Published: January 2002

In this article, the blood compatibility of polyurethanes (PUs) made by ourselves for catheters is studied by hemolysis test, platelets adhesion test, kinetic thrombus time test and dynamic clot formation. The results showed that these PUs all have excellent blood compatibility. Among these PUs, H50-100 and H60-100 have best blood compatibility. Additionally, the relationship between the structure and blood compatibility is discussed.

Objectives: BK virus (BKV) is highly seroprevalent in humans. After primary infection, it remains latent in the urinary tract and can reactivate in immunocompromised individuals, leading to interstitial nephropathy or hemorrhagic cystitis. The BKV viral load (VL) in plasma correlates with the occurrence of nephropathy and can be monitored in kidney graft recipients; the early detection of BKV viremia can enable an early reduction of immunosuppressant drug doses and the prevention of BKV-associated nephropathy.
