ABSTRACT 32 boys with symptoms of an acute scrotum had testicular sonography with color flow imaging (CFI). Patients ranged in age from 4-15 years (avg = 11 yrs). Symptoms were present from 12 h to 5 days (avg = 42 hrs). CFI correctly predicted presence or absence of testicular perfusion in 11 boys who had surgical exploration of the scrotum. 8 of these 11 patients had hemorrhagic infarction of the testicle, 1 had torsion of the appendix epididymis, 1 had epididymitis, and 1 had bilateral incomplete torsions with normal testicular perfusion. The remaining 21 patients did not have an operation. At least a 1 year follow-up of all patients has shown no clinical evidence of testicular atrophy to suggest a missed diagnosis of torsion. Absence or markedly decreased testicular flow was easily identified and indicates testicular ischemia/infarction. Conversely, hyperemia of the testis and/or epididymis is usually associated with trauma or infection. However, incomplete torsion or spontaneous detorsion may demonstrate normal testicular flow on CFI. Only close correlation of clinical symptomatology and gray scale findings with CFI can identify these patients, who remain at high risk for subsequent complete torsion and infarction.

    ABSTRACT: Several aspects of the management of suspected testicular torsion are controversial. A questionnaire was mailed to all 33 consultant urologists in the North West region of England to elicit their policies for routine clinical management. 29 of 33 questionnaires were returned (2 incomplete). As regards radiological investigation, 4 consultants always request ultrasound examination; the others do not favour routine imaging. When the diagnosis of testicular torsion is confirmed at operation, all consultants would perform bilateral testicular fixation, although with considerable variations in technique; most use Vicryl sutures (66%) and three-point fixation (57%). One-third would do an ipsilateral orchidopexy if there was no clear evidence of testicular torsion at operation. The variation revealed by this survey prompted an attempt to formulate a protocol for management. A review of the published work indicates that, in cases of proven testicular torsion, treatment should include bilateral fixation with delayed-absorption or non-absorbable sutures; fixation should be at three points. When torsion is not found at operation, there is no evidence of benefit from orchidopexy.

    ABSTRACT: To compare testicular color Doppler sonography with testicular scintigraphy in differentiating between surgical and nonsurgical conditions of the pediatric testis, and to evaluate the role of testicular color Doppler sonography in the pediatric population. Forty-six children (age range, 1 day to 18 years; median age, 11 years) with acute scrotal pain were evaluated with both scintigraphy and color Doppler sonography by two separate groups of radiologists who had no knowledge of the results of the other modality. The final radiologic diagnosis was classified as a surgical condition, nonsurgical condition, or indeterminate and was compared with the patient's surgical diagnosis or clinical diagnosis, which was established by response to treatment and follow-up. Sonography correctly diagnosed 11 of 14 surgical conditions and 31 of 32 nonsurgical conditions. There was one indeterminate sonogram. There were no false-positive examinations, and there were three false-negative examinations (sensitivity = 78.6% [95% CI, 66.7-90.5%], specificity = 96.9% [95% CI, 94.3-99.5%], accuracy = 91.3%). Color flow was demonstrated in the asymptomatic testis in 34 of 44 boys. Scintigraphy correctly diagnosed 11 of 14 surgical conditions and 29 of 32 nonsurgical conditions. There were two indeterminate scintigrams. There were two false-positive examinations and two false-negative examinations (sensitivity = 78.6% [95% CI, 66.7%-90.5%], specificity = 90.6% [95%CI, 82.2%-99.0%], accuracy = 87.0%). Color Doppler sonography and scintigraphy show similar sensitivity for the diagnosis of testicular torsion. A small number of false-negative cases can occur with either modality. The two studies may provide complementary information in indeterminate cases.
