongoing penile pain.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
