Tension hydrocele as an additional cause of acute scrotum: case series and literature review.

Purpose: To describe the correlation between acute scrotum pain and tension hydrocele, focusing on US and Doppler features.

Methods And Materials: We evaluated retrospectively a series of five patients with a long history of hydrocele who were referred to our institutions for increasing acute scrotal pain. Patients were approached with gray scale US of both testes, as well as with color-Doppler and spectral analysis, comparing the results with those after aspiration and symptoms relief.
