there are occasional reports of using the appendix to replace sections of the ureters, and to our knowledge, only a couple of them were in the left side. we used the appendix as a ureteral substitute in two cases in technically difficult parts, the upper left ureter and the first part of the right ureter. follow-ups of8 years and 6 months in right and left side cases, respectively, are impressi...

Biologic valve re-replacement was examined in a series of 1343 patients who underwent aortic valve replacement at The Prince Charles Hospital, Brisbane, with a cryopreserved or 4 degrees C stored allograft valve or a xenograft valve. A parametric model approach was used to simultaneously model the competing risks of death without re-replacement and re-replacement before death. One hundred eleve...

8 Abstract This research presents a bus fleet replacement optimization model to 9 analyze vehicle replacement decisions when there are competing technologies. The 10 focus of the paper is on sensitivity analysis. Model properties that are useful for 11 sensitive analysis are derived and applied utilizing real-world data from King 12 County (Seattle) transit agency. Two distinct technologies, di...

Background EuroSCORE has been proposed to identify patients at high risk for surgical aortic valve replacement and estimate for them the risk-benefit of percutaneous implantation. However, it has been clearly demonstrated that this system overestimates mortality, particularly in the elderly population undergoing surgery for aortic valve replacement. An actualized model called EuroSCORE II has b...

    Background & Aim: Esophageal replacement is done for patients with long gap esophageal atresia, severe stenosis of esophagus due to gastroesophageal reflux, and burns due to chemical agents. A suitable replacement for esophagus must have the following qualities: appropriate function, no tendency to malignancy, straight direction, no gastroesophageal reflux, and fewer complications. Today ga...
