In a patient with a distal common bile duct stone, a fracture of the traction wire of the basket occurring during the performance of mechanical lithotripsy resulted in the impaction of the lithotripter basket with a stone. The impacted lithotripter basket combined with a fracture of the traction wire is a rare complication of endoscopic stone removal. We were able to pull the impacted basket us...

Abstract Background Zinner's syndrome is a mesonephric duct anomaly characterized by unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory obstruction due to insult occurred at urogenital tract embryogenesis during the first trimester. In third fourth decades of life, it frequently diagnosed when patients begin be symptomatic, such as lower urinary symptoms, infertility p...

Ureteric bud epithelial cells and metanephric mesenchymal cells that comprise the metanephric kidney primordium are capable of producing nephrons and collecting ducts through reciprocal inductive interaction. Once these cells are induced from pluripotent embryonic stem (ES) cells, they have the potential to become powerful tools in the regeneration of kidney tissues. In this study, we investiga...

generated an excellent animal model for studying the mechanisms underlying the nephropathy associated with human Frasier syndrome and Denys Drash syndrome (DDS). Previous studies in human and mouse have demonstrated that WT1 is essential for the development of kidneys and gonads. The metanephric or permanent Perhaps the biggest surprise to come from the human kidney develops through the interac...

We report here on a case of extrahepatic biliary cystadenoma arising from the common hepatic duct. A 42-year-old woman was evaluated by us to find the cause of her jaundice. Ultrasonography and CT showed a cystic dilatation of the common hepatic duct and also marked dilatation of the intrahepatic duct. Direct cholangiography demonstrated a large filling defect between the left hepatic duct and ...

thyroglossal duct cysts are the most common form of congenital cysts on the neck. the incidence of thyroid papillary carcinoma in thyroglossal duct cyst is less than 1%. in most cases the diagnosis is made postoperatively. we present a 22-year-old female with thyroid papillary carcinoma arising from thyroglossal duct cyst,identified in pathologic study after sistrunk operation.in our case there...
