In simple words: A congenital hydrocele is a condition present at birth where fluid collects in the sac around a baby boy's testicle. It happens when part of the belly lining doesn't close properly as the testicle moves down into the scrotum during development in the womb.

A congenital hydrocele is a fluid-filled sac surrounding a testicle that is present at birth. It develops during fetal development when a portion of the abdominal lining fails to close properly around the testicle as it descends into the scrotum. This allows fluid from the abdomen to flow into the scrotum and collect around the testicle.

Example 1: A newborn male infant is examined shortly after birth, and the physician notes a painless swelling in the scrotum. Transillumination of the scrotum confirms the presence of fluid, consistent with a congenital hydrocele. Observation is recommended., A 6-month-old male infant presents with a persistent, non-tender scrotal swelling.The pediatrician diagnoses a congenital hydrocele that has not resolved spontaneously.Surgical repair is considered., A baby boy is born with a large scrotal swelling. After careful examination and imaging, the physician diagnoses a congenital hydrocele and rules out other conditions such as inguinal hernia. The parents are reassured and advised on observation and follow-up.

Documentation should include a detailed physical exam of the genitalia, noting the size, location, and characteristics of the swelling. Transillumination findings are crucial. Any associated symptoms or abnormalities should also be documented. Imaging studies, if performed, should be included.The physician’s assessment, diagnosis, and plan of care should be clearly documented.
