ABSTRACT

The purpose of this study was to determine the frequency of scrotal calculi in men referred for scrotal ultrasonography (US), to identify any associated pathologies, and to investigate if any relationship exists between scrotal lithiasis and pain.

This was a retrospective study in which 4084 scrotal US examinations in 3435 men were evaluated. Scrotal US was performed using a high-frequency linear transducer. Forty patients were questioned as to whether scrotal pain was present. Patients were asked to grade their scrotal pain intensity using the Numerical Rating Scale.

Sixty-seven of the 3435 patients with scrotal US examinations had scrotal calculi with a mean size of 3.7±1.4 mm (range, 1.6–7 mm). Twenty patients with scrotal calculi had no scrotal pain. Nine patients with scrotal pain (22.5%) had no US or clinical abnormalities except scrotal calculi.

The frequency of scrotal calculi was 1.95%. Approximately one-quarter of patients with scrotal calculi and pain had no additional abnormalities. Therefore, scrotal calculi should be considered in the differential diagnosis of scrotal pain.
