  • Title: Can haematologic parameters be used to predict testicular viability in testicular torsion?
    Author: He M, Zhang W, Sun N.
    Journal: Andrologia; 2019 Oct; 51(9):e13357. PubMed ID: 31264256.
    Abstract:
    The purpose of this study was to evaluate the predictive value of haematologic parameters for testicular survival in torsion. Children with testicular torsion (TT) treated in Beijing Children's Hospital from January 2006 to December 2018 were enrolled in this study. Patient data collected in this study included age, symptom duration, preoperative preparation time, cryptorchidism testicular torsion or not, spermatic cord torsion degree, orchiectomy/orchiopexy, testicular volume 3 months after operation by ultrasound in orchiopexy patients and haematologic parameters. The orchiopexy group comprised of 54 patients with a mean age of 135.6 ± 43.73 months, and the orchiectomy group included 58 patients with a mean age of 119.36 ± 60.82 months. The multivariate analysis showed that symptom duration (Odds Ratio = 1.11, p < 0.001), spermatic cord torsion degree (Odds Ratio = 1.006, p = 0.002) and mean platelet volume (MPV; Odds Ratio = 3.697, p = 0.044) were significant predictors of orchiectomy. The cut-off value for MPV during window time for orchiectomy was 10.55 fl (10-9  L) and provided a sensitivity of 47.8% and a specificity of 92.6%. This study found that symptom duration, spermatic cord torsion degree and MPV could be indicators of testicular viability in testicular torsion. MPV can provide valuable information before operation which can guide doctors and family members of the patients to select the appropriate treatment.
