What does orchidopexy secure?

Orchidopexy is a surgical procedure primarily performed to correct cryptorchidism, a condition where one or both of the testes fail to descend into the scrotum. The procedure involves securing the testicle in a proper position within the scrotum or adjacent to the thigh.

By attaching or anchoring the testis to the thigh fascia, orchidopexy helps prevent retraction or movement of the testes back into the abdominal cavity. This positioning is important not only for the anatomical correctness but also for normal spermatogenesis and reducing the risk of testicular torsion or future complications.

Comparatively, the other options refer to different anatomical relationships: linking the bladder to the pelvic wall pertains to a separate surgical procedure for bladder fixation; the prostate gland's relation to the urethra involves procedures addressing urinary issues rather than testicular positioning; and securing the kidneys to the abdominal wall is associated with surgical techniques for treating conditions like nephroptosis or kidney mobility. Therefore, the choice relating to the testis directly aligns with the definition and intent of orchidopexy.
