Scrotal Ultrasound for Pain: Low Frequency of Absolute Surgical Indications

Objective To examine the results of scrotal ultrasounds (US) conducted for scrotal or testicular pain and review the pathologic findings of orchiectomies done for lesions that were suspicious for malignancy on US. Materials and Methods We retrospectively reviewed the indications and findings of all scrotal US completed at our institution from 2002 to 2014. If a patient underwent an orchiectomy for an intratesticular lesion that was concerning for malignancy on US, the pathology report was also reviewed. Results There were 18,593 scrotal US performed, with 7,668 (41.2%) conducted for scrotal pain. Of the US performed for pain, 80.4% revealed benign or normal findings, and only 2.2% demonstrated a finding that is an absolute indication for surgery (intratesticular lesion suspicious for malignancy 0.8%, abscess 0.7%, torsion 0.6%, infiltrative process such as lymphoma 0.1%). For those patients undergoing an orchiectomy, 75% had malignancy on pathologic analysis. Conclusion The majority of the 7668 US performed to evaluate scrotal or testicular pain reveal normal or benign findings. A low percentage demonstrates a finding that necessitates urgent or emergent surgery.
