Athletics rookie Joshua Kuroda-Grauer suffered a ruptured testicle after fouling off a pitch during Monday night's 5-2 victory over the Arizona Diamondbacks, an injury that required emergency surgery and temporarily halted the 23-year-old infielder's promising Major League Baseball season.
Kuroda-Grauer initially left the game with what the Athletics described as a testicular contusion, or bruising caused by blunt trauma. He was later taken to St. Joseph's Hospital in Phoenix, where an ultrasound revealed the more serious injury, according to the team.
According to the Athletics' manager, Mark Kotsay, the rookie is now recovering comfortably in the hospital after undergoing surgery and said the infielder remained in "good spirits."
"He was joking about it... He's such a great kid. Unfortunate to have lost him, given the way he was performing and the way he was integrated into this group. He fit right in," Kotsay said.
The Athletics placed Kuroda-Grauer on the 10-day injured list ahead of Tuesday's game against the Diamondbacks.
A direct blow to the groin can cause far more than temporary pain. In some cases, the force can damage the protective covering surrounding the testicle and require urgent surgery to prevent permanent complications.
How Can a Foul Ball Rupture a Testicle?
A baseball can travel at speeds exceeding 90 mph, creating enough force to cause significant trauma when it strikes the body.
The testicles are particularly vulnerable because they are located outside the body and are protected primarily by the scrotum rather than bone or muscle. Although the testicles are surrounded by a tough layer of tissue called the tunica albuginea, a powerful impact can tear that covering.
Testicular rupture occurs when blunt trauma breaks the tunica albuginea and allows the tissue inside the testicle to protrude or become damaged.
A direct hit from a baseball, cricket ball, or other high-speed object is among the potential causes of this type of injury.
Why Is Testicular Rupture an Emergency?
Testicular rupture is considered a urologic emergency because delaying treatment can increase the risk of losing the injured testicle.
Severe trauma can damage the blood supply and cause bleeding or swelling inside the scrotum. If the injury is not treated promptly, the damaged tissue may become nonviable, potentially requiring removal of the testicle.
Early treatment, however, may allow doctors to repair the damaged tissue and preserve testicular function. Prompt evaluation is important when significant testicular trauma occurs.
Pain after a blow to the groin is common, but certain symptoms may indicate a more serious injury.
Warning signs can include:
- Severe or persistent testicular pain
- Significant swelling of the scrotum
- Bruising or discoloration
- Tenderness that does not improve
- Blood in the urine
- Difficulty urinating
- An abnormal position or shape of the testicle
- Fever
Some athletes may initially believe an injury is simply a bruise and attempt to continue playing. However, persistent or severe pain after a direct impact should not be ignored.
How Do Doctors Diagnose a Ruptured Testicle?
Doctors typically begin with a physical examination and may use an ultrasound to determine the extent of the damage.
A scrotal ultrasound with Doppler imaging can help physicians assess blood flow and identify signs of rupture, bleeding, or other structural injuries.
In Kuroda-Grauer's case, the ultrasound performed after he was taken to the hospital revealed the rupture and led to emergency surgery.
Surgery is generally recommended when imaging confirms testicular rupture or when doctors cannot rule out significant damage.
During surgery, physicians can repair the torn tissue, control bleeding, and remove damaged tissue when possible. In severe cases where the testicle cannot be salvaged, removal may be necessary.
The goal is to preserve the testicle and its function whenever medically possible.
Any athlete's instinct may be to shake off a painful hit and return to the game, but groin injuries require special attention.
Even when an athlete can stand or continue moving after an impact, that does not necessarily mean the injury is minor. Significant internal damage can occur without an obvious external wound.
For athletes who sustain a direct blow to the testicles, especially when pain or swelling persists, prompt medical evaluation can make a critical difference.
