Gambaran Makroskopik Dan Mikroskopik Ureter Pada Hewan Coba Postmortem

Abstract

: Postmortem changes provide a lot of valuable information about the time, causes, and mechanisms of death. This study was aimed to obtain an overview of the macroscopic and microscopic postmortem changes of ureter at several time intervals during 48 hours postmortem. This was a descriptive study using pigs as samples. The results showed that macroscopic postmortem changes of ureters began to appear at 5 hours postmortem marked by changes in color, consistency, and length of the ureters. Meanwhile, the microscopic postmortem changes of the ureters began to appear at 4 hours postmortem characterized by congestion, however, the transitional epithelial cell could be identified. At 5 hours postmortem, a number of transitional cells showed pycnotic nuclei. At 15 hous postmortem, the transitional layer began to detach from the lamina propria; cells with pycnotic nuclei increased in number. At 30 hours postmortem, the transitional layer was detached from the lamina propria and in general the structure of ureter layers could not be identified. Conclusion: Macroscopic changes in color, consistency and length of ureter could be observed the earliest at 5 hours postmortem Microscopic changes could be identified at 4 hours postmortem characterized by congestion, however, the transitional cells could be idemtified. At 5 hours postmortem, the early necrosis of transitional cells occured. At 30 hours postmortem the structure of ureter layers could not be identified
