PATHOLOGIC PROCESSES IN HYDRONEPHROSIS

Hydronephrosis

Hydronephrosis means dilation of the pelvis of the kidney by urine which has accumulated, because of obstruction of the urinary tract at some point distal to the pelvis, most commonly the pelvi-ureteral junction. If the obstruction be at a lower level, the ureter becomes dilated first, and the kidney is involved later. Occasionally the obstruction is confined to one or more of the minor calyces...

Involvement of Kallikrein-Related Peptidases in Normal and Pathologic Processes

Human kallikrein-related peptidases (KLKs) are a subgroup of serine proteases that participate in proteolytic pathways and control protein levels in normal physiology as well as in several pathological conditions. Their complex network of stimulatory and inhibitory interactions may induce inflammatory and immune responses and contribute to the neoplastic phenotype through the regulation of seve...

Biological roles of vascular endothelial cell in various pathologic processes.

As Thorgeirsson and Kawanami reported, vascular endothelium has very important roles in the pathogenesis of various diseases, including atherosclerosis and lung disease. Endothelial cells play important roles in physiological responses, and the endothelial layer in most areas may play a role as a barrier which regulates transfer of varied molecular size substances between the circulating blood ...

Changing trends in characteristics of infantile hydronephrosis

  Background : Hydronephrosis (HN) or calycial dilatation is the most common prenatal urologic abnormality. The aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile HN in previously and recently diagnosed patients.   Methods : 193 children with infantile HN admitted to Ali-asghar Children's Hospital in two different periods (group 1 1997...
