Evaluation of Acute Scrotal Pain by Color-Coded Duplex Sonography

In light of the high sensitivity of color-coded duplex sonography (CCDS), we analyzed a group of patients with acute scrotal pain to evaluate the use of CCDS in routine clinical examination. During March 1988 through April 1991, CCDS was used in 31 patients with acute scrotal pain before they underwent surgery in our department. In 15 patients, the structural and perfusion changes of the scrotal contents were such that a definitive diagnosis was possible. In the rest of the patients, the pathologic changes seen with CCDS were more complex, and the correct interpretation needed more expertise; this was especially true in patients with partial torsion, posttorsion status, and torsion of hydatids. CCDS with the simultaneous display of anatomic scrotal structures and blood flow over the entire scan field is an excellent method for evaluating patients with acute scrotal pain. However, apart from the classical case of no perfusion (as in testicular torsion) and increased perfusion (as in inflammation), more complex changes are more difficult to interpret. The correct diagnosis in the latter cases requires considerable experience and evaluation of all facts, including clinical history, results of palpation, and structural and perfusion changes of the scrotal contents.
