In the period between 1994–96, 16 patients with suspected testicular torsion confirmed during operation, underwent color-Doppler sonography of the spermatic cord after local objective examination. The sonography showed a reduced or absent arterial flow in 15 patients and an increase in flow in 1 patient. In our study, color-Doppler sonography proved to have a sensitivity of 93.7%.

A patient underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis (pT3 G3 N0 M0). After 5 years a CT scan showed a retroperitoneal lymphadenopathy, suspected of being a metastasis. Histological examination of the surgically-removed lymph node showed seminoma. Palpation of the testes was negative. Testicular ultrasonography showed three hypoechoic areas in the right testis. Orchiectomy was subsequently performed and the histological examination of the testis confirmed the presence of seminoma (pT1).
