Abstract
Purpose
Many attempts are being made to find an association between varicocele characteristics and sperm parameters. In this study, we investigated the association between a newly introduced varicocele reflux grading pattern and sperm parameters, as well as its effect on spermogram improvement after varicocelectomy.
Methods
In a prospective study, 73 patients with a clinical single-sided varicocele who underwent corrective varicocelectomy were included. Reflux pattern was determined on Color Doppler Ultrasound (CDUS) and categorized into four grades: grade 1 (retrograde), grade 2 (augmentation), grade 3 (enhancement), and grade 4 (stasis). The association of pre- and postoperative spermogram with the patients’ reflux pattern was evaluated.
Results
A significant positive association was found between the venous diameter and reflux pattern. Higher grades of the reflux pattern were associated with the more severe hemodynamic pattern of the reflux (shunt type). A significant association was found between the reflux pattern and preoperative semen characteristics, and this association was more prominent in constant venous diameter. In this respect, the enhancing reflux type was associated with the most impaired preoperative sperm count, motility, and morphology. The enhancing type also revealed the most improvement in spermogram after varicocelectomy.
Conclusion
Patients with a higher reflex grade, particularly enhancing pattern, will most benefit from the surgical correction of varicocele. These findings suggest reflux pattern as a promising prognostic factor for a favorable outcome after varicocelectomy.
