Calcitonin is a 32 amino acid hormone secreted by the C-cells of the thyroid gland. Calcitonin has been preserved during the transition from ocean-based life to land dwellers and is phylogenetically older than parathyroid hormone. Calcitonin secretion is stimulated by increases in the serum calcium concentration and calcitonin protects against the development of hypercalcemia. Calcitonin is als...

Ureteral stent placement is usual after renal transplantation to avoid ureteral obstruction and facilitate reconstruction. However, stent is prone to infection, encrustation, migration, fragmentation, obstruction, and even obstructive nephropathy with a long-indwelling time. Forgotten ureteric stent in renal transplant recipients is scarcely reported. Here, we present a case of long-forgotten i...

OBJECTIVE Ureteral stents are widely used in endo-urological procedures. However, ureteral stents can be forgotten and cause serious complications, including fragmentation, migration and urosepsis.There are few reports about forgotten and fragmented ureteral stents with stone formation. We aimed to present this rare case with successful combined endo-urological management.

The sequelae from forgotten stents carry significant morbidity and costs. In this study, we attempt to identify potential risk factors that may make patients less likely to follow up for stent removal so that more effective prevention efforts may be directed at these persons. A single-institution retrospective analysis of 187 consecutive patients who had stents placed between January 2010 and D...

Human relations are viewed in terms such as those of the market place. Elements of fairness, reciprocity, and equal sharing are present, but they are always interpreted in a physical, pragmatic way. Reciprocity is a matter of "you scratch...
