Infection is an inevitable consequence of chronic urinary catheterization with associated problems of recurrent catheter encrustation and blockage experienced by approximately 50% of all long-term catheterized patients. In this work, we have exploited, for the first time, the reported pathogen-induced elevation of urine pH as a trigger for "intelligent" antimicrobial release from novel hydrogel...

Ureteral stents are one of the most commonly used urologic devices with the purpose of establishing and maintaining ureteral patency. They are also associated with a number of complications including infection, migration, stent-related symptoms, and encrustation, leading to lithiasis. Prolonged stent dwell time is associated with a greater degree of these complications. We present the case of a...

Introduction: Indwelling urinary catheters cause a variety of complications including infections, pain and bleeding. Sometimes, the catheter becomes encrusted and blocked. Case Report: A 66-year-old male was presented with increasing suprapubic pain for about two months because of a poorly draining Foley catheter. Two years earlier, the patient had undergone a transurethral resection of the pro...

OBJECTIVE To test the performance and acceptability of an early warning sensor to predict encrustation and blockage of long-term indwelling urinary catheters. PATIENTS AND METHODS In all, 17 long-term indwelling catheter users, 15 'blockers' and two 'non-blockers' (controls) were recruited; 11 participants were followed prospectively until catheter change, three withdrew early and three did n...

A noteworthy specimen recording a syn vivo interaction between stalked echinoderm and tabulate coral is described herein from the middle Silurian (Wenlock: Sheinwoodian) Massie Formation of Ripley County, southeastern Indiana. Part column camerate crinoid Eucalyptocrinites encrusted around entirety its lateral margin by favositid colony. The radially outward orientation corallites on both upper...
