Ex Input:
Question: Is orchidopexy without ligation of the processus vaginalis associated with an increased risk of inguinal hernia?
Answer: Our findings confirm that division without ligation of a patent processus vaginalis is usually followed by spontaneous peritoneal scarring and complete closure of the internal inguinal ring. Present technique is as effective as traditional orchidopexy and saves extra time spent for meticulous closure of the processus vaginalis or peritoneal tears.

Ex Output:
no
