Existing evidence is of low quality with no randomized controlled studies comparing approaches. We provide the first population-based analysis of embolization vs surgical management of varicocele. METHODS: All patients in the province of Ontario who underwent treatment of their varicocele between April 1, 2002-March 31, 2012 were identified using ICES databases. The index intervention was considered the approach first used in the treatment-naïve patient – open surgery or embolization. The primary outcome was the rate of reintervention while secondary outcomes included complications and healthcare utilization. RESULTS: We identified 557,650 male patients with a varicocele diagnosis, of whom n=3,180 underwent an intervention and were included in the study – n=2,139(67%) underwent open varicocelectomy while n=1,041(33%) underwent embolization as their index intervention (Figure 1). Reintervention was more common amongst those who underwent embolization compared to those who underwent surgical management [n=97(9.3%) vs n=142(6.6%);p<0.01]. While controlling for demographics, regression analysis showed surgical varicocelectomy was still less likely to require reintervention [OR 0.68(0.52-0.90);p<0.01].Those who underwent surgical management had higher rates of complications requiring ED visits within 1 month of the procedure. This association was persistent on regression analysis, controlling for demographics [OR 1.69(1.27-2.25);p<0.01]. There was no difference in hospital admissions between the groups [OR 1.53(0.94-2.49);p=0.087].There was a weak association between socioeconomic status (SES) and type of index intervention with the least wealthy income quintile more likely to receive surgery [OR 1.27(1.01-1.60);p=0.04] while there was no difference based on rurality and age. CONCLUSIONS: This first population-based study to examine surgical management vs embolization for treatment of varicocele shows that surgery is less likely to require repeat intervention but with a modest increased risk of complications.

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.
