Final answer:
Orchiopexy is a surgical procedure used to correct cryptorchidism, a condition involving undescended testicles in infants or young boys, which is important for fertility and reducing the risk of testicular cancer.
Step-by-step explanation:
The surgical procedure known as orchiopexy is typically used to correct cryptorchidism, which is the medical term for undescended testicles. This condition is where one or both of a baby boy's testicles have not moved into their proper place in the scrotum. Orchiopexy is performed to bring the testicles down into the scrotum and is usually done in infancy or early childhood.
Cryptorchidism is important to correct not only for fertility reasons but also because it can increase the risk for developing testicular cancer later in life. A biopsy during orchiopexy may be performed if there is any suspicion of abnormal cells or tissue. As cryptorchidism is a disorder of the male reproductive system, the other disorders listed (nocturnal enuresis and urinary reflux disorder) are not treated with orchiopexy.
