Gambaran makroskopik dan mikroskopik kandung kemih pada hewan coba postmortem

The aim of this study was to obtain the microscopic and microscopic postmortem changes of urinary bladder in domestic pigs. This was a descriptive observational study. The observations were performed at several time intervals, as follows: 1, 2, 3, 4, 5, 6, 9, 12, 15, 18, 21, 24, 30, 36, 42, and 48 hours postmortem. The macroscopic observation of urinary bladder showed that the organ color became darker at 2-3 hours postmortem, the consistency became soft at 24 hours postmortem, and the organ became flattened and longer at 24-30 hours postmortem. The microscopic changes were epithelial desquamation at 1 hour postmortem which was continued leaving a flat thin basal layer at 24 hours postmortem. Congestion was observed at 1 hour postmortem. Hydropic degeneration of the muscle layer began at 3hours postmortem, and the layer became unidentified at 42 hours postmortem. Epithelial changes were hydropic degeneration, picnotic, and anuclear at 4 hours and were identified until 21 hours postmortem. Debris of necrotic epithelial cells was observed until 36-48 hours postmortem. Conclusion: The earliest macroscopic change started at 3 hours postmortem was the change in color. The earliest microscopic changes started at 1 hour postmortem were epithelial desquamation and congestion.Keywords: macroscopic, microscopic, urinary bladder, postmortem Abstrak: Tujuan penelitian ini untuk mengetahui gambaran perubahan makroskopik dan mikroskopik kandung kemih hewan coba babi postmortem. Jenis penelitian ialah deskriptif observasional. Perubahan diamati pada beberapa interval waktu postmortem: 1 jam, 2 jam, 3 jam, 4 jam, 5 jam, 6 jam, 9 jam, 12 jam, 15 jam, 18 jam, 21 jam, 24 jam, 30 jam, 36 jam, 42 jam, dan 48 jam. Hasil pengamatan makroskopik mendapatkan perubahan warna kandug kemih menjadi lebih gelap dari 2 jam ke 3 jam postmortem, konsistensi berubah dari kenyal menjadi lunak sampai 24 jam postmortem, organ mengempis dan memanjang pada 24 jam sampai 30 jam postmortem. Perubahan mikroskopik berupa deskuamasi sejak 1 jam postmortem dan pada 24 jam postmortem tersisa epitel basal tipis dan rata. Kongesti terlihat sejak 1 jam postmortem. Degenerasi hidrofik pada lapisan otot sejak 3 jam postmortem sampai lapisan tersebut tidak jelas teramati 42 jam postmortem. Perubahan epitel berupa degenerasi hidrofik, inti piknotik, dan anukleus dimulai pada 4 jam postmortem dan terus berlanjut sampai 24 jam postmortem. Debris sel nekrosis terlihat pada 36 sampai 48 jam postmortem. Simpulan: Perubahan makroskopik mulai tampak pada 3 jam postmortem berupa perubahan warna. Perubahan mikroskopik mulai tampak pada 1 jam postmortem berupa deskuamasi epitel dan kongesti.Kata kunci: makroskopik, mikroskopik, kandung kemih, postmortem
