Predictive role of hematological parameters in testicular torsion and epididymo-orchitis in adolescents

OBJECTIVE: This study aimed to evaluate the effects of epididymo-orchitis and testicular torsion on hematological parameters in adolescents. MATERIAL and METHODS: The data of the patients who applied to the tertiary health care institution between 2018 and 2023 with complaints of acute scrotal pain were evaluated retrospectively. Adolescent patients diagnosed with epididymo-orchitis and testicular torsion were included in the study. Complete blood count parameters (Neutrophil, lymphocyte, monocyte, platelet counts, and mean platelet volume) and inflammation markers (LMR, NLR, PLR, SII index, SIRI index) were compared between testicular torsion and epi-didymo-orchitis groups. In addition, the data of patients with testicular torsion were compared be-tween those with testicular fixation and those with orchiectomy. RESULTS: Forty patients were in the testicular torsion group, and 54 were in the epididymo-orchitis group. Mean lymphocyte counts and platelet counts were statistically significantly higher in the epididymo-orchitis group (p=0.001 and p=0.008, respectively). The median neutrophil count was higher in the torsion group (p=0.001). The median LMR value was statistically higher in the epididymo-orchitis group, while median NLR and median PLR values were higher in the torsion group (p=0.003, p=0.001, and p=0.019, respectively). The median SII and SIRI values were statistically significantly higher in the torsion group. The median monocyte count was significantly higher in the orchiectomy group com-pared to the fixation group (p=0.001). The median LMR value was 4.1 in the fixation group and 2.2 in the orchiectomy group (p=0.025). The median SIRI value was 1.9 in the fixation group and 4.6 in the orchiectomy group (p=0.012). CONCLUSION: Since testicular torsion is an ischemic process other than inflammation, it affects hematologic parame-ters more than epididymo-orchitis in the early period. In torsion patients, monocyte count, LMR value and SIRI index may predict the possibility of orchiectomy. Keywords: adolescent, complete blood count, epididymo-orchitis, testicular torsion
