Relationship between varicocele and platelet indices: changes of mean platelet volume before and after operation

The correlation between the increased mean platelet volume and varicocele is controversial.

We designed this research to demonstrate the correlation relationship between varicocele and mean platelet volume by studying the changes of mean platelet volume in patients with varicocele before and after operation.

A total of 317 patients with left unilateral varicocele underwent operation, and 293 healthy adult males were enrolled in the study. We collected diagnostic data for preoperative patients through physical examination, color Doppler ultrasonography, and blood routine, and recorded the follow-up data at 6 months after operation for varicocele. Platelet indices and the degree of varicocele or the diameter of spermatic vein correlation analysis were performed. Mean platelet volume values of preoperative and 6-month postoperative were statistically evaluated.

We found that the degree of varicocele and the diameter of spermatic vein were positively correlated with mean platelet volume (p = 0.001 or p < 0.001). When the left unilateral varicocele patients and healthy subjects were compared, there was a significant increase in mean platelet volume (p = 0.003). Mean platelet volume values of 96 varicocele patients who were cured by operation for varicocele after 6 months were decreased significantly more than preoperative (p = 0.039), but 32 varicocele patients of 6-month postoperative recurrence could not prove this change (p = 0.930).

Our research proves that mean platelet volume was positively correlated with the degree of varicocele and the diameter of spermatic vein and varicocele patients showed significantly higher mean platelet volume than healthy subjects. The mean platelet volume of varicocele patients cured by operation for varicocele after 6 months was lower than before, but there was no difference in mean platelet volume between 6-month postoperative recurrent patients with preoperative.
