Purpose: The value of contralateral groin exploration for a child with unilateral inguinal hernias or communicating hydrocele has been hotly debated. The aim of this study is to investigate the possibility of developing contralateral hydrocele or inguinal hernia in children who underwent repair for a unilateral hydrocele or hernia, and we quantified the risks for this.
Patients and Methods: We conducted a retrospective study of two hundred patients who presented for unilateral hydrocele repair between October 1994 and December 2000. The patients with contralateral occurrence were defined as those who had undergone previous unilateral hydrocele repairs and they had no clinical evidence of contralateral hydrocele at the time of the initial operation.
Results: The mean age at operation was 3.5 years (range: 0.5-13 years) and the follow-up ranged from 0.5 to 7.6 years (mean: 3.5 years). The proportion of right hydrocele or inguinal hernia was 62.5% and that of left was 37.5%. Contralateral hydrocele or inguinal hernia developed in 19 patients (9.5%). The age at the initial operation, the side of the hydrocele, a history of preterm birth, a familial history and a history of low birth weight, a history of hypospadias and a history of undescended testis did not influence the incidence of developing contralateral hydrocele.
Conclusions: The risk of a contralateral hydrocele or inguinal hernia after unilateral repair was 9.5%. The low possibility of developing contralateral hydrocele or inguinal hernia in a child who previously underwent repair does not justify routine contralateral groin exploration. We should pay attention to determine the risk factors for developing a contralateral hydrocele or inguinal hernia.
