Objective:

To identify preoperative predictors of contralateral patent processus vaginalis (CPPV) and evaluate sex-specific risk factors in children with unilateral inguinal hernia or hydrocele.

Approach:

Key Findings:

• The detection rate of CPPV in children undergoing laparoscopic repair for unilateral inguinal hernia is 38.5%.
• Younger age and female sex were identified as independent risk factors for CPPV.
• Age < 1 year and left-sided hernias were significantly associated with CPPV.

Interpretation:

Preoperative prediction of CPPV risk may inform surgical decision-making and contralateral inspection during laparoscopic procedures.

Limitations:

• The study is retrospective and may have inherent biases.
• Ultrasonography was not routinely performed, potentially affecting the detection of CPPV.

Conclusion:

Identifying preoperative factors associated with CPPV can enhance surgical planning and patient management in pediatric inguinal hernia cases.
