Ultrasonography (US) is a medical technology that uses sound waves to create images of internal structures of the body. Additionally, some US devices utilize additional technologies not only to assess the physical structure and position of internal parts of the body, but also to evaluate their function. As a result, US is a widely accepted technique in the evaluation of scrotal conditions, allowing for medical evaluation of serious conditions without the need for invasive surgery or techniques that expose individuals to radiation.
The American Institute of Ultrasound Medicine (AUIM) published its Practice Guideline for the Performance of Scrotal Ultrasound Examinations in 2011. This document, which was jointly developed with the American College of Radiology (ACR) and Society of Radiologists in Ultrasound, provides guidance for a wide variety of indications where US is understood to be beneficial. Such indications include acute scrotum, which may be caused by a wide variety of conditions. US evaluation for acute scrotum is supported by over 20 years of study data indicating sensitivity between 70-100% and specificity between 88-100% (Al Mufti, 1995; Paltiel, 1998, Vajayaraghavan, 2006; Wilbert, 1993; and Yazbeck, 1994). One of the most common causes of acute scrotum is testicular torsion. Several studies have investigated the use of US for the evaluation of this condition specifically, indicating sensitivity between 63-86%, specificity between 89-100%, and accuracy between 99-100% (Baker, 2000; Baldisserotto, 2005; Burks, 1990; Kalfa, 2007, and Karmazyn, 2005). The most recent data, from a large study conducted by Yagil and colleagues, reported that sensitivity, specificity, and accuracy of US was 94%, 96%, and 99.5% for testicular torsion, 92%, 95%, and 94% for testicular malignancy, and 100%, 98.5%, 98.5% for testicular hematoma, respectively. This study also reported on the beneficial use of US for hydrocele, hernia, testicular mass, abscess, chryptorchidism, and orchiepididymitis. Additional indications have also been studied elsewhere, including infertility. Pierik and others conducted a large study of 1372 subjects with suspected infertility, in which they reported sensitivity of 65.7% and specificity of 91% (1999).
The ACR, in its Appropriateness Criteria for children and adults with acute onset of scrotal pain without trauma or antecedent mass, rates US of the scrotum a 9 out of 9, indicating "usually appropriate" (2011). They comment that color doppler ultrasound "is the study of choice to evaluate patients with acute scrotal pain due to its widespread availability and its ability to diagnose testicular torsion with a high degree of sensitivity and specificity and to distinguish other causes of scrotal pain and swelling."
The American Urological Association, as part of its "Choosing Wisely" initiative, has published a document titled "Five things physicians and patients should question" (2013) that lists 5 common medical procedures or treatments that they recommend against. The fifth item on the list is "Don't perform ultrasound on boys with cryptorchidism." They provide the following rationale for US for this statement regarding undescended testis:
Ultrasound has been found to have poor diagnostic performance in the localization of testes that cannot be felt through physical examination. Studies have shown that the probability of locating testes was small when using ultrasound, and there was still a significant chance that testes were present even after a negative ultrasound result. Additionally, ultrasound results are complicated by the presence of surrounding tissue and bowel gas present in the abdomen.
This statement is supported by a meta-analysis published by Tasian and Copp (Tasian, 2011b). The result of this study found that US for undescended testis has a sensitivity of 45% (95% confidence interval [CI]: 29–61) and a specificity of 78% (95% CI: 43–94). The positive and negative likelihood ratios are 1.48 (95% CI: 0.54–4.03) and 0.79 (95% CI: 0.46 –1.35), respectively. The authors stated that a positive ultrasound result increases and negative ultrasound result decreases the probability that a nonpalpable testis is located within the abdomen from 55% to 64% and 49%, respectively. They conclude; "Ultrasound does not reliably localize nonpalpable testes and does not rule out an intraabdominal testis. Eliminating the use of ultrasound will not change management of nonpalpable cryptorchidism."
Hydroceles: A condition where there is abnormal fluid buildup within the scrotum around the testicle.
Metastatic germ cell tumors: Cancer cells that are derive from cells involved with the production of sperm or eggs, which have migrated from their point of origin to another location in the body.
Occult primary tumor: A cancer cell that has an unknown point of origin.
Testicular ischemia: A condition where blood supply to the testes is insufficient.
Testicular neoplasm: Cancer of the testes.
Testicular torsion: A condition where the spermatic cord suspending the testicles becomes twisted, interfering with normal blood supply.
Undescended testes: Also known as cryptorchidism. A condition characterized by absence of one or both testes from the scrotum.
Varicoceles: A condition where the complex of veins draining from the structures within the scrotum becomes enlarged.
