RESUMEN
OBJECTIVE: This study sought to evaluate platelet volume indices (mean platelet volume [MPV], platelet distribution width [PDW], and platelet large cell ratio [P-LCR]) in varicocele patients, and compare it with platelet volume parameters in healthy controls. METHODS: This cross-sectional study involved 2 groups: group 1 included 51 varicocele subjects and group 2 consisted of 50 healthy control subjects of similar ages. Peripheral venous blood samples were collected with ethylenediaminetetraacetic acid-K2 anticoagulant between 8:30 AM and 10 AM following an overnight fast. Platelet volume parameters (MPV, PDW, and P-LCR) were measured in both groups within 2 hours of sampling. RESULTS: The mean PDW, MPV, and P-LCR were 13.9+/-2.5%, 10.1+/-1.3 fL, and 27.3+/-7.8% in varicocele patients, respectively, and were 12.6+/-2.4%, 9.3+/-1.1 fL, and 21.9+/-6.4% in the control group, respectively. The mean PDW, MPV, and P-LCR were significantly higher in the varicocele group than the control group. CONCLUSION: The results of the present study suggest that vascular components may play an important role in the pathophysiology of varicocele; therefore, there is a great need for prospective studies to confirm this relationship.
