The value of serum mean platelet volume in testicular torsion

Abstract

Objective To compare the serum mean platelet volume (MPV) in patients with testicular torsion and healthy control subjects.

Methods This retrospective study compared clinical and demographic data from patients who underwent surgery for testicular torsion and healthy controls. Testicular torsion was diagnosed with a physical examination and Doppler ultrasonography. Age, leukocyte count, platelet count and MPV were recorded for all participants.

Results A total of 50 patients with testicular torsion and 51 healthy control subjects were enrolled. There was no significant difference in age and platelet count between the two groups. Patients with testicular torsion had a significantly higher leukocyte count and MPV, compared with controls. According to receiver operating characteristic curve analysis performed for the prediction of testicular torsion, the best cut-off point for MPV was 7.7fl (sensitivity 62%, specificity 96%), and the best cut-off point for leukocyte count was 9.5x10(9)/l (sensitivity 58%, specificity 80%).

Conclusions The MPV may be useful as an ancillary test for the diagnosis of testicular torsion. Further studies are needed in order to confirm these preliminary results.
