    ABSTRACT: Urologic resectoscope loops often are manipulated to reposition the angle. The effects of these maneuvers on the efficiency and functionality of the loop have never been tested. Our goal was to evaluate the changes in tensile strength, conductivity, and dispersion of cautery effect resulting from such manipulation. Resectoscope loops manufactured by Karl Storz, Olympus, Boston Scientific, and ACMI were tested for tensile strength and unevenness of cautery effect before and after one manipulation from an angel of 15 degrees posterior to 15 degrees anterior deviation. Prior to manipulation, the loops demonstrated a tensile strength of approximately 40 lb to failure. After one manipulation, the tensile strength was reduced by 90.1% (P < 0.001), with 46.7% of the loops failing to meet minimum industry standards. Manipulation of the loops increased the resistance to current flow within the wire. Microscopic evaluation showed longitudinal fracture lines at the manipulated sites. Physician-manipulated resectoscope loop angles have a dramatic effect on the strength of the loop as well as the dispersion of energy. A bend of 30 degrees results in 46.7% of the loops failing to meet minimum tensile-strength standards and alters the effectiveness and dispersion of electrical current. Infrared photography confirms the defect to be generated at the point of manipulation, thereby reducing the anticipated capabilities at a constant setting of the loop energizer. Ultimately, the quality of surgical resection suffers from even one manipulation of a resectoscope loop.

    ABSTRACT: Carcinosarcomas of the ureter are rare biphasic neoplasms, with distinct malignant epithelial and mesenchymal components. To the authors' knowledge there have been only 12 cases reported in the literature. Primary cartilaginous tumors of the ureter are also rare tumors. Thus far there has been a single case report of an extraskeletal mesenchymal chondrosarcoma of the ureter in the German literature. Herein a unique case is reported of ureteral carcinosarcoma in an 81-year-old woman presenting with gross hematuria in which the sarcomatous component had extraskeletal mesenchymal chondrosarcomatous differentiation. This is thought to be the first reported case of a carcinosarcoma with such a differentiation in the sarcomatous component.
