Determination Of The Time Since Death By Histological Changes In Human Pelvis Of Ureter

Abstract :

Introduction: The pelvis of ureter is a funnel like structure from where ureter arises located within the hilum of kidney. Like the urinary bladder and ureter the pelvis of ureter is lined by transitional epithelium. Till now postmortem histological changes have been studied on muscle, kidney, liver, RBC, WBC etc. of various animals. A few studies also performed for same purpose on various organs of human being. The histological changes in kidney and pelvis of ureter after death have been studied in various animals but yet studies with same view which may provide keen and fruitful results for human pelvis of ureter has not been done. Material and Method: In this study 10 cases were studied histologically. Human pelvis of ureter was obtained as and when available from cadavers at the time of autopsy. It was removed from cadaver with a known time of death, where death had resulted from accident. Result: The rate of autolysis was found to be increased with raise in temperature and duration. Retraction and disruption of epithelium with individualization of cells, nuclear pyknosis, karyolysis and loss of epithelial architecture were observed. Muscle layer presented broken fibres and clear spaces. Conclusion: This present study is being carried out with this hope that it will be helpful for estimation of time since death.
