In any urologic cancer surgery, lymph node dissection and its processing play a significant role in staging and management of the patients. Accordingly, precise handling of the dissected lymph nodes is important for histopathological work-up. The authors have developed a lymph node plastic tray shaping the abdomen and pelvis in which the dissected lymph nodes are placed in its determined location. This can be applied for any urologic cancer surgery. The research was designed to test the usage of a new histological tray. The objective was to assess how helpful it was for the surgical team and in the pathological process. The newly developed lymph node tray has been applied in 150 urological cancer surgeries and its efficacy and outcome have been evaluated in all these cases by involved doctors and assistants. This new tray simplifies lymph node removing and identification (staging), making it safer and quicker in any uro-oncological surgery. It facilitates the work of the pathologist and the flow of reliable information along the surgeon—pathologist-oncologist team. With usage of the tray, lymph node dissections are more structured by methodical means compared to any of the present methods.

This paper contains a theoretical formulations and solutions of multiple cracks sub- jected to an anti-plane time-harmonic point load in a functionally graded strip. The distributed dislocation technique is used to construct integral equations for a functionally graded material strip weakened by several cracks under anti-plane time-harmonic load. These equations are of Cauchy singular type at the location of dislocation, which are solved numerically to obtain the dislocation density on the faces of the cracks. The dislocation densities are employed to evaluate the stress intensity factor and strain energy density factors （SEDFs） for multiple cracks with differ- ent configurations. Numerical calculations are presented to show the effects of material properties and the crack configuration on the dynamic stress intensity factors and SEDFs of the functionally graded strip with multiple curved cracks.
