The incidence of asymptomatic patent processus vaginalis (PPV) does not significantly decrease with age. However, age and gender play an important role in the development of MCIH from PPV.
Purpose: In the present study, we report the incidence of CPPV with unilateral inguinal hernia and future MCIH, with the aim of assisting treatment of this disease.
Methods: A total of 20 636 cases of unilateral inguinal hernia that were surgically treated between January 2002 and December 2009 were retrospectively evaluated. Statistics were performed using Pearson test or χ2 as appropriate, and p < 0.05 was considered statistically signiﬁcant.
