OBJECTIVE: In this study, we aimed toinvestigate the relation of testicular torsion and weatherconditions, and to report results from Turkey, a countrylocated between temperate and sub-tropical climatezones.METHODS: A total of 56 patients that had surgery withthe diagnosis of testicular torsion in Ankara Educationand Research Hospital Urology Clinic between 2005and 2014 were included in the study. Age of thepatient, side of torsion, date and time at onset of pain,scrotal exploration time, ischemia duration, degreeArch. Esp. Urol. 2015; 68 (10): 750-754of cord torsion, the surgical procedure performed,and scrotal Doppler ultrasound (USG) findings at thetime of diagnosis and 1 month after surgery wereretrospectively analyzed. The web archives of TurkishRepublic Meteorology General Directorate was used todetermine the seasonal and mean temperatures at thetime of diagnosis. The data were analyzed with SPSSv. 16 statistical package program using Chi-square,Mann-Whitney U and Wilcoxon tests.RESULTS: The mean age of 56 males included in thestudy was 18.88 ± 0.73 years. Right testicular torsionwas seen in 23, and left testicular torsion was seen in 33patients. Testicular arterial flow was absent in 37, arterialflow was moderately decreased in 12, and significantlydecreased in 7 patients on Doppler USG. Detorsionprocedure was performed in 46 patients while 10patients had orchiectomy. Nine patients were admittedin summer, 14 in fall, 15 in winter, and 18 in spring.The mean air temperature at the time of admittance was9.31 ± 1.05ºC. The prevalence of testicular torsionwas not found different among the seasons (p=0.39).The analysis of air temperature at the time of admittanceof the patients revealed that it was below 15ºC in 40patients while it was above 15ºC in 16 patients, with asignificant difference in between (p=0.002).CONCLUSIONS: The prevalence of testicular torsion didnot change in relation with the seasons. However, it wasdetermined that its prevalence was directly proportionalto the air temperature, and increased particularly below15ºC
