Abstract
PURPOSE: The post-vasectomy pain syndrome is a rare but serious and debilitating complication of vasectomy. For men with the post-vasectomy pain syndrome vasectomy reversal is a surgical option after medical management has failed. However, there is a paucity of data in the literature defining its therapeutic efficacy. In this study we better define the role and effect of vasectomy reversal in the treatment of men with the post-vasectomy pain syndrome. MATERIALS AND METHODS: Three urologists in Toronto, Ontario performed 149 publically funded vasectomy reversals between January 2000 and September 2010. The electronic health records were reviewed and 23 of the 149 (15%) procedures were performed for the post-vasectomy pain syndrome. Of these men who underwent 14 vasovasostomies 13 completed a telephone conducted questionnaire (response rate 56%). Patient demographics, preoperative and postoperative pain scores, and quality of life were retrospectively assessed. RESULTS: Orchialgia occurred a mean ± SD of 19 ± 42.5 months after vasectomy and the men (mean age 43.8 ± 5.2 years) experienced pain for 50.3 ± 34.9 months before vasovasostomy. After vasovasostomy improvement of pain occurred in 93% (13 of 14) and 50% were rendered pain-free with an average improvement in pain intensity scores of 65% (p <0.005). Of the men 15% (2 of 13) had a recurrence of pain to baseline but overall 79% (11 of 14) had a durable positive response. Quality of life was significantly improved after vasovasostomy (p <0.005) and 93% (13 of 14) of the patients said they would undergo the same operation again. CONCLUSIONS: Vasovasostomy is an effective treatment modality for the post-vasectomy pain syndrome, and it can achieve robust and durable long-term improvement in pain intensity and quality of life.

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
