Purpose: The aim of this study was to compare incidence of mumps parotitis in our region and mumps orchitis in our hospital, and assess risk factors related to testicular atrophy.
Materials and Methods: This retrospective study examined the records of 26 post-pubertal patients (mean age 17.2±2.3years) with mumps orchitis from March 2008 to January 2010. These patients were divided into two groups according to the presence of the testicular atrophy (atrophy: group 1, no atrophy: group 2). The national and regional incidence of mumps parotitis was investigated from homepage of Korean Center for Disease Control and Prevention. We also evaluated several risk factors such as time intervals in onset of mumps, mumps orchitis, and admission, and disease severity including WBC, CRP, testicular volume ratio and duration of treatment.
Results: The total number of mumps orchitis in our hospital were 0, 8, 28 cases from 2007 to 2009, respectively. The incidence of mumps parotitis in Gyeonggi province from 2008 to 2009 (1,276 and 1,886 cases, respectively) was greater than 2007 (699 cases). The testicular atrophy was developed in 10 patients (38.5%) (group 1), not in 16 patients (61.5%) (group 2). The duration between onset of the first symptoms of mumps and admission in group 1 (4.8 days) was shorter than that of group 2 (7.3 days).
Conclusions: The increasing incidence of mumps orchitis in our hospital from 2008 seems to be correlated with surge of mumps parotitis in our province. The early spread of mumps virus to testis and rapid progression may be the main risk factor related to testicular atrophy rather than late in the treatment or severity of testicular swelling.
