FETAL DISSECTION OF HUMAN KIDNEY MORPHOLOGICAL ANALYSIS
Abstract
BACKGROUND: Adipose tissue surrounds a pair of bean-shaped kidneys that are located posteriorly below the peritoneum, one on either side of the spinal column. The average kidney is 11 cm long, 6 cm wide, and 3 cm thick anteroposteriorly. Lower poles of the kidney are associated with the third lumbar vertebra, whereas upper poles are located at the level of the 12th thoracic vertebra. Because of its proximity to the right lobe of the liver, the right kidney is slightly lower than the left. The left kidney is located closer to the median plane than the right kidney and is a tiny bit longer and narrower. The anterior and posterior aspects that are typically characterized are, in fact, anterolateral and posteromedial because the long axis of each kidney is pointed inferolaterally and the transverse axis posteromedially. Morphological and stereological parameters of developmental anatomy of kidneys are directly related to manifestations of renal disorders. In the present study, the morphological data denoting the various embryonic developmental stages of human fetal kidney were collected and tried to establish the correlation of the same with the gestational age of the fetus and further the histogenesis of the human fetal kidney was also studied in the Indian population.
AIM: Fetal dissection of human kidney morphological analysis. This study provides autopsy standards for body weight, body dimensions, and fresh organ weights for non-macerated fetuses
MATERIAL AND METHOD: This study was carried out in the Department of Surgery in the Hospital with the proper approval of the ethics committee, the medical director, and the department head. The abortus/fetus used in this study were gathered from the Department of Surgery and Obstetrics and Gynecology. 40 fetuses between the ages of 14 and 40 weeks were gathered. For the benefit of the parents and close relatives, the consent form was written in both Hindi and English. Once we receive information from sister-in-charge of labor room about availability of fetus, we immediately rushed to the labor room.
RESULTS: It was observed that the length, thickness and the circumference of the both the kidneys showed a steady rise over the period of gestational developmental age. The mean width of both the kidneys slows down in the growth as the gestation progresses. All the parameters of the right and left kidneys were closely comparable for any of the four groups identified in the present study.
CONCLUSION: It was concluded that in the present study that fetal weight in the population is lower than the same from Nepal as well as Eastern India. Up to second trimester end, the Gujarati fetuses were found to be heavier than the American fetuses. At terms, the Dennis, the Australian and the Gujarati fetuses were comparable in weight. In the last trimester, fetuses of Gujarati population weigh lighter than the same from the French.
