The Canal of Nuck is an anatomical structure in the female human body, named after the Dutch anatomist, Anton Nuck. It is a tubular extension of the parietal peritoneum that follows the round ligament of the uterus into the labia majora.

Anatomy

The Canal of Nuck is a vestigial remnant of the processus vaginalis in females. In males, the processus vaginalis is obliterated after the descent of the testes, but in females, it may persist as the Canal of Nuck. The canal extends anterior to the round ligament of the uterus, through the inguinal canal, and terminates in the labia majora.

Clinical Significance

The Canal of Nuck can be a site for the development of hydroceles and hernias. A Nuck hydrocele is a collection of fluid within the canal, while a Nuck hernia involves the protrusion of abdominal contents through the canal. Both conditions can present with a painless swelling in the groin or labia majora and are typically diagnosed via ultrasound.

Diagnosis and Treatment

Diagnosis of conditions related to the Canal of Nuck is typically made via physical examination and confirmed with imaging studies, such as ultrasound or MRI. Treatment often involves surgical intervention to remove the hydrocele or repair the hernia.

History

The Canal of Nuck was first described by Anton Nuck in the 17th century. Nuck was a Dutch anatomist and surgeon who made significant contributions to the understanding of human anatomy.
