Color Doppler sonography in the diagnosis of acute scrotum in boys.
Evaluation of acute painful scrotum is difficult and imaging studies have been reported to be unreliable in detecting testicular torsion. In order to assess the value of color Doppler sonography in acute scrotal disease, the authors reviewed 65 consecutive boys, ranging in age from 1 to 16 years. The study demonstrated absent or diminished flow signals in 11 patients. All of them had a surgical intervention, and in 8 of them, a testicular torsion was confirmed. 54 boys had a symmetrical or increased flow signal on the affected side. Just 5 boys among this group underwent surgical exploration. On follow up, none of the 54 patients with good flow signals proved to have a testicular torsion. Sonography and color Doppler sonography helped to differentiate epididymitis and torsion of a testicular appendage as a basis for further investigations and correct conservative therapy. In detecting a testicular torsion, color Doppler sonography yielded a positive predictive value of 73%, a sensitivity of 100% and a negative predictive value of 100%. We therefore conclude, that Doppler sonography can reliably rule out testicular torsion so that routine scrotal exploration in cases of acute scrotum is no longer necessary. By reducing the number of emergency operations and hospitalization days, color Doppler sonography can cut down the total cost of managing acute painful scrotum in boys.
