2. spermatic cord block(English)

   • should be performed to determine if the pain is being generated from within the scrotum. We recommend that this block be performed by injecting 20 mL of 0.25% bupivacaine/ropivacaine without epinephrine into the spermatic cord at the level of the pubic tubercle. If the pain signal is conducted via the spermatic cord nerves, the pain should be temporarily relived after performing the cord block
