Orchiopexy (or orchidopexy) is a surgery to move an undescended testicle into the scrotum and permanently fix it there. Orchiopexy typically also describes the surgery used to resolve testicular torsion.
Orchidopexy is usually not performed before the age of one years, because most cases resolve spontaneously and operating on very small children needs the highly specialised skills of a pediatric surgeon or a pediatric urologist.
The undescended testicle may be located within the normal line of descent (for example, in the inguinal canal) or high in the scrotum or ectopically (i.e. the abdomen). The surgeon may use an endoscope through the umbilicus to locate the testicle, and through other small opening(s) performs the procedure. The higher the testicle, the less successful the procedure. However, the procedure has a high success rate overall.
Orchiopexy can also be performed to resolve a testicular torsion. If caught early enough and the blood supply can be restored to the testicle, this operation can be performed to prevent further occurrence of torsion. If the blood supply has been interrupted for too long, an orchiectomy must be performed.
