What is the critical timeframe for performing orchidopexy after symptoms start in a case of testicular torsion?

In cases of testicular torsion, the critical timeframe for performing an orchidopexy is within 6 hours of symptom onset. This time frame is crucial because the testicle's blood supply can become compromised rapidly after twisting; if blood flow is not restored, it can lead to irreversible ischemic damage. The likelihood of salvaging the affected testis diminishes significantly after this 6-hour window. Successful intervention within this period greatly increases the chances of preserving testicular function and preventing complications such as necrosis or infertility.

Longer delays, such as 12 hours, 24 hours, or beyond, substantially increase the risk of losing the testicle due to prolonged ischemia, which is why immediate surgical intervention is critical upon diagnosis and initiation of symptoms.
