A testicular ultrasound (scrotal ultrasound) is a non-invasive medical imaging test that uses high-frequency sound waves to create detailed pictures of the testicles and surrounding scrotal tissues. This procedure is commonly used to diagnose pain, swelling, or lumps, helping distinguish between fluid-filled cysts and solid masses. The actual time spent actively scanning is relatively short, typically lasting fewer than 30 minutes.
Preparing for the Ultrasound
Unlike some other imaging tests, a testicular ultrasound requires minimal preparation. Patients do not need to restrict food or drink intake, or arrive with a full bladder.
Patients should wear comfortable, loose-fitting clothing. They will need to remove all clothing and jewelry from the waist down before the procedure. The clinic may provide a gown to wear during the examination.
The Duration of the Scan Itself
The active scanning time is brief, with most testicular ultrasounds completed within 15 to 30 minutes. This duration covers the time from when the sonographer begins applying the gel to when they finish capturing the necessary images.
The specific time can vary based on the clinical reason for the examination, particularly whether it is a unilateral or bilateral scan. While both testicles are often examined for comparison, a search for a complex finding or a suspected condition like testicular torsion may lengthen the process. Performing a color Doppler ultrasound, which assesses blood flow to the area, also adds a few minutes. If initial images are unclear or an unexpected abnormality is found, the technologist will spend additional time acquiring clearer views, potentially extending the procedure toward the 30-minute limit.
What Happens During the Procedure
The procedure begins with the patient lying face-up on an examination table, often with the legs spread slightly for better access. The sonographer adjusts the position and may use a towel or tape strips to gently elevate and stabilize the scrotum.
A water-based gel is applied directly to the scrotal skin. This gel eliminates air pockets and facilitates the smooth transmission of sound waves from the transducer into the body. The sonographer then uses a small, handheld probe (transducer) and moves it across the scrotal surface.
As the transducer moves, it sends and receives sound waves, creating real-time images on a connected monitor. The technologist may apply light pressure to obtain clear images from different angles. While the procedure is generally painless, patients with existing tenderness or swelling might feel minor discomfort from the pressure. Once all necessary images are acquired, the sonographer wipes the gel away, concluding the active imaging process.
Total Appointment Time and Immediate Follow-up
While the scan itself is brief, the total time a patient spends at the clinic is significantly longer. This overall appointment duration accounts for essential administrative and logistical steps surrounding the imaging procedure.
Patients typically arrive 15 to 30 minutes early to complete check-in, registration, and paperwork. Time spent undressing, waiting for the sonographer, positioning on the table, and redressing afterward can easily add another 10 to 15 minutes. After the scan, the technologist reviews the captured images to ensure quality before the patient is released. Patients should generally plan for at least an hour for the entire clinic visit.
