Of the catecholamines tried, isoproterenol was the stron...

BACKGROUND Spermatic cord neoplasms are a rare tumor entity and, moreover, of benign behavior. Malignant tumors of the spermatic cord are mostly of mesenchymal origin. We present the unusual case of a giant malignant mesenchymoma of the spermatic cord with bidirectional differentiation into a liposarcoma and a leiomyosarcoma. CASE REPORT A 84-year-old male patient presented with a scrotal mas...

BACKGROUND: Leiomyosarcomas (LMS) of the spermatic cord are extremely rare. Radical inguinal orchiectomy and high ligation of the cord is the standard primary surgical procedure. The extent of surrounding soft tissue excision required and the precise role of adjuvant radiotherapy, however, remains unclear. In addition, recurrence is a commonly encountered problem which might necessitate further...

BACKGROUND Congenital absence of the vas deferens is an important cause of obstructive azoospermia, and the lack of an imaging diagnostic test is a critical problem. The aim of this study is to discuss the use of ultrasonography in congenital absence of vas deferens, including dysplasia of the epididymis and the seminal vesical. MATERIAL AND METHODS Five fresh spermatic cord specimens were dete...

AIM To assess the relation of reactive oxygen species (ROS) and antioxidants in the internal spermatic vein blood compared to the peripheral venous blood. METHODS Sixty-eight infertile oligoasthenozoospemic patients associated with varicocele were investigated. During inguinal varicocelectomy, blood samples of internal spermatic as well as median cubital veins were withdrawn. Three ROS factor...

Arteriovenous malformations of the lower urinary tract are uncommon lesions, usually presenting as scrotal masses. A case of recurrent acute scrotal pain mimicking testicular torsion that was attributed to the presence of an arteriovenous malformation of the spermatic cord is described. To our knowledge this is the first reported case of an arteriovenous malformation of the spermatic cord prese...
