Transl Androl Urol 2014;3(3):320 www.amepc.org/tau Although the concept of ureteral stenting has been around since the 1800s, it was not until the 1960s that the more modern version ureteral stents (at that time referred to as splints) were placed endoscopically. Many of the common problems with ureteral stents (irritative voiding symptoms, hematuria, encrustation, bacterial colonization, etc.)...

In this work, stents were produced from natural origin polysaccharides. Alginate, gellan gum, and a blend of these with gelatin were used to produce hollow tube (stents) following a combination of templated gelation and critical point carbon dioxide drying. Morphological analysis of the surface of the stents was carried out by scanning electron microscopy. Indwelling time, encrustation, and sta...

In renal transplantation surgery, double J stents (DJS) are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmentation, encrustation and rarely sep...

Long-term urinary catheterisation is rarely completely free of complications. Catheter blockage from mineral salt encrustation occurs in 40-50 per cent of patients. Recurrent blockage is distressing to patients and carers and costly to health services in both time and resources. Laboratory-based evidence shows acidic maintenance solutions can be effective in dissolving encrustations. This is su...

A 27-year-old man had inferior myocardial infarction following superficial chest trauma. Coronary arteriography documented an isolated total occlusion of the right coronary artery, probably caused by localized extra-coronary compression, and no other evidence of intrinsic coronary disease. The left anterior descending artery later developed a localized proximal stenosis, most likely due to mura...

In the process of endourological development a variety of foreign bodies have been invented besides urinary catheters, on which biofilm can be formed. Bacteria in the biofilm are less susceptible to antibiotics. An additional problem of medical biomaterials in the urinary tract environment is the development of encrustation and consecutive obstruction. The most promising prevention strategy for...

The crystalline bacterial biofilms that encrust Foley catheters compromise the care of many elderly and disabled patients. The aim of this study was to examine whether the biocide triclosan can prevent encrustation by the mixed flora of uropathogens that commonly infect patients undergoing long-term catheterization. Models of the catheterized bladder were inoculated with communities of organism...
