Tests and diagnosisBy Mayo Clinic staff
Your doctor will ask you a number of questions to verify whether your signs and symptoms are caused by testicular torsion or something else. Doctors often diagnose testicular torsion with just a physical exam of your scrotum, testicles, abdomen and groin. Your doctor may also test your reflexes by lightly rubbing or pinching the inside of your thigh on the affected side. Normally, this causes the testicle to contract. This reflex may not occur if you have testicular torsion.
Sometimes medical tests are necessary to confirm a diagnosis or to help identify another cause for your symptoms. These include:
- Urine test to check for infection.
- Scrotal ultrasound to check blood flow. Decreased blood flow to the testicle is a sign of testicular torsion. But ultrasound doesn't always detect the reduced blood flow, so the test may not rule out testicular torsion.
- Surgery is sometimes necessary to determine whether your symptoms are caused by testicular torsion or another condition.
If you've had pain for several hours and your physical exam suggests testicular torsion, you may be taken directly to surgery without any additional testing. Delaying surgery might result in loss of the testicle.
